Updated version of SOLR?

[Sunny Bassan]

I have noticed that SOLR is stuck on Version 1.2, although this is quite
fine because it works well, I see that Lucene is now up at Version 2.3.2
well beyond the version that is supporting SOLR 1.2. Does anybody know
if there is an updated SOLR version working with the new Lucene
foundation, or is this something we have to integrate ourselves? 
 
I do hope that integrating ourselves is not an option.
