Hello all, I am pleased to announce SLF4J 2.0.0-alpha4. This release contains the slf4j-jdk-platform module which adds support for the Java Platform Logging API (JEP 264). 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 (JSR 376). The 2.0.x series requires Java 8. Please refer to the the news page for more details on this release: http://www.slf4j.org/news.html 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. 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.
