How come this new version is bundled with rails and why is there no .war
output format?
I wanted a simple drop in replacement for my current war :(

What performance improvements does 4.x have over 3.1?
Ah... well, many - take a look at the CHANGES.txt.
reindexing cycles are long (indexes tend to stay around)
then 3.1 is a safer bet. If you need a dozen or so new
exciting features (e.g. results grouping) or top
performance, or if you need LucidWorks with Click and other
goodies, then use 4.x and be prepared for an occasional full
reindex.
So using 4.x would require occasional full reindex but using 3.1
would not? Could you explain? I thought 4.x comes with NRT indexing.
So why is full reindex necessary?
Well, so long as you don't want to upgrade then of course, index
format is stable and you can manage it incrementally. But in case of
an upgrade, because in 4.x index format is not stable - if you upgrade
to a newer Lucene / LucidWorks of 4.x vintage then it may be the case
that even though indexes before and after upgrade are of 4.x vintage
they are still incompatible.
At some point there may be tools to transparently convert indexes from
one 4.x to another 4.x format, but they are not there yet.
