My best guess (and it is just a guess) is between December and March. The roots of Solr 4 which triggered the major version change is known as "flexible indexing" (or just "flex" for short amongst developers). The genesis of it was posted to JIRA as a patch on 18 November 2008 -- LUCENE-1458 (almost 3 years ago!). About a year later it was committed into a special flex branch that is probably gone now, and then around April/early-May 2010, it went into trunk whereas the pre-flex code on trunk went to a newly formed 3x branch. That is ancient history now, and there are some amazing performance improvements tied to flex that haven't seen the light of day in an official release. It's a shame, really. So it's been so long that, well, after it dawns on everyone that it that the code is 3 friggin years old without a release -- it's time to get on with the show.
