Hello

First - I've updated https://github.com/ops4j/org.ops4j.pax.logging#versions page which now marks only 2 versions as active. Here's more detailed explanation:
  • versions 1.9.x and 1.10.x are pre-refactoring versions without any real integration tests
  • version 1.11.x and 1.12.x are both based on OSGi CMPN Log service 1.3, but version 1.11.x includes Log4j1 backend. I've decided to keep and maintain only version 1.12.x, because we don't want to use Log4j1 backend anymore. The Log4j1 API is still available though. So please use 1.12.x for Felix 5.6 / Karaf 4.2
  • version 2.0.x (with Log4j1 backend) and 2.1.x (without Log4j1 backend) are based on OSGi CMPN Log service 1.4 and because Log service 1.5 is identical, I've decided to keep and maintain only version 2.2.x
The most important change in 1.12.4 and 2.2.1 is related to SLF4J 2.x API support. Actually the interfaces didn't change since version 1.7.x, but there was a change with discovery of logging backend. Instead of static org.slf4j.impl.StaticLoggerBinder, SLF4J 2 now relies on /META-INF/services/org.slf4j.spi.SLF4JServiceProvider which is now providing org.ops4j.pax.logging.slf4j.PaxLoggingSLF4JServiceProvider service.

From the API point of view nothing has changed except that pax-logging-api now exports `org.slf4j` package with version 2.0.6 (in addition to version 1.4, 1.5, 1.6 and 1.7). That's important for OSGi bundles compiled with maven-bundle-plugin (or bnd-maven-plugin) with default configuration which would generate this import header:

Import-Package: org.slf4j;version="[2.0,3.0)".

This would cause problems before Pax Logging 2.2.1 and 1.12.4.

Hello

After previous more important release of Pax Logging 2.2.1 and 1.12.4 where SLF4J 2.0 support was added, I'd like to announce minor releases where only Log4j2 version was upgraded to 2.20.0.

kind regards

Hello

I'd like to announce new release of Pax Logging 2.3.0 and minor releases of existing branches: Pax Logging 1.12.12 (OSGi R6) and 2.2.9 (OSGi R8).

Pax Logging 2.3.0 is a new release with new version of Logback that requires at least JDK 11 (that's why new version line - 2.3.x).

Dependencies were upgraded to newest versions (Tomcat JULI, Reload4j, Commons Logging).

Additionally Pax Logging also exports JULI packages at version 10, 10.1 and 11 (for upcoming Pax Web 10).

There's one issue fixed where new JUL loggers didn't use OSGI configuration - thanks github.com/ffays for the report!

Hello

I'd like to announce new release of Pax URL 2.6.17 and 3.0.1.

These are micro releases:
  • Pax URL 2.6.17 fixes memory leak with LocalRepository instance (thanks Felix Marx for finding it!).
  • Pax URL 2.6.17 again should work with JDK8
  • Pax URL 3.0.1 brings back Maven dependency on org.slf4j:jcl-over-slf4j which was missing, so it broke some deployment scenarios
