slf4j2-impl not published with 3.0.0-beta3

[hudson155]

When 3.0.0-beta3 was published, I think slf4j2-impl wasn't published alongside it:
https://mvnrepository.com/artifact/org.apache.logging.log4j/log4j-slf4j2-impl

As detailed in the API page of the Log4j 3 manual,

Starting with version 2.24.0, Log4j API is embraced as the target logging API for both Log4j 2 and Log4j 3. Hence, Log4j 3 does not contain a Log4j API module, but instead implements "the" Log4j API developed in Log4j 2 branch. This ensures Log4j 2 users can safely migrate to Log4j 3 without any Log4j API compatibility concerns.

Since log4j-slf4j2-impl is a bridge from SLF4J to Log4j API, it is independent of the Log4j API implementation. That is, it can be used by both Log4j API implementations (i.e., Log4j Core) shipped in Log4j 2 and Log4j 3. See the Installation page for an elaborate explanation of concepts such as logging APIs, implementations, and bridges.

I strongly advise you to use log4j-bom, which takes care of the entire Log4j dependency version management, so that you don't need to worry which version to use where.
