Hello all,
I am happy to announce the immediate availability of SLF4J version
1.7.2. The 1.7.x series adds varargs support in Logger methods. The
relevant artifacts should hit the Maven central repository within the
next few hours.
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 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.
At initialization time, if SLF4J suspects that there may be an api
vs. binding version mismatch problem, it will emit a warning about the
suspected mismatch.
Version 1.7.x series takes compatibility one step further so that
slf4j-api and SLF4J bindings can be freely mixed with artifacts from
the 1.6.x or 1.7.x series. In other words, when running under JDK 1.5
or later, version 1.7.x is totally 100% no-ifs-or-buts compatible with
the 1.6.x series.
