[qos.ch-announce] Release of SLF4J version 2.0.9

[QOS.ch annoucements]

Hello All,

I am very pleased to announce the release of SLF4J version 2.0.9.

It is now possible to specify the provider class explicitly via the
"slf4j.provider" system property, yielding full control of provider
loading to the end-user. Moreover,  the "slf4j.provider"  system
property bypasses the service loader mechanism for finding  providers
and may shorten SLF4J initialization.

A "Bill of Materials" (BOM) file was added to the SLF4J project. This
was a frequently requested feature. Garret Wilson's "Improving  the
Maven Bill of Materials (BOM) Pattern" document was instrumental in
making this happen.

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

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.

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, more
specifically classes in the org.slf4j package, are backward
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.
