autoCommit=false was already introduced in 2.2.0, so also people who are
upgrading from 2.2.0 might be at risk. But I can still mention that
autoCommit is a quite new feature and that by default autoCommit=true is
used. Attached an updated version of the draft.



Release 2.3.1 of Lucene Java is now available!

This release contains fixes for serious bugs in 2.3.0 that could cause
index corruptions in autoCommit=false mode. The autoCommit option was
added to IndexWriter with release 2.2.0. If not explicitly set to false,
the IndexWriter runs in autoCommit=true mode.

2.3.1 does not contain any new features, API or file format changes,
which makes it fully compatible to 2.3.0.

We would like to encourage everyone who currently uses Lucene Java 2.3.0
to upgrade to 2.3.1 to prevent possible index corruptions!

Binary and source distributions are available at

Lucene artifacts are also available in the Maven2 repository at
