Hello all,

I am very happy to announce the immediate availability of SLF4J
version 1.7.33.

This release adds the "slf4j-reload4j" module which delegates logging
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.

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

    http://www.slf4j.org/news.html

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,
log4j 1.x, 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.
