This release fixes bugs from 2.9.0, including one serious bug whereby BooleanQuery could silently fail to retrieve certain matching documents.
There are also some minor API changes, including a Version parameter added to QueryParser and contrib Analyzers, so that version dependent defaults are consistent across classes, as well as un-deprecating of certain methods (we were too zealous in a few cases!).
Otherwise the changes are all bug fixes and documentation improvements.
This release is fully compatible with 2.9.0. We strongly recommend upgrading to 2.9.1 if you are using 2.9.0. Furthermore, because some additional APIs were deprecated in 2.9.1, to ensure a clean ("JAR drop in") upgrade to 3.0 you'll need to ensure your code compiles against 2.9.1 without deprecation warnings.
See CHANGES for details.
Binary and source distributions are available here.
Maven artifacts are available here.
