Hello all,

I am very happy to announce the immediate availability of SLF4J
version 1.7.34.

In this release, the "slf4j-log4j12" artifact automatically instructs
Maven to use the "slf4j-reload4j" artifact instead. As you might have
guessed, the "slf4j-reload4j" binding delegates log processing to the
reload4j logging framework.

The reload4j project is a fork of Apache log4j version 1.2.17 with the
goal of fixing pressing security issues. It is intended as a drop-in
replacement for log4j version 1.2.17. By drop-in, we mean the
replacement of log4j.jar with reload4j.jar in your build with no source
code changes in .java files being necessary.

Reload4j project web site:  https://reload4j.qos.ch/

If you are using slf4j-log4j12 as your binding of choice, please
consider using slf4j-reload4j instead. In SLF4J version 1.7.34 and
later, this redirection is seamless and automatic.

Please refer to the the news page for more details on this release:

The relevant artifacts should hit the Maven central repository within
the next few hours.

The 1.7.x series:

The Simple Logging Facade for Java or (SLF4J) serves as a simple facade
or abstraction for various logging frameworks, e.g. java.util.logging,
reload4j and logback, allowing the end user to plug in the
desired logging framework at deployment time.

Binary compatibility:

Mixing mixing different versions of slf4j-api.jar and SLF4J binding
can cause problems. For example, if you are using slf4j-api-1.7.1.jar,
then you should also use slf4j-simple-1.7.1.jar, using
slf4j-simple-1.5.5.jar will not work.

>From the client's perspective all versions of slf4j-api are
compatible. Client code compiled with slf4j-api-N.jar will run
perfectly fine with slf4j-api-M.jar for any N and M. You only need to
ensure that the version of your binding matches that of the
slf4j-api.jar. You do not have to worry about the version of
slf4j-api.jar used to compile a given dependency in your project. You
can always use *any* version of slf4j-api.jar, and as long as the
version of slf4j-api.jar and its binding match, you should be fine.

Downloading SLF4J:

You can download SLF4J, including full source code, class files and
documentation from Maven central under the "org.slf4j" groupId.
