Lucene versions in upcoming solr release

[entdeveloper <ca...@gmail.com>]

It's my understanding that Solr 1.4, which is to be released any day now,
will be based on version 2.9 of lucene.  It's also my understanding that
lucene 3.0 will be released very shortly as well.  Is there a plan to update
Solr to use lucene 3.0 shortly after that?

Just trying to decide if we should wait if there are going to be 2 releases
very close to one another.

Serious bugs were found in Lucene 2.9.0... we are all set to release
when Lucene 2.9.1 is released, which is supposed to happen any time
now.  If it doesn't we may have to release on a dev version of the
2.9.1 branch.

No, Lucene 3.0 will mainly convert to Java5 and remove deprecations.
There should be no new features which Solr could take advantage of,
and dealing with all of the changes will take some time in Solr
anyway, so there will be no quick release of Solr based on Lucene 3.0.
