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 Solr, no releases are scheduled in advance.

Latest version

Both binary and source releases for the latest version of Solr are available from the Apache Mirrors.

Past versions

Archives for all past versions of Solr are available at the Apache archives.

File names

The or solr-VERSION.tgz files (where VERSION is the version number of the release, e.g. 7.3.1) contain Apache Solr, html documentation and a tutorial.

The solr-VERSION-src.tgz file contains the full source code for that version.

Note: prior to the Solr 4.1 release, all distribution and artifact filenames contained an apache- prefix.
