- <h3>December 3rd, 2009 - Release of SLF4J 1.5.10</h3>
-
- <p>SLF4J version 1.5.10 consist of bug fixes and minor
- enhancements. It is totally backward compatible with SLF4J version
- 1.5.8. However, the slf4j-ext module ships with a new package called
- <code>org.slf4j.cal10n</code> which adds <a
- href="localization.html">localized/internationalized logging</a>
- support as a thin layer built upon the <a
- href="http://cal10n.qos.ch">CAL10N API</a>.</p>
-
- <p><a href="http://www.slf4j.org/android/">SLF4J-adroid</a>,
- maintained by <a
- href="http://dbis.cs.unibas.ch/team/thorsten-moller/dbis_staff_view">Thorsten
- Möller</a>, was added as a daugther project of SLF4J.
- </p>
-
- <p>Added missing "Export-Package" declaration for cal10n in the OSGi
- manifest file for sfl4j-ext. This was requested in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=156">bug 156</a> by
- Pete Muir.</p>
-
- <p>In log4j-over-slf4j, added missing log(...) methods as requested
- by Zoltan Szel in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=139">bug report
- 139</a>.</p>
-
- <p>In log4j-over-slf4j, added missing <code>LogManager</code> class
- as requested by Rick Beton in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=150">bug report
- 150</a>.</p>
-
- <p>In the slf4j-ext module, added
- <code>getCopyOfChildTimeInstruments</code> and
- <code>getCopyOfGlobalStopWatch</code> methods to the
- <code>Profiler</code> class. This enables developers to build their
- own output formatters for a given Profiler. This feature was
- requested by David Lindelöf in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=141">bug 141</a>.
- </p>
-
- <p>Fixed a <code>NullPointerEception</code> occuring in unspecified
- conditions as described in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=146">bug report
- 146</a> by Dapeng Ni.</p>
-
- <p>Added missing OSGi manifest to the <em>log4j-over-slf4j</em>
- module as requested by Wade Poziombka in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=117">bug 117</a>.
- </p>
-
- <p>OSGi manifests produced by SLF4J now replace the '-' character by
- '.' in compliance with the OSGi specification. This fixes <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=152">bug 152</a>
- according to the patch supplied by Hugues Malphettes.
- </p>
-
- <p>Fixed packaging issue in jcl104-over-slf4j which inadvertently
- produced a jar file as described in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=151">bug 151</a> by
- Jesse McConnell.</p>

-
- <h3>June 11th, 2009 - Release of SLF4J 1.5.8</h3>
-
- <p>SLF4J version 1.5.8 consist of bug fixes. It is totally backward
- compatible with SLF4J version 1.5.7.</p>
-
- <p>The Maven pom file for the <code>log4j-over-slf4j</code> module
- contained a compile time dependency on the <code>slf4j-jdk14</code>
- module. The dependency should have been declared in the test
- scope. This problem was reported by Jean-Luc Geering on the slf4j
- user list.
- </p>
-
- <h3>June 10th, 2009 - Release of SLF4J 1.5.7</h3>
-
- <p>SLF4J version 1.5.7 consist of bug fixes and minor
- enhancements. It is totally backward compatible with SLF4J version
- 1.5.6.</p>
-
- <p>In SLF4J versions 1.5.5 and 1.5.6, the <code>LoggerFactory</code>
- class which is at the core of SLF4J, if a version compatibility
- issue was detected, accidentally invoked a method which was
- introduced in JDK 1.5. Thus, instead of issuing a clear warning
- message, SLF4J would throw a
- <code>NoClassDefFoundError</code>. Consequently, SLF4J would not run
- with JDK 1.4 and earlier but only if a version incompatibility issue
- was present. For example, if you were mixing
- <em>slf4j-api-1.5.6.jar</em> with <em>slf4j-simple-1.4.2.jar</em>,
- which are mutually incompatible. Please note that this bug affects
- only SLF4J versions 1.5.5 and 1.5.6 <em>and</em> only in the
- presence of incompatible versions of slf4j-api and its binding.
- </p>
-
- <p>SLF4J will now emit a warning if more than one binding is present
- on the class path. This enhancement was proposed in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=132">bug 132</a>
- contributed by by Robert Elliot.
- </p>
-
- <p>The Log interface implementations in the jcl-over-slf4j module
- will now correctly cope with serialization. This fixes <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=79">bug 79</a>
- reported by Mathias Bogaert. Many thanks to Eric Vargo for precisely
- identifying the problem and supplying the corresponding patch.</p>
-
- <p>The log4j-over-slf4j module will now correctly
- interact with logging frameworks supporting location information
- such as java.util.logging and logback. This fixes <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=131">bug 131</a>
- reported by Marc Zampetti.
- </p>
-
- <p><code>SLF4JBridgeHandler</code> will no longer ignore log records
- with an empty message. This fixes <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=108">bug 108</a>
- reported by Pepijn Van Eeckhoudt and independently by Dan Lewis.
- </p>
-
- <p>In case the <code>toString()</code> method of a parameter throws
- an exception, <code>MessageFormatter</code> will now print an error
- message, instead of letting the exception bubble higher up as
- previously. This fixes <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=112">bug 112</a>
- submitted by Joern Huxhorn.

-
- <h3>November 21st, 2008 - Release of SLF4J 1.5.6</h3>
-
- <p>SLF4J version 1.5.6 consists of bug fixes. Users are encouraged
- to upgrade to SLF4J version 1.5.6. The upgrade should pose no
- problems. Nevertheless, you might still want to refer to the SLF4J
- <a href="compatibility.html">compatibility report</a>.
- </p>
-
- <p>Fixed long standing <a
- href="http://jira.qos.ch/browse/LBCLASSIC-87">LBCLASSIC-87</a> and
- its younger sibling <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=113">bug
- 113</a>. With each call to getLogger() method,
- <code>LoggerContext</code> will now retrieve the ILoggerFactory
- afresh from <code>StaticLoggerBinder</code>. This change enables
- context selectors of native implementations, e.g logback, to work
- correctly.
- </p>
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=114">bug
- 114</a> reported by Jason Arndt. Corrected the way
- <code>XLogger</code> (in slf4j-ext) passes its fully qualified class
- name so that the underlying logging system can correctly compute
- location information.
- </p>
-
-
- <p>The <code>install()</code> method of
- <code>SLF4JBridgeHandler</code> will no longer reset the entire
- j.u.l. environment but solely add a <code>SLF4JBridgeHandler</code>
- instance to jul's root logger. By the same token, the
- <code>uninstall()</code> method will remove previously added
- <code>SLF4JBridgeHandler</code> instances without making any other
- modifications to the j.u.l. configuration.
- </p>
-
- <p>Added <code>MDCStrLookup</code> to slf4j-ext. This class can be
- used with Apache Commons Lang's <code>StrSubstitutor</code> class to
- inject values in the SLF4J MDC into strings. Information on
- StrSubstitutor can be found at <a
- href="http://commons.apache.org/lang/api-release/org/apache/commons/lang/text/StrSubstitutor.html">StrSubstitutor
- javadoc</a>.

-
- <h3>October 17th, 2008 - Release of SLF4J 1.5.5</h3>
-
- <p>The version check mechanism introduced in SLF4J 1.5.4 was
- inconsistent with the large size of SLF4J's installed user base. We
- cannot expect external SLF4J implementations to align their release
- schedule with that of SLF4J. Consequently, this SLF4J version,
- namely 1.5.5, retains versions checks but as an elective
- process. For further details see the <a
- href="faq.html#version_checks">relevant entry</a> in the FAQ.
- </p>
-
- <p>You are highly encouraged to upgrade to SLF4J version 1.5.5. The
- upgrade should pose no problems. Nevertheless, you might still want
- to refer to the SLF4J <a href="compatibility.html">compatibility
- report</a>.
- </p>
-
- <h3>October 16th, 2008 - Release of SLF4J 1.5.4</h3>
-
- <p>This version corrects critical bugs.
- </p>
-
- <p>Fixed <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=106">critical bug
- 106</a>. In previous versions of SLF4J, if during the initial
- binding phase, the underlying logging system's default configuration
- created or invoked loggers, a <code>NullPointerException</code>
- would be thrown. Refer to the <a
- href="codes.html#substituteLogger">in error codes</a> document for a
- fuller explanation.</p>
-
- <p>At initialization time, LoggerFactory will now check that the
- version of the slf4j-binding matches that of slf4j-api. If there is
- a mismatch a warning will be issued on the console. This should help
- users identify SLF4J related problems more quickly.</p>
-
- <p>Improvements in documentation as well as fix for <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=102">packaging
- problems</a> related to <em>slf4j-ext</em> module.
- </p>
-
- <p>SLF4JBridgeHandler (part of jul-to-slf4j) now accounts for
- loggers with resourceBundle as well parameters. This feature
- requested by Darryl Smith in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=98">bug 98</a> and
- by Jarek Gawor in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=103">bug
- 103</a>.</p>
-
- <p>We now say that markers contain <em>references</em> to other
- markers. We no longer talk about child markers. The javadocs of the
- <code>Marker</code> interface have been updated to reflect this
- change. Moreover, the <code>hasChildren()</code> method in the
- Marker interface has been deprecated and a new method called
- <code>hasReferences()</code> was added.
- </p>

-
- <h3>September 12th, 2008 - Release of SLF4J 1.5.3</h3>
-
- <p>See also the <a href="compatibility.html#1_5_3">compatibility
- report for this version</a>.
- </p>
-
- <p>Added a new module called slf4j-ext for slf4j-extensions. See <a
- href="extensions.html">its documentation</a> for further
- details.</p>
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=71">bug
- 71</a> which was re-opened by Manfred Geiler. SLF4J loggers now
- survive serialization. By survive serialization, we mean
- that the deserialized logger instance are fully functional. </p>
-
- <p>The fix for <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=68">bug 68</a> as
- implemented in version 1.5.1 was incomplete. Michael Furman supplied
- a more complete fix which was incorporated in this release.</p>
-
- <p>When slf4j bridges, e.g. jcl-over-slf4j or log4j-over-slf4j, were
- used in conjunction with JUL as the underlying logging system,
- JDK14LoggerAdapter created a LogRecord even for disabled log
- statements. This performance issue was reported in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=90">bug 90</a> by
- Matthew Mastracci.
- </p>
-
- <p>Added support for array values, including multi-dimensional
- arrays, as parameters. For example,</p>
- <p class="source">log.debug("{} {}", "A", new int[] {1, 2}});</p>
- <p>will print as "A [1, 2]" instead of "A [I at 6ca1c" as
- previously. This enhancement was proposed by "lizongbo".
- </p>
-
- <p>Parameter substitution code has been simplified. SLF4J now only
- cares about the "{}" formatting anchor, that is the '{' character
- immediately followed by '}'. Previously, the '{' had meaning on its
- own. As a result of this change, users no longer need to escape the
- '{' unless it is immediately followed by '}'. Existing messages
- which escaped standalone '{' character will be printed with a
- preceding backslash. However, no data loss in the printed messages
- will occur.
- </p>
-
- <p>Added missing <code>getInstance</code> methods to the
- <code>Category</code> class in the log4j-over-slf4j module, fixing
- <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=95">bug 95</a>
- reported by Michael Rumpf.</p>
-
- <hr noshade="noshade" size="1"/>
-
- <h3>June 8th, 2008 - Release of SLF4J 1.5.2</h3>
-
- <p>Improvements to SLF4J documentation as well as fix of <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=88">packaging
- problems</a> related to <em>jul-to-slf4j.jar</em> and
- <em>jcl104-over-slf4j.jar</em>.
- </p>
-
- <h3>June 5th, 2008 - Release of SLF4J 1.5.1</h3>
-
- <p>See also the <a href="compatibility.html#1_5_1">compatibility
- report for this version</a>.</p>
-
- <p>In order to support JCL version 1.1.1, the
- <em>jcl<b>104</b>-over-slf4j</em> module was renamed as
- <em>jcl-over-slf4j</em>. SLF4J will no longer ship with
- <em>jcl104-over-slf4j.jar</em> but with <em>jcl-over-slf4j.jar</em>.
- The related work responds to enhancement request discussed in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=85">bug 85</a> as
- reported by Niklas Gustavsson.
- </p>
-
- <p>The <em>slf4j-jcl</em> binding now depends on commons-logging
- version 1.1.1 instead of the older 1.0.4</p>
-
-
- <p>Added a java.util.logging to SLF4J bridge as requested in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=38">bug 38</a> by
- Christian Stein, David Smiley, Johan Ferner, Joern Huxhorn and
- others.
- </p>
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=68">bug
- 68</a> reported by Su Chuan and David Rauschenbach. SLF4J requires
- log4j 1.2.12 or later. However, if an older version of log4j is
- present (lacking the TRACE level), in order to avoid
- NoSuchMethodError exceptions, the SLF4J's
- <code>Log4jLoggerAdapter</code> will map the TRACE level as DEBUG.
- </p>
-
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=78">bug
- 78</a> reported by Venu Thachappilly. If the argument array passed
- to a Logger printing method (debug, info, etc.) was null, a
- <code>NullPointerException</code> was thrown. With the correction,
- the messagePattern is returned as is, without parameter
- substitution.
- </p>
-
-
- <p>Added the <code>getCopyOfContextMap</code> and
- <code>setContextMap</code> methods to the <code>MDCAdapter</code>
- and <code>org.sf4j.MDC</code> classes. This was requested in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=84">bug 84</a> by
- Anton Tagunov.
- </p>
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=74">bug
- 74</a>, an endless recursion problem in Marker.contains method,
- reported by Michael Newcomb. Also added he
- <code>getDetachedMarker</code> method to <code>IMarkerFactor</code>
- and <code>MarkerFactory</code> classes which was indirectly
- requested in bug 74.
- </p>
-
- <p>Added the methods <code>getLevel()</code> and
- <code>getEffectiveLevel()</code> to the <code>Category</code> class
- in log4j-over-slf4j. This addition was requested in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=74">bug 74</a> by
- Michael Newcomb.
- </p>
-
- <p>The <a href="migrator.html">SLF4J Migrator</a>
- tool has been improved to support migration from JUL to SLF4J.
- </p>
-
- <p>In <code>MarkerIgnoringBase</code> class, corrected mapping of
- trace methods with markers to their equivalents without marker
- data. Previously, the mapping was trace to debug. The incorrect
- mapping affected only calls to the trace method with
- markers. Interestingly enough, this bug was picked up by new unit
- tests and has not been reported as a bug by our users.
- </p>
-
-
- <h3>February 26th, 2008 - Release of SLF4J 1.5.0</h3>
-
-
- <p>A tool called <a href="migrator.html">SLF4J Migrator</a> now
- ships with SLF4J. It can help you migrate your project using JCL or
- log4j to use SLF4J instead.
- </p>
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=61">bug
- 61</a> reported by Christopher Sahnwaldt. It is now possible to
- place a backslash in front of a formatting anchor, by escaping the
- backslash. For example, the call to
- <code>MessageFormatter.format("C:\\\\{}", "foo")</code> will now
- correctly return "C:\\foo". The backslash character needs to be
- escaped in Java, which leads to four backslashes.
- </p>
-
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=63">bug
- 63</a> reported by Maarten Bosteels. SLF4J now supports MDC for
- <code>java.util.logging</code> package.
- </p>
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=64">bug
- 64</a> reported by Michal Bernhard. The log4j binding will now alert
- the user if she uses SLF4J with a version of log4j earlier than 1.2.12.
- </p>
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=65">bug
- 65</a> reported by Ben Gidley. Superfluous
- <version>${parent.version}</version> lines have been
- removed from pom.xml files. These lines reportedly confuse certain
- Maven repositories.
- </p>
-
- <p>In the <code>org.apache.log4j.Category</code> class, as
- implemented in the log4j-over-slf4j module, calls to the printing
- trace() are now correctly mapped to SLF4J's trace() printing method
- (instead of debug()). Superfluous printing methods with the
- signature <code>xxxx(Object, Object)</code> and <code>xxxx(String,
- Object, Object)</code> have been removed.
- </p>
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=67">bug
- 67</a> reported by Chris Custine. The manifest file for
- jcl104-over-slf4j now correctly declares version 1.0.4 for the
- exported JCL packages.
- </p>
-
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=69">bug
- 69</a> reported by Joern Huxhorn, who graciously supplied the fix as
- well as a test case. The <code>add</code> method in
- <code>BasicMarker</code> class now correctly prevents multiple
- addition of the same child. Moreover, the <code>remove</code> method
- now correctly removes the specified child marker.
- </p>
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=41">bug
- 41</a> reported by Sebastian Davids. The manifest files of various
- projects now mention J2SE-1.3 as the required execution
- environment.
- </p>
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=71">bug
- 71</a> reported by Manfred Geiler. The SLF4JLog and
- SLF4JLocationAwareLog classes are now serializable solving
- serialization problems encountered with certain libraries which
- attempt to serialize JCL log instances.
- </p>
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=73">bug
- 73</a> reported by Oleg Smirsky. A "Fragment-Host: slf4j.api" line
- has been added to every MANIFEST.MF file exporting
- <code>org.slf4j.impl</code>.
- </p>
-
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=72">bug
- 72</a> reported by Ian Carr. Performance issues with slf4j-jdk14 for
- disabled log statements have now been corrected.
- </p>
-
- <hr noshade="noshade" size="1"/>
-
- <h3>August 20th, 2007 - Release of SLF4J 1.4.3</h3>
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=60">bug
- 60</a> as reported by Costin Leau. OSGI manifest entries now declare
- the correct SLF4J version.
- </p>
-
- <p>Clarified the behavior of the various methods methods in the MDC
- class with respect to "null" parameters. This was requested in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=58">bug 58</a> by
- Sebastian Davids.
- </p>
-
- <p>Removed the slf4j-archetype module because nobody seems to have a
- use for it.</p>
-
- <h3>July 12th, 2007 - Release of SLF4J 1.4.2</h3>
-
- <p>The <a href="log4j-over-slf4j.html">log4j-over-slf4j</a> module
- has been moved back into SLF4J. Originally, this module was part of
- SLF4J and was moved into logback due to the lack of MDC support in
- SLF4J. With version 1.4.2 and the addition of MDC support in SLF4J
- 1.4.1, log4j-over-slf4j returns to its original home. Note that the
- previous name of the module was <a
- href="http://logback.qos.ch/bridge.html">log4j-bridge</a>.
- </p>
-
- <p>Addition of the <code>getMDCAdapter</code> method to
- org.slf4j.MDC class. This allows access to the actual MDC
- implementation which can on occasion come in very handy.

-
-
- <h3>July 4th, 2007 - Release of SLF4J 1.4.1</h3>
-
-
- <p>SLF4J now supports <a href="manual.html#mdc">Mapped Diagnostic
- Contexts</a> (MDC) as requested by Andy Gerweck and Steve Ebersole
- in <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=49">bug
- 49</a>.
- </p>
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=53">bug
- 53</a> as reported by Heinrich Nirschl. The public method
- <code>trace(String)</code> in the <code>Log4jLoggerAdapter</code>
- class incorrectly called the underlying log4j logger with level DEBUG
- instead of TRACE.
- </p>
-
- <p>Fixed various documentation related errors kindly reported by
- Mark Vedder.

- <hr noshade="noshade" size="1"/>
-
-
- <h3>May 16th, 2007 - Release of SLF4J 1.4.0</h3>
-
-
- <p>In response to many user requests over time, the TRACE level has
- been added to <a
- href="api/org/slf4j/Logger.html">org.slf4j.Logger</a>
- interface. Please also see the <a href="faq.html#trace">FAQ entry
- discussing</a> the TRACE level.
- </p>
-
-
- <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=47">bug
- 47</a> as reported by Terry Todd. In previous a SLF4J release the
- <code>org.apache.commons.logging.impl.SLF4FLogFactory</code> class
- was renamed as <code>SLF4JLogFactory</code>. The
- <em>META-INF/services/org.apache.commons.logging.LogFactory</em>
- resource file had not reflected this change. It does now.
- </p>
-
-
- <p>Eric Yung <a
- href="http://www.slf4j.org/pipermail/user/2007-April/000327.html">reported</a>
- that Apache commons-configuration access certain commons-logging
- classes, namely <code>org.apache.commons.logging.impl.NoOpLog</code>
- and SimpleLog, directly. Following Eric's suggestion,
- jcl104-over-slf4j now includes the aforementioned classes.
- </p>
-
-
- <hr noshade="noshade" size="1"/>
-
- <h3>April 15th, 2007 - Release of SLF4J 1.3.1</h3>
-
-
- <p>In response to a <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=39">enhancement
- request</a> made by Michael Newcomb, a marker can now be detached
- from the internal list of the <code>MarkerFactory</code> that
- generated it.
- </p>
-
- <p>Fixed a silly but nonetheless annoying bug where log request of
- level ERROR made through jcl104-over-slf4j would log twice. This bug
- was <a
- href="http://www.slf4j.org/pipermail/user/2007-April/000323.html">reported</a>
- and precisely described by Andrew Cooke.
- </p>
-
-
- <hr noshade="noshade" size="1"/>
-
- <h3>February 25th, 2007 - Release of SLF4J 1.3.0</h3>
-
- <p>This release consists of rearrangement of classes among
- projects. More specifically, the
- <code>org.slf4j.LoggerFactory</code> class is now packaged within
- the <em>slf4j-api.jar</em> file instead of the various slf4j
- bindings. <b>It follows that client code needs to depend on only
- slf4j-api in order to compile, while the various slf4j bindings are
- only needed as runtime dependencies.</b> See also the <a
- href="faq.html#maven2">Maven2-related FAQ entry</a>. Given the
- practical significance of this change, we highly recommend that
- library-authors upgrade to version 1.3 at their earliest
- convenience.
- </p>
-
- <p><a href="http://bugzilla.slf4j.org/show_bug.cgi?id=23">Bug number
- 23</a> has been fixed, at the cost of minor and backward compatible
- changes. In other words, jcl104-over-slf4j now preserves caller
- location information.
- </p>
-
- <p>It is now possible to obtain the root logger of the underlying
- logging implementation by requesting a logger named
- "ROOT". This feature was requested by Sebastien Davids
- in <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=35">bug
- report 35</a>. </p>
-
- <p>For an exact list of changes please refer to the <a

-
- <hr noshade="noshade" size="1"/>
-
- <h3>January 24th, 2007 - Release of SLF4J 1.2</h3>
- <p>This release includes several modifications to make SLF4J
- an <a href="http://www.osgi.org/">OSGi</a>-friendly framework.
- The modules' MANIFEST.MF files now include
- OSGi metadata. Regarding these improvements, and OSGi in general, the
- SLF4J project is happy to welcome John E. Conlon as a new committer.
- </p>
-
- <p>Marker objects are now Serializable.
- </p>
-
- <hr noshade="noshade" size="1"/>
-
- <h3>December 21st, 2006 - Release of SLF4J 1.1.0 (final)</h3>
-
- <p>This release consists of minor bug fixes and documentation
- changes. More importantly, the log4j-over-slf4j module has been
- moved to the logback project, under the name <a
- href="http://logback.qos.ch/bridge.html">log4j-bridge</a>.
- </p>
-
- <p>Added the file "org.apache.commons.logging.LogFactory" under
- META-INF/services directory which went missing in the 1.1.0 series
- of SLF4J. This fixes a compatibility problem with Apache Axis which
- uses its own discovery mechanism, namely, commons-discovery version
- 0.2. The problem was reported in bug <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=33">report 33</a>
- by David Varnes.
- </p>
-
- <p>The file jcl104-over-slf4j.jar had various entries missing in its
- MANIFEST.MF file, as reported by Boris Unkel in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=30">bug number
- 30</a>.
- </p>
-
- <hr noshade="noshade" size="1"/>
-
- <h3>November 16th, 2006 - Release of SLF4J 1.1.0-RC1</h3>
-
- <p>This release consists of packaging related bug fix in addition to
- minor documentation changes.
- </p>
-
- <p>Contrary to RC0, RC1 no longer uses SNAPSHOT versions for the
- slf4j-parent pom. The solution to <a
- href="http://ceki.blogspot.com/2006/11/solution-to-maven2-version-number.html">Maven
- version problem</a> does not work for public projects such as SLF4J
- because SNAPHOTs are not allowed on ibiblio.
- </p>
-
-
- <hr noshade="noshade" size="1"/>
-
- <h3>November 4th, 2006 - Release of SLF4J 1.1.0-RC0</h3>
-
- <p>This release consists of bug fixes. Moreover, since the major
- packaging related changes in 1.1.0-beta0 seem to work well, this
- release is marked as RC0.</p>
-
- <p>Fixed the JDK 1.5 dependency for the SLF4J build, as reported by
- Boris Unkel in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=28">bug number
- 28</a>. SLF4J now explicitly declares a dependency on JDK 1.4 in its
- pom.xml file.
- </p>
-
- <p>Fixed an incorrect reference to the logback project in slf4j-api
- pom file. This bug was reported by Boris Unkel in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=29">bug number
- 29</a>.
- </p>
-
- <p>Fixed a synchronization problem in factories of almost all SLF4J
- bindings. This bug was reported independently by Howard M. Lewis Ship
- and Boris Unkel in bug reports <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=26">26</a> and
- respectively <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=26">27</a>.

-
- <h3>September 7th, 2006 - Release of SLF4J 1.1.0-beta0</h3>
-
- <p>Release 1.1.0-beta0 is a relatively important release with a
- refactoring of the way class files are organized in jar files. In
- previous releases, each binding was self-contained in a single jar
- file. In this release, each and every binding depends on
- <em>slf4j-api.jar</em> which contains the bulk of the classes
- required to use SLF4J, except for one or two adapter classes. Only
- the adapter classes are now shipped with each specific binding jar
- as appropriate for the underlying logging system..
- </p>
-
- <p>This release is built using Maven instead of Ant. As for the java
- code, it has not been changed.</p>
-
- <hr noshade="noshade" size="1"/>
-
- <h3>June 8th, 2006 - Release of SLF4J 1.0.2</h3>
-
- <p>Release 1.0.2 is a maintenance release containing bug fixes
- only.</p>
-
- <ul>
-
- <li>Fixed <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=22">bug number
- 22</a> reported by Bjorn Danielsson. This version of the SLF4J API
- will no longer systematically throw an exception when the
- <code>o.a.c.l.impl.SLF4FLogFactory#release()</code> method is
- invoked. Instead, the <code>release()</code> method will issue a
- <a href="http://www.slf4j.org/codes.html">warning</a>.
-
- </li>
-
- </ul>
-
- <hr noshade="noshade" size="1"/>
-
- <h3>May 1st, 2006 - Release of SLF4J 1.0.1</h3>
-
- <p>Release 1.0.1 is a maintenance release containing bug fixes
- only.</p>
-
- <ul>
-
- <li>Fixed <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=20">bug number
- 20</a> reported by Steve Bate. <code>JDK14LoggerAdapter</code>
- will now correctly relay the logger name to the underlying JDK 14
- logging system.
- </li>
-
- <li>Added the file "org.apache.commons.logging.LogFactory" under
- META-INF/services directory in the jcl104-over-slf4j jar
- file. This fixes a compatibility problem with Apache Axis which
- uses its own discovery mechanism, namely, commons-discovery
- version 0.2. The bug was reported by Dave Wallace.
- </li>
-
- </ul>
-

- <hr noshade="noshade" size="1"/>
-
- <h3>March 8th, 2006 - Release of SLF4J 1.0</h3>
-
- <p>This is release labeled as 1.0 (final) contains few relatively
- minor changes:
- </p>
-
- <ul>
- <li>As <a
- href="http://marc.theaimsgroup.com/?t=114063163800004">discussed</a>
- on the slf4j user list, <code>SimpleLogger</code> now directs its
- output to stderr instead of stdout.
- </li>
-
- <li>Modified <code>JDK14LoggerAdapter</code> so that caller
- information is now correctly printed, as reported in <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=13">bug 13</a> by
- Peter Royal.
- </li>
-
- <li>Minor additions to the Marker interface.</li>
-
- </ul>
-
- <hr noshade="noshade" size="1"/>
-
- <h3>February 4th, 2006 - Release of SLF4J 1.0-RC6 and NLOG4J
- 1.2.22</h3>
-
- <p>The <code>MarkingLogger</code> interface has been removed and its
- contents merged into <code>org.slf4j.Logger</code>. This change
- should not adversely affect end-users. However, SLF4J bindings need
- to be updated. This has been done for all the bindings shipped with
- SLF4J distribution as well as NLOG4J. As for x4juli, the update is
- planned for its next release.
- </p>
-
- <p>The merge between the <code>MarkingLogger</code> and
- <code>Logger</code> interfaces has been motivated by the need to
- allow end-users to easily switch between logging systems that
- support markers and those that do not.
- </p>
-
- <p>Added a default instance to SimpleLoggerFactory to serve as a
- last resort fallback mechanism. This instance is designed to be used
- by a very specific group of users, namely for those developing
- logging systems (e.g. log4j or LOGBack). It is not intended for
- end-users of the SLF4J API.

-
- <h3>January 9th, 2006 - Release of SLF4J 1.0-RC5 and NLOG4J
- 1.2.21</h3>
-
- <p>A maintenance release correcting bugs <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=11">#11</a> and <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=12">#12</a> and in
- general improved resilience to null input parameters across
- implementations. Many thanks to Boris Unckel and Kenneth for
- reporting the null input issue.

-
- <hr noshade="noshade" size="1"/>
-
- <h3>December 27th, 2005 - Release of SLF4J 1.0-RC4 and NLOG4J
- 1.2.20</h3>
-
-
- <p>The printing methods in <code>org.slf4j.Logger</code> interface
- now support passing 3 or more parameters in an <code>Object</code>
- array. This was a frequently requested feature missing in previous
- versions of SLF4J.
- </p>
-
- <p>NLOG4J 1.2.20 reflects the addition of new methods in the
- <code>org.slf4j.Logger</code> interface.</p>
-
- <hr noshade="noshade" size="1"/>
-
- <h3>December 8th, 2005 - Release of SLF4J 1.0-RC3</h3>
-
- <p>Maintenance release fixing reported bugs <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=6">#6</a> and <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=7">#7</a>.
- </p>
-
-
- <h3>November 28th, 2005 - Release of SLF4J 1.0-RC2</h3>
-
- <p>In response to a request by Greg Wilkins, this release adds the
- jar file <em>slf4j-jcl.jar</em>, an SLF4J binding for JCL. Please
- read the <a href="manual.html#gradual">gradual migration section</a>
- in the manual for more details.
- </p>
-
- <hr noshade="noshade" size="1"/>
-
- <h3>November 21st, 2005 - Release of SLF4J 1.0-RC1</h3>
-
- <p>A maintenance release correcting bugs <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=4">#4</a> and <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=5">#5</a>. Many
- thanks to Christian Beil for accurately reporting bug #4.
- </p>
-
- <p>There has been also an effort to minimize the file sizes of the
- various jar files produced by SLF4J, resulting in jar files
- approximately 40% smaller than in version 1.0beta9.
- </p>
-
- <p>Given that the SLF4J API is now deemed stable, this release is
- marked as RC1, that is release candidate number 1.
- </p>
-
-
- <hr noshade="noshade" size="1"/>
-
- <h3>October 19th, 2005 - Release of SLF4J 1.0-beta9</h3>
-
- <p>The SLF4J distribution now includes two distinct bindings
- <em>slf4j-log4j12.jar</em> and <em>slf4j-log4j13.jar</em> in order
- to differentiate between log4j version 1.2 and version 1.3. This
- distinction is absolutely necessary because log4j 1.2 and 1.3 are
- not run-time compatible, although they are mostly compile-time
- compatible.
- </p>
-
- <hr noshade="noshade" size="1"/>
-
- <h3>October 19th, 2005 - Release of SLF4J 1.0-beta8 and NLOG4J 1.2.18</h3>
-
-
- <p>Added a new SLF4J binding, <em>slf4j-log4j.jar</em>, intended to
- be used in conjunction with vanilla <em>log4j.jar</em>, as
- distributed by the <a href="http://logging.apache.org">Apache
- Logging Services</a> project. The slf4j-log4j binding is quite
- similar in structure to the JDK 1.4 binding that existed
- previously.
- </p>
-
- <p>The slf4j-log4j binding addresses compatibility problems which
- arose when copies of both <em>log4j.jar</em> and <em>nlog4j.jar</em>
- lay on the class path, in particular when it was undesirable or
- impossible to remove the preexisting <em>log4j.jar</em> file.
- </p>
-
- <p>Methods in the <code>org.slf4j.Logger</code> interface related to
- markers were moved to a separate super interface called <a
- href="api/org/slf4j/MarkingLogger.html">
- <code>org.slf4j.MarkingLogger</code></a>. This refactoring reduces
- the weight of the <a href="api/org/slf4j/Logger.html">
- <code>Logger</code></a> interface.
- </p>
-
- <hr noshade="noshade" size="1"/>
-
- <h3>August 28th, 2005 - Release of SLF4J 1.0-beta7 and NLOG4J 1.2.17</h3>
-
- <p>Spurred by <a
- href="http://bugzilla.slf4j.org/show_bug.cgi?id=3">bug report
- #3</a>, SLF4J binding code has been refactored and
- simplified. Logging systems implementing SLF4J interfaces have to
- have less work in order to bind with SLF4J. Moreover, these changes
- have no incidence on the published interface of SLF4J.
- </p>
-
-
- <hr noshade="noshade" size="1"/>
-
- <h3>August 26th, 2005 - Release of SLF4J 1.0-beta6</h3>
-
- <p>To ease migration to SLF4J from JCL, this release includes a jar
- file called <em>jcl-over-slf4j-1.0.4.jar</em>. This jar file can be
- used as drop-in replacement for JCL version 1.0.4. It implements the
- public API of JCL using SLF4J underneath.
- </p>
-
- <p>Thus, you can immediately benefit from the advantages of SLF4J
- without waiting for all the libraries you depend on to migrate to
- SLF4J first.</p>
-
- <hr noshade="noshade" size="1"/>
-
- <h3>August 16th, 2005 - Release of NLOG4J 1.2.16</h3>
-
- <p>This release adds solves a compatibility problem between log4j
- and nlog4j. Previous to this release, code compiled with log4j
- would not run correctly with nlog4j.
- </p>
-
- <p>With the fixes introduced in NLOG4J 1.2.16, code compiled with
- log4j 1.2.x will run without problems when deployed using NLOG4j.
- </p>
-
- <p>However, the inverse is not true. Code compiled with nlog4j can
- only be deployed using nlog4j.
- </p>
-
- <hr noshade="noshade" size="1"/>
-
- <h3>August 12th, 2005 - Release of SLF4J 1.0-beta5 and NLOG4J
- 1.2.15</h3>
-
- <p>This release adds support for the <a
- href="api/org/slf4j/Marker.html">Marker</a> interface. Thus, log
- statements can be decorated with Marker data allowing more
- expressive power in the processing of log statements.
- </p>
-
- <p>For the sake of IoC frameworks, <code>Logger</code> instances can
- new be queried for their <a
- href="api/org/slf4j/Logger.html#getName()">name</a>.
- </p>
-
- <p>With the addition of markers, sub-domains are no longer
- needed.</p>
-
- <p>The <code>LoggerFactoryAdapter</code> has been simplified and
- renamed as <a
- href="api/org/slf4j/ILoggerFactory.html"><code>ILoggerFactory</code></a>.

- <p>Following discussions on the SLF4J developers list, the
- signatures of the printing methods in <a
- href="api/org/slf4j/Logger.html"><code>org.slf4j.Logger</code></a>

+ <h3>December 3rd, 2009 - Release of SLF4J 1.5.10</h3>
+
+ <p>SLF4J version 1.5.10 consist of bug fixes and minor
+ enhancements. It is totally backward compatible with SLF4J version
+ 1.5.8. However, the slf4j-ext module ships with a new package called
+ <code>org.slf4j.cal10n</code> which adds <a
+ href="localization.html">localized/internationalized logging</a>
+ support as a thin layer built upon the <a
+ href="http://cal10n.qos.ch">CAL10N API</a>.</p>
+
+ <p><a href="http://www.slf4j.org/android/">SLF4J-adroid</a>,
+ maintained by <a
+ href="http://dbis.cs.unibas.ch/team/thorsten-moller/dbis_staff_view">Thorsten
+ Möller</a>, was added as a daugther project of SLF4J.
+ </p>
+
+ <p>Added missing "Export-Package" declaration for cal10n in the OSGi
+ manifest file for sfl4j-ext. This was requested in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=156">bug 156</a> by
+ Pete Muir.</p>
+
+ <p>In log4j-over-slf4j, added missing log(...) methods as requested
+ by Zoltan Szel in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=139">bug report
+ 139</a>.</p>
+
+ <p>In log4j-over-slf4j, added missing <code>LogManager</code> class
+ as requested by Rick Beton in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=150">bug report
+ 150</a>.</p>
+
+ <p>In the slf4j-ext module, added
+ <code>getCopyOfChildTimeInstruments</code> and
+ <code>getCopyOfGlobalStopWatch</code> methods to the
+ <code>Profiler</code> class. This enables developers to build their
+ own output formatters for a given Profiler. This feature was
+ requested by David Lindelöf in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=141">bug 141</a>.
+ </p>
+
+ <p>Fixed a <code>NullPointerEception</code> occuring in unspecified
+ conditions as described in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=146">bug report
+ 146</a> by Dapeng Ni.</p>
+
+ <p>Added missing OSGi manifest to the <em>log4j-over-slf4j</em>
+ module as requested by Wade Poziombka in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=117">bug 117</a>.
+ </p>
+
+ <p>OSGi manifests produced by SLF4J now replace the '-' character by
+ '.' in compliance with the OSGi specification. This fixes <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=152">bug 152</a>
+ according to the patch supplied by Hugues Malphettes.
+ </p>
+
+ <p>Fixed packaging issue in jcl104-over-slf4j which inadvertently
+ produced a jar file as described in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=151">bug 151</a> by
+ Jesse McConnell.</p>

+
+ <h3>June 11th, 2009 - Release of SLF4J 1.5.8</h3>
+
+ <p>SLF4J version 1.5.8 consist of bug fixes. It is totally backward
+ compatible with SLF4J version 1.5.7.</p>
+
+ <p>The Maven pom file for the <code>log4j-over-slf4j</code> module
+ contained a compile time dependency on the <code>slf4j-jdk14</code>
+ module. The dependency should have been declared in the test
+ scope. This problem was reported by Jean-Luc Geering on the slf4j
+ user list.
+ </p>
+
+ <h3>June 10th, 2009 - Release of SLF4J 1.5.7</h3>
+
+ <p>SLF4J version 1.5.7 consist of bug fixes and minor
+ enhancements. It is totally backward compatible with SLF4J version
+ 1.5.6.</p>
+
+ <p>In SLF4J versions 1.5.5 and 1.5.6, the <code>LoggerFactory</code>
+ class which is at the core of SLF4J, if a version compatibility
+ issue was detected, accidentally invoked a method which was
+ introduced in JDK 1.5. Thus, instead of issuing a clear warning
+ message, SLF4J would throw a
+ <code>NoClassDefFoundError</code>. Consequently, SLF4J would not run
+ with JDK 1.4 and earlier but only if a version incompatibility issue
+ was present. For example, if you were mixing
+ <em>slf4j-api-1.5.6.jar</em> with <em>slf4j-simple-1.4.2.jar</em>,
+ which are mutually incompatible. Please note that this bug affects
+ only SLF4J versions 1.5.5 and 1.5.6 <em>and</em> only in the
+ presence of incompatible versions of slf4j-api and its binding.
+ </p>
+
+ <p>SLF4J will now emit a warning if more than one binding is present
+ on the class path. This enhancement was proposed in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=132">bug 132</a>
+ contributed by by Robert Elliot.
+ </p>
+
+ <p>The Log interface implementations in the jcl-over-slf4j module
+ will now correctly cope with serialization. This fixes <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=79">bug 79</a>
+ reported by Mathias Bogaert. Many thanks to Eric Vargo for precisely
+ identifying the problem and supplying the corresponding patch.</p>
+
+ <p>The log4j-over-slf4j module will now correctly
+ interact with logging frameworks supporting location information
+ such as java.util.logging and logback. This fixes <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=131">bug 131</a>
+ reported by Marc Zampetti.
+ </p>
+
+ <p><code>SLF4JBridgeHandler</code> will no longer ignore log records
+ with an empty message. This fixes <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=108">bug 108</a>
+ reported by Pepijn Van Eeckhoudt and independently by Dan Lewis.
+ </p>
+
+ <p>In case the <code>toString()</code> method of a parameter throws
+ an exception, <code>MessageFormatter</code> will now print an error
+ message, instead of letting the exception bubble higher up as
+ previously. This fixes <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=112">bug 112</a>
+ submitted by Joern Huxhorn.
+ </p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>November 21st, 2008 - Release of SLF4J 1.5.6</h3>
+
+ <p>SLF4J version 1.5.6 consists of bug fixes. Users are encouraged
+ to upgrade to SLF4J version 1.5.6. The upgrade should pose no
+ problems. Nevertheless, you might still want to refer to the SLF4J
+ <a href="compatibility.html">compatibility report</a>.
+ </p>
+
+ <p>Fixed long standing <a
+ href="http://jira.qos.ch/browse/LBCLASSIC-87">LBCLASSIC-87</a> and
+ its younger sibling <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=113">bug
+ 113</a>. With each call to getLogger() method,
+ <code>LoggerContext</code> will now retrieve the ILoggerFactory
+ afresh from <code>StaticLoggerBinder</code>. This change enables
+ context selectors of native implementations, e.g logback, to work
+ correctly.
+ </p>
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=114">bug
+ 114</a> reported by Jason Arndt. Corrected the way
+ <code>XLogger</code> (in slf4j-ext) passes its fully qualified class
+ name so that the underlying logging system can correctly compute
+ location information.
+ </p>
+
+
+ <p>The <code>install()</code> method of
+ <code>SLF4JBridgeHandler</code> will no longer reset the entire
+ j.u.l. environment but solely add a <code>SLF4JBridgeHandler</code>
+ instance to jul's root logger. By the same token, the
+ <code>uninstall()</code> method will remove previously added
+ <code>SLF4JBridgeHandler</code> instances without making any other
+ modifications to the j.u.l. configuration.
+ </p>
+
+ <p>Added <code>MDCStrLookup</code> to slf4j-ext. This class can be
+ used with Apache Commons Lang's <code>StrSubstitutor</code> class to
+ inject values in the SLF4J MDC into strings. Information on
+ StrSubstitutor can be found at <a
+ href="http://commons.apache.org/lang/api-release/org/apache/commons/lang/text/StrSubstitutor.html">StrSubstitutor
+ javadoc</a>.

+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>October 17th, 2008 - Release of SLF4J 1.5.5</h3>
+
+ <p>The version check mechanism introduced in SLF4J 1.5.4 was
+ inconsistent with the large size of SLF4J's installed user base. We
+ cannot expect external SLF4J implementations to align their release
+ schedule with that of SLF4J. Consequently, this SLF4J version,
+ namely 1.5.5, retains versions checks but as an elective
+ process. For further details see the <a
+ href="faq.html#version_checks">relevant entry</a> in the FAQ.
+ </p>
+
+ <p>You are highly encouraged to upgrade to SLF4J version 1.5.5. The
+ upgrade should pose no problems. Nevertheless, you might still want
+ to refer to the SLF4J <a href="compatibility.html">compatibility
+ report</a>.
+ </p>
+
+ <h3>October 16th, 2008 - Release of SLF4J 1.5.4</h3>
+
+ <p>This version corrects critical bugs.
+ </p>
+
+ <p>Fixed <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=106">critical bug
+ 106</a>. In previous versions of SLF4J, if during the initial
+ binding phase, the underlying logging system's default configuration
+ created or invoked loggers, a <code>NullPointerException</code>
+ would be thrown. Refer to the <a
+ href="codes.html#substituteLogger">in error codes</a> document for a
+ fuller explanation.</p>
+
+ <p>At initialization time, LoggerFactory will now check that the
+ version of the slf4j-binding matches that of slf4j-api. If there is
+ a mismatch a warning will be issued on the console. This should help
+ users identify SLF4J related problems more quickly.</p>
+
+ <p>Improvements in documentation as well as fix for <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=102">packaging
+ problems</a> related to <em>slf4j-ext</em> module.
+ </p>
+
+ <p>SLF4JBridgeHandler (part of jul-to-slf4j) now accounts for
+ loggers with resourceBundle as well parameters. This feature
+ requested by Darryl Smith in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=98">bug 98</a> and
+ by Jarek Gawor in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=103">bug
+ 103</a>.</p>
+
+ <p>We now say that markers contain <em>references</em> to other
+ markers. We no longer talk about child markers. The javadocs of the
+ <code>Marker</code> interface have been updated to reflect this
+ change. Moreover, the <code>hasChildren()</code> method in the
+ Marker interface has been deprecated and a new method called
+ <code>hasReferences()</code> was added.
+ </p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>September 12th, 2008 - Release of SLF4J 1.5.3</h3>
+
+ <p>See also the <a href="compatibility.html#1_5_3">compatibility
+ report for this version</a>.
+ </p>
+
+ <p>Added a new module called slf4j-ext for slf4j-extensions. See <a
+ href="extensions.html">its documentation</a> for further
+ details.</p>
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=71">bug
+ 71</a> which was re-opened by Manfred Geiler. SLF4J loggers now
+ survive serialization. By survive serialization, we mean
+ that the deserialized logger instance are fully functional. </p>
+
+ <p>The fix for <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=68">bug 68</a> as
+ implemented in version 1.5.1 was incomplete. Michael Furman supplied
+ a more complete fix which was incorporated in this release.</p>
+
+ <p>When slf4j bridges, e.g. jcl-over-slf4j or log4j-over-slf4j, were
+ used in conjunction with JUL as the underlying logging system,
+ JDK14LoggerAdapter created a LogRecord even for disabled log
+ statements. This performance issue was reported in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=90">bug 90</a> by
+ Matthew Mastracci.
+ </p>
+
+ <p>Added support for array values, including multi-dimensional
+ arrays, as parameters. For example,</p>
+ <p class="source">log.debug("{} {}", "A", new int[] {1, 2}});</p>
+ <p>will print as "A [1, 2]" instead of "A [I at 6ca1c" as
+ previously. This enhancement was proposed by "lizongbo".
+ </p>
+
+ <p>Parameter substitution code has been simplified. SLF4J now only
+ cares about the "{}" formatting anchor, that is the '{' character
+ immediately followed by '}'. Previously, the '{' had meaning on its
+ own. As a result of this change, users no longer need to escape the
+ '{' unless it is immediately followed by '}'. Existing messages
+ which escaped standalone '{' character will be printed with a
+ preceding backslash. However, no data loss in the printed messages
+ will occur.
+ </p>
+
+ <p>Added missing <code>getInstance</code> methods to the
+ <code>Category</code> class in the log4j-over-slf4j module, fixing
+ <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=95">bug 95</a>
+ reported by Michael Rumpf.</p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>June 8th, 2008 - Release of SLF4J 1.5.2</h3>
+
+ <p>Improvements to SLF4J documentation as well as fix of <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=88">packaging
+ problems</a> related to <em>jul-to-slf4j.jar</em> and
+ <em>jcl104-over-slf4j.jar</em>.
+ </p>
+
+ <h3>June 5th, 2008 - Release of SLF4J 1.5.1</h3>
+
+ <p>See also the <a href="compatibility.html#1_5_1">compatibility
+ report for this version</a>.</p>
+
+ <p>In order to support JCL version 1.1.1, the
+ <em>jcl<b>104</b>-over-slf4j</em> module was renamed as
+ <em>jcl-over-slf4j</em>. SLF4J will no longer ship with
+ <em>jcl104-over-slf4j.jar</em> but with <em>jcl-over-slf4j.jar</em>.
+ The related work responds to enhancement request discussed in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=85">bug 85</a> as
+ reported by Niklas Gustavsson.
+ </p>
+
+ <p>The <em>slf4j-jcl</em> binding now depends on commons-logging
+ version 1.1.1 instead of the older 1.0.4</p>
+
+
+ <p>Added a java.util.logging to SLF4J bridge as requested in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=38">bug 38</a> by
+ Christian Stein, David Smiley, Johan Ferner, Joern Huxhorn and
+ others.
+ </p>
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=68">bug
+ 68</a> reported by Su Chuan and David Rauschenbach. SLF4J requires
+ log4j 1.2.12 or later. However, if an older version of log4j is
+ present (lacking the TRACE level), in order to avoid
+ NoSuchMethodError exceptions, the SLF4J's
+ <code>Log4jLoggerAdapter</code> will map the TRACE level as DEBUG.
+ </p>
+
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=78">bug
+ 78</a> reported by Venu Thachappilly. If the argument array passed
+ to a Logger printing method (debug, info, etc.) was null, a
+ <code>NullPointerException</code> was thrown. With the correction,
+ the messagePattern is returned as is, without parameter
+ substitution.
+ </p>
+
+
+ <p>Added the <code>getCopyOfContextMap</code> and
+ <code>setContextMap</code> methods to the <code>MDCAdapter</code>
+ and <code>org.sf4j.MDC</code> classes. This was requested in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=84">bug 84</a> by
+ Anton Tagunov.
+ </p>
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=74">bug
+ 74</a>, an endless recursion problem in Marker.contains method,
+ reported by Michael Newcomb. Also added he
+ <code>getDetachedMarker</code> method to <code>IMarkerFactor</code>
+ and <code>MarkerFactory</code> classes which was indirectly
+ requested in bug 74.
+ </p>
+
+ <p>Added the methods <code>getLevel()</code> and
+ <code>getEffectiveLevel()</code> to the <code>Category</code> class
+ in log4j-over-slf4j. This addition was requested in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=74">bug 74</a> by
+ Michael Newcomb.
+ </p>
+
+ <p>The <a href="migrator.html">SLF4J Migrator</a>
+ tool has been improved to support migration from JUL to SLF4J.
+ </p>
+
+ <p>In <code>MarkerIgnoringBase</code> class, corrected mapping of
+ trace methods with markers to their equivalents without marker
+ data. Previously, the mapping was trace to debug. The incorrect
+ mapping affected only calls to the trace method with
+ markers. Interestingly enough, this bug was picked up by new unit
+ tests and has not been reported as a bug by our users.
+ </p>
+
+
+ <h3>February 26th, 2008 - Release of SLF4J 1.5.0</h3>
+
+
+ <p>A tool called <a href="migrator.html">SLF4J Migrator</a> now
+ ships with SLF4J. It can help you migrate your project using JCL or
+ log4j to use SLF4J instead.
+ </p>
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=61">bug
+ 61</a> reported by Christopher Sahnwaldt. It is now possible to
+ place a backslash in front of a formatting anchor, by escaping the
+ backslash. For example, the call to
+ <code>MessageFormatter.format("C:\\\\{}", "foo")</code> will now
+ correctly return "C:\\foo". The backslash character needs to be
+ escaped in Java, which leads to four backslashes.
+ </p>
+
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=63">bug
+ 63</a> reported by Maarten Bosteels. SLF4J now supports MDC for
+ <code>java.util.logging</code> package.
+ </p>
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=64">bug
+ 64</a> reported by Michal Bernhard. The log4j binding will now alert
+ the user if she uses SLF4J with a version of log4j earlier than 1.2.12.
+ </p>
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=65">bug
+ 65</a> reported by Ben Gidley. Superfluous
+ <version>${parent.version}</version> lines have been
+ removed from pom.xml files. These lines reportedly confuse certain
+ Maven repositories.
+ </p>
+
+ <p>In the <code>org.apache.log4j.Category</code> class, as
+ implemented in the log4j-over-slf4j module, calls to the printing
+ trace() are now correctly mapped to SLF4J's trace() printing method
+ (instead of debug()). Superfluous printing methods with the
+ signature <code>xxxx(Object, Object)</code> and <code>xxxx(String,
+ Object, Object)</code> have been removed.
+ </p>
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=67">bug
+ 67</a> reported by Chris Custine. The manifest file for
+ jcl104-over-slf4j now correctly declares version 1.0.4 for the
+ exported JCL packages.
+ </p>
+
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=69">bug
+ 69</a> reported by Joern Huxhorn, who graciously supplied the fix as
+ well as a test case. The <code>add</code> method in
+ <code>BasicMarker</code> class now correctly prevents multiple
+ addition of the same child. Moreover, the <code>remove</code> method
+ now correctly removes the specified child marker.
+ </p>
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=41">bug
+ 41</a> reported by Sebastian Davids. The manifest files of various
+ projects now mention J2SE-1.3 as the required execution
+ environment.
+ </p>
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=71">bug
+ 71</a> reported by Manfred Geiler. The SLF4JLog and
+ SLF4JLocationAwareLog classes are now serializable solving
+ serialization problems encountered with certain libraries which
+ attempt to serialize JCL log instances.
+ </p>
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=73">bug
+ 73</a> reported by Oleg Smirsky. A "Fragment-Host: slf4j.api" line
+ has been added to every MANIFEST.MF file exporting
+ <code>org.slf4j.impl</code>.
+ </p>
+
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=72">bug
+ 72</a> reported by Ian Carr. Performance issues with slf4j-jdk14 for
+ disabled log statements have now been corrected.
+ </p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>August 20th, 2007 - Release of SLF4J 1.4.3</h3>
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=60">bug
+ 60</a> as reported by Costin Leau. OSGI manifest entries now declare
+ the correct SLF4J version.
+ </p>
+
+ <p>Clarified the behavior of the various methods methods in the MDC
+ class with respect to "null" parameters. This was requested in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=58">bug 58</a> by
+ Sebastian Davids.
+ </p>
+
+ <p>Removed the slf4j-archetype module because nobody seems to have a
+ use for it.</p>
+
+ <h3>July 12th, 2007 - Release of SLF4J 1.4.2</h3>
+
+ <p>The <a href="log4j-over-slf4j.html">log4j-over-slf4j</a> module
+ has been moved back into SLF4J. Originally, this module was part of
+ SLF4J and was moved into logback due to the lack of MDC support in
+ SLF4J. With version 1.4.2 and the addition of MDC support in SLF4J
+ 1.4.1, log4j-over-slf4j returns to its original home. Note that the
+ previous name of the module was <a
+ href="http://logback.qos.ch/bridge.html">log4j-bridge</a>.
+ </p>
+
+ <p>Addition of the <code>getMDCAdapter</code> method to

+
+ <h3>July 4th, 2007 - Release of SLF4J 1.4.1</h3>
+
+
+ <p>SLF4J now supports <a href="manual.html#mdc">Mapped Diagnostic
+ Contexts</a> (MDC) as requested by Andy Gerweck and Steve Ebersole
+ in <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=49">bug
+ 49</a>.
+ </p>
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=53">bug
+ 53</a> as reported by Heinrich Nirschl. The public method
+ <code>trace(String)</code> in the <code>Log4jLoggerAdapter</code>
+ class incorrectly called the underlying log4j logger with level DEBUG
+ instead of TRACE.
+ </p>
+
+ <p>Fixed various documentation related errors kindly reported by
+ Mark Vedder.
+ </p>
+
+
+ <hr noshade="noshade" size="1"/>
+
+
+ <h3>May 16th, 2007 - Release of SLF4J 1.4.0</h3>
+
+
+ <p>In response to many user requests over time, the TRACE level has
+ been added to <a
+ href="api/org/slf4j/Logger.html">org.slf4j.Logger</a>
+ interface. Please also see the <a href="faq.html#trace">FAQ entry
+ discussing</a> the TRACE level.
+ </p>
+
+
+ <p>Fixed <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=47">bug
+ 47</a> as reported by Terry Todd. In previous a SLF4J release the
+ <code>org.apache.commons.logging.impl.SLF4FLogFactory</code> class
+ was renamed as <code>SLF4JLogFactory</code>. The
+ <em>META-INF/services/org.apache.commons.logging.LogFactory</em>
+ resource file had not reflected this change. It does now.
+ </p>
+
+
+ <p>Eric Yung <a
+ href="http://www.slf4j.org/pipermail/user/2007-April/000327.html">reported</a>
+ that Apache commons-configuration access certain commons-logging
+ classes, namely <code>org.apache.commons.logging.impl.NoOpLog</code>
+ and SimpleLog, directly. Following Eric's suggestion,
+ jcl104-over-slf4j now includes the aforementioned classes.
+ </p>
+
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>April 15th, 2007 - Release of SLF4J 1.3.1</h3>
+
+
+ <p>In response to a <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=39">enhancement
+ request</a> made by Michael Newcomb, a marker can now be detached
+ from the internal list of the <code>MarkerFactory</code> that
+ generated it.
+ </p>
+
+ <p>Fixed a silly but nonetheless annoying bug where log request of
+ level ERROR made through jcl104-over-slf4j would log twice. This bug
+ was <a
+ href="http://www.slf4j.org/pipermail/user/2007-April/000323.html">reported</a>
+ and precisely described by Andrew Cooke.
+ </p>
+
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>February 25th, 2007 - Release of SLF4J 1.3.0</h3>
+
+ <p>This release consists of rearrangement of classes among
+ projects. More specifically, the
+ <code>org.slf4j.LoggerFactory</code> class is now packaged within
+ the <em>slf4j-api.jar</em> file instead of the various slf4j
+ bindings. <b>It follows that client code needs to depend on only
+ slf4j-api in order to compile, while the various slf4j bindings are
+ only needed as runtime dependencies.</b> See also the <a
+ href="faq.html#maven2">Maven2-related FAQ entry</a>. Given the
+ practical significance of this change, we highly recommend that
+ library-authors upgrade to version 1.3 at their earliest
+ convenience.
+ </p>
+
+ <p><a href="http://bugzilla.slf4j.org/show_bug.cgi?id=23">Bug number
+ 23</a> has been fixed, at the cost of minor and backward compatible
+ changes. In other words, jcl104-over-slf4j now preserves caller
+ location information.
+ </p>
+
+ <p>It is now possible to obtain the root logger of the underlying
+ logging implementation by requesting a logger named
+ "ROOT". This feature was requested by Sebastien Davids
+ in <a href="http://bugzilla.slf4j.org/show_bug.cgi?id=35">bug
+ report 35</a>. </p>
+
+ <p>For an exact list of changes please refer to the <a
+ href="changes/changes-1.3.txt">1.3.0 compatibility report</a> file
+ as generated by clirr.</p>
+
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>January 24th, 2007 - Release of SLF4J 1.2</h3>
+ <p>This release includes several modifications to make SLF4J
+ an <a href="http://www.osgi.org/">OSGi</a>-friendly framework.
+ The modules' MANIFEST.MF files now include
+ OSGi metadata. Regarding these improvements, and OSGi in general, the
+ SLF4J project is happy to welcome John E. Conlon as a new committer.
+ </p>
+
+ <p>Marker objects are now Serializable.
+ </p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>December 21st, 2006 - Release of SLF4J 1.1.0 (final)</h3>
+
+ <p>This release consists of minor bug fixes and documentation
+ changes. More importantly, the log4j-over-slf4j module has been
+ moved to the logback project, under the name <a
+ href="http://logback.qos.ch/bridge.html">log4j-bridge</a>.
+ </p>
+
+ <p>Added the file "org.apache.commons.logging.LogFactory" under
+ META-INF/services directory which went missing in the 1.1.0 series
+ of SLF4J. This fixes a compatibility problem with Apache Axis which
+ uses its own discovery mechanism, namely, commons-discovery version
+ 0.2. The problem was reported in bug <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=33">report 33</a>
+ by David Varnes.
+ </p>
+
+ <p>The file jcl104-over-slf4j.jar had various entries missing in its
+ MANIFEST.MF file, as reported by Boris Unkel in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=30">bug number
+ 30</a>.
+ </p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>November 16th, 2006 - Release of SLF4J 1.1.0-RC1</h3>
+
+ <p>This release consists of packaging related bug fix in addition to
+ minor documentation changes.
+ </p>
+
+ <p>Contrary to RC0, RC1 no longer uses SNAPSHOT versions for the
+ slf4j-parent pom. The solution to <a
+ href="http://ceki.blogspot.com/2006/11/solution-to-maven2-version-number.html">Maven
+ version problem</a> does not work for public projects such as SLF4J
+ because SNAPHOTs are not allowed on ibiblio.
+ </p>
+
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>November 4th, 2006 - Release of SLF4J 1.1.0-RC0</h3>
+
+ <p>This release consists of bug fixes. Moreover, since the major
+ packaging related changes in 1.1.0-beta0 seem to work well, this
+ release is marked as RC0.</p>
+
+ <p>Fixed the JDK 1.5 dependency for the SLF4J build, as reported by
+ Boris Unkel in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=28">bug number
+ 28</a>. SLF4J now explicitly declares a dependency on JDK 1.4 in its
+ pom.xml file.
+ </p>
+
+ <p>Fixed an incorrect reference to the logback project in slf4j-api
+ pom file. This bug was reported by Boris Unkel in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=29">bug number
+ 29</a>.
+ </p>
+
+ <p>Fixed a synchronization problem in factories of almost all SLF4J
+ bindings. This bug was reported independently by Howard M. Lewis Ship
+ and Boris Unkel in bug reports <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=26">26</a> and
+ respectively <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=26">27</a>.

+ <hr noshade="noshade" size="1"/>
+
+ <h3>September 7th, 2006 - Release of SLF4J 1.1.0-beta0</h3>
+
+ <p>Release 1.1.0-beta0 is a relatively important release with a
+ refactoring of the way class files are organized in jar files. In
+ previous releases, each binding was self-contained in a single jar
+ file. In this release, each and every binding depends on
+ <em>slf4j-api.jar</em> which contains the bulk of the classes
+ required to use SLF4J, except for one or two adapter classes. Only
+ the adapter classes are now shipped with each specific binding jar
+ as appropriate for the underlying logging system..
+ </p>
+
+ <p>This release is built using Maven instead of Ant. As for the java
+ code, it has not been changed.</p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>June 8th, 2006 - Release of SLF4J 1.0.2</h3>
+
+ <p>Release 1.0.2 is a maintenance release containing bug fixes
+ only.</p>
+
+ <ul>
+
+ <li>Fixed <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=22">bug number
+ 22</a> reported by Bjorn Danielsson. This version of the SLF4J API
+ will no longer systematically throw an exception when the
+ <code>o.a.c.l.impl.SLF4FLogFactory#release()</code> method is
+ invoked. Instead, the <code>release()</code> method will issue a
+ <a href="http://www.slf4j.org/codes.html">warning</a>.
+
+ </li>
+
+ </ul>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>May 1st, 2006 - Release of SLF4J 1.0.1</h3>
+
+ <p>Release 1.0.1 is a maintenance release containing bug fixes
+ only.</p>
+
+ <ul>
+
+ <li>Fixed <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=20">bug number
+ 20</a> reported by Steve Bate. <code>JDK14LoggerAdapter</code>
+ will now correctly relay the logger name to the underlying JDK 14
+ logging system.
+ </li>
+
+ <li>Added the file "org.apache.commons.logging.LogFactory" under
+ META-INF/services directory in the jcl104-over-slf4j jar
+ file. This fixes a compatibility problem with Apache Axis which
+ uses its own discovery mechanism, namely, commons-discovery
+ version 0.2. The bug was reported by Dave Wallace.
+ </li>
+
+ </ul>
+
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>March 8th, 2006 - Release of SLF4J 1.0</h3>
+
+ <p>This is release labeled as 1.0 (final) contains few relatively
+ minor changes:
+ </p>
+
+ <ul>
+ <li>As <a
+ href="http://marc.theaimsgroup.com/?t=114063163800004">discussed</a>
+ on the slf4j user list, <code>SimpleLogger</code> now directs its
+ output to stderr instead of stdout.
+ </li>
+
+ <li>Modified <code>JDK14LoggerAdapter</code> so that caller
+ information is now correctly printed, as reported in <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=13">bug 13</a> by
+ Peter Royal.
+ </li>
+
+ <li>Minor additions to the Marker interface.</li>
+
+ </ul>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>February 4th, 2006 - Release of SLF4J 1.0-RC6 and NLOG4J
+ 1.2.22</h3>
+
+ <p>The <code>MarkingLogger</code> interface has been removed and its
+ contents merged into <code>org.slf4j.Logger</code>. This change
+ should not adversely affect end-users. However, SLF4J bindings need
+ to be updated. This has been done for all the bindings shipped with
+ SLF4J distribution as well as NLOG4J. As for x4juli, the update is
+ planned for its next release.
+ </p>
+
+ <p>The merge between the <code>MarkingLogger</code> and
+ <code>Logger</code> interfaces has been motivated by the need to
+ allow end-users to easily switch between logging systems that
+ support markers and those that do not.
+ </p>
+
+ <p>Added a default instance to SimpleLoggerFactory to serve as a
+ last resort fallback mechanism. This instance is designed to be used
+ by a very specific group of users, namely for those developing
+ logging systems (e.g. log4j or LOGBack). It is not intended for
+ end-users of the SLF4J API.

+
+ <h3>January 9th, 2006 - Release of SLF4J 1.0-RC5 and NLOG4J
+ 1.2.21</h3>
+
+ <p>A maintenance release correcting bugs <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=11">#11</a> and <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=12">#12</a> and in
+ general improved resilience to null input parameters across
+ implementations. Many thanks to Boris Unckel and Kenneth for
+ reporting the null input issue.
+ </p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>December 27th, 2005 - Release of SLF4J 1.0-RC4 and NLOG4J
+ 1.2.20</h3>
+
+
+ <p>The printing methods in <code>org.slf4j.Logger</code> interface
+ now support passing 3 or more parameters in an <code>Object</code>
+ array. This was a frequently requested feature missing in previous
+ versions of SLF4J.
+ </p>
+
+ <p>NLOG4J 1.2.20 reflects the addition of new methods in the
+ <code>org.slf4j.Logger</code> interface.</p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>December 8th, 2005 - Release of SLF4J 1.0-RC3</h3>
+
+ <p>Maintenance release fixing reported bugs <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=6">#6</a> and <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=7">#7</a>.
+ </p>
+
+
+ <h3>November 28th, 2005 - Release of SLF4J 1.0-RC2</h3>
+
+ <p>In response to a request by Greg Wilkins, this release adds the
+ jar file <em>slf4j-jcl.jar</em>, an SLF4J binding for JCL. Please
+ read the <a href="manual.html#gradual">gradual migration section</a>
+ in the manual for more details.
+ </p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>November 21st, 2005 - Release of SLF4J 1.0-RC1</h3>
+
+ <p>A maintenance release correcting bugs <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=4">#4</a> and <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=5">#5</a>. Many
+ thanks to Christian Beil for accurately reporting bug #4.
+ </p>
+
+ <p>There has been also an effort to minimize the file sizes of the
+ various jar files produced by SLF4J, resulting in jar files
+ approximately 40% smaller than in version 1.0beta9.
+ </p>
+
+ <p>Given that the SLF4J API is now deemed stable, this release is
+ marked as RC1, that is release candidate number 1.
+ </p>
+
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>October 19th, 2005 - Release of SLF4J 1.0-beta9</h3>
+
+ <p>The SLF4J distribution now includes two distinct bindings
+ <em>slf4j-log4j12.jar</em> and <em>slf4j-log4j13.jar</em> in order
+ to differentiate between log4j version 1.2 and version 1.3. This
+ distinction is absolutely necessary because log4j 1.2 and 1.3 are
+ not run-time compatible, although they are mostly compile-time
+ compatible.
+ </p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>October 19th, 2005 - Release of SLF4J 1.0-beta8 and NLOG4J 1.2.18</h3>
+
+
+ <p>Added a new SLF4J binding, <em>slf4j-log4j.jar</em>, intended to
+ be used in conjunction with vanilla <em>log4j.jar</em>, as
+ distributed by the <a href="http://logging.apache.org">Apache
+ Logging Services</a> project. The slf4j-log4j binding is quite
+ similar in structure to the JDK 1.4 binding that existed
+ previously.
+ </p>
+
+ <p>The slf4j-log4j binding addresses compatibility problems which
+ arose when copies of both <em>log4j.jar</em> and <em>nlog4j.jar</em>
+ lay on the class path, in particular when it was undesirable or
+ impossible to remove the preexisting <em>log4j.jar</em> file.
+ </p>
+
+ <p>Methods in the <code>org.slf4j.Logger</code> interface related to
+ markers were moved to a separate super interface called <a
+ href="api/org/slf4j/MarkingLogger.html">
+ <code>org.slf4j.MarkingLogger</code></a>. This refactoring reduces
+ the weight of the <a href="api/org/slf4j/Logger.html">
+ <code>Logger</code></a> interface.
+ </p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>August 28th, 2005 - Release of SLF4J 1.0-beta7 and NLOG4J 1.2.17</h3>
+
+ <p>Spurred by <a
+ href="http://bugzilla.slf4j.org/show_bug.cgi?id=3">bug report
+ #3</a>, SLF4J binding code has been refactored and
+ simplified. Logging systems implementing SLF4J interfaces have to
+ have less work in order to bind with SLF4J. Moreover, these changes
+ have no incidence on the published interface of SLF4J.
+ </p>
+
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>August 26th, 2005 - Release of SLF4J 1.0-beta6</h3>
+
+ <p>To ease migration to SLF4J from JCL, this release includes a jar
+ file called <em>jcl-over-slf4j-1.0.4.jar</em>. This jar file can be
+ used as drop-in replacement for JCL version 1.0.4. It implements the
+ public API of JCL using SLF4J underneath.
+ </p>
+
+ <p>Thus, you can immediately benefit from the advantages of SLF4J
+ without waiting for all the libraries you depend on to migrate to
+ SLF4J first.</p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>August 16th, 2005 - Release of NLOG4J 1.2.16</h3>
+
+ <p>This release adds solves a compatibility problem between log4j
+ and nlog4j. Previous to this release, code compiled with log4j
+ would not run correctly with nlog4j.
+ </p>
+
+ <p>With the fixes introduced in NLOG4J 1.2.16, code compiled with
+ log4j 1.2.x will run without problems when deployed using NLOG4j.
+ </p>
+
+ <p>However, the inverse is not true. Code compiled with nlog4j can
+ only be deployed using nlog4j.
+ </p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>August 12th, 2005 - Release of SLF4J 1.0-beta5 and NLOG4J
+ 1.2.15</h3>
+
+ <p>This release adds support for the <a
+ href="api/org/slf4j/Marker.html">Marker</a> interface. Thus, log
+ statements can be decorated with Marker data allowing more
+ expressive power in the processing of log statements.
+ </p>
+
+ <p>For the sake of IoC frameworks, <code>Logger</code> instances can
+ new be queried for their <a
+ href="api/org/slf4j/Logger.html#getName()">name</a>.
+ </p>
+
+ <p>With the addition of markers, sub-domains are no longer
+ needed.</p>
+
+ <p>The <code>LoggerFactoryAdapter</code> has been simplified and
+ renamed as <a
+ href="api/org/slf4j/ILoggerFactory.html"><code>ILoggerFactory</code></a>.
+ </p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>July 5th, 2005 - Release of NLOG4J 1.2.14</h3>
+
+ <p>This release fixes compatibility problems between NLOG4J and
+ Jakarta Commons Logging.
+ </p>
+
+ <hr noshade="noshade" size="1"/>
+
+ <h3>June 28th, 2005 - Release of SLF4J 1.0-beta4 and NLOG4J
+ 1.2.13</h3>
+
+ <p>Following discussions on the SLF4J developers list, the
+ signatures of the printing methods in <a
+ href="api/org/slf4j/Logger.html"><code>org.slf4j.Logger</code></a>
+ interface have been modified to admit messages of type
+ <code>String</code> instead of type <code>Object</code> as
+ previously. The current set of printing methods is listed below.
