[Chetan Mehrotra <ch...@gmail.com>]

The Apache Sling team is pleased to announce the release of Apache
Sling Commons Log version 4.0.0

Apache Sling is a web framework that uses a Java Content Repository,
such as Apache Jackrabbit, to store and manage content. Sling
applications use either scripts or Java servlets, selected based on
simple name conventions, to process HTTP requests in a RESTful way.

Sling Commons Log bundle provides logging support based on Logback in
OSGi env. Apart from default Logback feature set it enables extending
Logback via OSGi constructs
