Official releases are usually created when the developers feel there are sufficient changes, improvements and bug fixes to warrant a release. Due to the voluntary nature of Lucene, no releases are scheduled in advance. System Requirements are detailed here.

Older releases ¶
Archives for all past versions of Lucene are available at the Apache archives.
The lucene-VERSION.zip or .tar.gz (where VERSION is the version number of the release, e.g. 3.0.1) file contains the lucene-core jar file, html documentation, a demo application (see the "Getting Started" section) and various jar files containing contributed code. The lucene-VERSION-src.zip or .tar.gz contains the full source code for that version.
