Solr 5.0 NOT released - tweet is incorrect

[Shawn Heisey <so...@elyograg.org>]

Someone tweeted with the #solr hashtag that Solr 5.0 is released.

This 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

I foresee two likely reasons for a branch-off.  Based on what I've 
noticed over the last year or so, the latter reason is probably more 
likely.  I don't think that the decision to branch will depend much on 
whether the improvements are in Solr or Lucene, mostly because they tend 
to improve together, not separately.


1) Trunk gets really awesome features X, Y, and Z that aren't included 
in 4x, and it becomes stable enough that the committers believe the 
entire codebase is almost ready for ALPHA.  This reason is more likely 
if those features are major performance enhancements.


2) Backporting fixes from trunk to branch_4x becomes too difficult due 
to code divergence.  Right now, almost all changes backport with no 
difficulty, and even when there are conflicts, they tend to be easy to 
resolve.

Over time, various factors will cause trunk code to become very 
different from 4x, and backporting will become a nightmare.  Examples:

A) Pieces of code that get deprecated in 4x are removed completely from 
trunk.  B) Trunk requires Java 7 and 4x must work with Java 6.  C) There 
are differences that appear because some changes are too major and not 
tested enough to include in the stable branch.

Should we worry about Stock Options being shorted?

Just kidding. :-)

P.s. As an aside, being relatively new, I do wonder what kind of
event/discussion will trigger version 5 branch-off. I guess it would
actually be more of a Lucene decision these days.
