[slf4j-dev] Release of SLF4J version 2.0.0

[Ceki Gülcü]

Hello all,

After a very long gestation period, I am pleased to announce SLF4J 2.0.0.

The 2.0.x series introduces a backward-compatible fluent logging API.
By backward-compatible, we mean that existing logging frameworks do not
have to be changed in order for the user to benefit from the fluent
logging API. However, existing frameworks *must* migrate to the
ServiceLoader mechanism. The resulting internal changes are detailed in
the FAQ page.

  http://www.slf4j.org/faq.html#changesInVersion200

The  2.0.x series  builds upon  the  the 1.8.x  series which  was
modularized per Java Platform Module System (JPMS/Jigsaw).

The 2.0.x series requires Java 8.

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

Binary compatibility:

Mixing mixing different versions of slf4j-api.jar and SLF4J provider can
cause problems.  For example, if you are using
slf4j-api-2.0.0.jar, then you should also use slf4j-simple-2.0.0.jar,
using slf4j-simple-1.5.5.jar will not work.

With the exception of the fluent API (new in SLF4J 2.0.x), 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 provider 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
provider match, you should be fine.
