Someone tweeted with the #solr hashtag that Solr 5.0 is released.
https://twitter.com/nadrThis is not correct. At this time, version 4.3.0 is the current release. I expect that the announcement for 4.3.1 will appear within the next couple of days.
Right now, there is no timeframe for the 5.0 release. The trunk 'branch' is very similar to 4.x. There's no compelling reason to work on a 5.0 version yet.
Thanks, Shawn
