Release of SLF4J version 2.0.0-alpha4
by QOS.ch annoucements 12 Aug '21

12 Aug '21

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. Downloading SLF4J: You can download SLF4J, including full source code, class files and documentation on our download page: http://www.slf4j.org/download.html Announcement mailing list: You can receive SLF4J related announcements by subscribing to the SLF4J announce mailing list.

Release of logback version 1.3.0-alpha7
by QOS.ch annoucements 10 Aug '21

10 Aug '21

Hello all, I am happy to announce the release of logback version 1.3.0-alpha7. It reuires slf4j-api version 2.0.0-alpha3 or later. This version supports the fluent-API introduced in SLF4J 2.0.x. It also supports Jigsaw/Java9 modularization. Joran, logback's configuration system, has been rewritten to use an internal representation model which can be processed separately. Given the breadth of the changes, support for SiftingAppender and Groovy configuration have been dropped temporarily. No new features are available in this version. Future releases will gradually introduce new features made possible by Joran representation model. The 1.3.x series requires Java 8 at runtime. If you wish to build logback from source, you will need Java 9. Please refer to the news page for precise details. http://logback.qos.ch/news.html You can receive logback related announcements by subscribing to the QOS.ch announce mailing list.
