Yes, it started in March.  Development is combined (committers, dev
list, etc), but separate downloads and user lists will remain.

Lots of other stuff has changed.  For example, trunk is now always the
next *major* version number.
So the trunk of the combined lucene/solr is 4.0-dev

There is now a branch_3x that is like trunk for all future 3.x releases.

The next version of Solr will probably be 3.1, and it's unlikely there
will ever be a 1.5 released.

Yes, Lucene/Solr aims for a "stable" trunk (runtime stability, not API
stability).  Plenty of big companies use trunk since they need recent
features.  Just be sure to test well (good advice even if working off
of officially released versions).
