Hello all,
After a long estation period, I am very pleased to announce SLF4J
version 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.
