Voting starts in March for the Drupal Association Board election.
This is the issue to track the status of my GSoC 2011 project on Apache Mahout integration. The description of the project is at: http://groups.drupal.org/node/145339
7.x-1.x: Will be actively developed and maintained. Will finish before the summer ends. Will include Apache Mahout integration and Views support.
6.x-3.x: Will be the back port of Apache Mahout integration and Views support to Drupal6.
6.x-2.x: The last release of Recommender API using the old PHP code. Will not continue new development. The last version is 6.x-2.0-beta4. HEAD contains some unfinished code changes. Maintenance patch (if any) will go to 6.x-2.0-beta4.
