Hello all,

I am happy to announce the immediate availability of SLF4J version
1.7.0. This version adds varargs support in Logger methods. (Hey, it
only took 6 years!) 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-1.7.0.jar,
then you should also use slf4j-simple-1.7.0.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 by 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 1.7.0 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 1.7.0 is totally 100% no-ifs-or-buts compatible with the 1.6.x
