--------------------------------------------------

  = Solr 3.1 =
  
- Solr 3.1 has not been released.
+ Solr 3.1 was released March 2011
  
- Please see [[FrontPage#solr_development|Solr Development]] for links to nightly builds that contain the latest 3.1 functionality.
+ This is the first release after Solr 1.4.1.
+ Lucene and Solr's version numbers were synced following the Lucene/Solr merge (hence the 3.1 directly after the 1.4 line).
+ Solr 3.1 contains Lucene 3.1.
  
- Solr 3.1 refers to the next hypothetical release off of the [[http://svn.apache.org/viewvc/lucene/dev/branches/branch_3x/|"3x" branch]] that was created after it was decided that the development of Solr and Lucene-Java should be more tightly integrated, (the version number and branch name come from following the Lucene-Java release version convention)

+ == Release Announcement ==
+ March 2011, Apache Solr 3.1 available
  
+ The Lucene PMC is pleased to announce the release of Apache Solr 3.1.
+ 
+ This release contains numerous bug fixes, optimizations, and
+ improvements, some of which are highlighted below.  The release is
+ available for immediate download at http://www.apache.org/dyn/closer.cgi/lucene/solr.
+ See the CHANGES.txt file included with the release for a full list of
+ details as well as instructions on upgrading.
+ 
+ What's in a Version? 
+ 
+ The version number for Solr 3.1 was chosen to reflect the merge of
+ development with Lucene, which is currently also on 3.1.  Going
+ forward, we expect the Solr version to be the same as the Lucene
+ version.  Solr 3.1 contains Lucene 3.1 and is the release after Solr 1.4.1.
