Lucene maintains compatibility with earlier stable release index
versions, and to some extent transparently upgrades them.
But there is no guaranteed compatibility between different
in-development indexes.
E.g. 3.2 reads 3.1 indexes and upgrades them, but 3.2-dev-snapshot-10
(while happily handling 3.1) may fail reading 3.2-dev-snapshot-8
index, as they have the same version tag, yet different formats.

Under LUCENE-2720 the index format of both trunk and 3x has changed. You
should re-index any indexes created with either of these code streams.
Does the 3x refer to the 3.x development branch?
I.e. For those of using the stable 3.x release of Lucene, will
a future 3.x release require rebuilding indexes?
