[ANNOUNCE] Apache Lucene 3.5.0 released
November 27 2011, Apache Lucene™ 3.5.0 available
The Lucene PMC is pleased to announce the release of Apache Lucene 3.5.0.
Apache Lucene is a high-performance, full-featured text search engine
library written entirely in Java. It is a technology suitable for nearly
any application that requires full-text search, especially cross-platform.
This release contains numerous bug fixes, optimizations, and
improvements, some of which are highlighted below. The release
is available for immediate download at:
http://www.apache.org/dyn/closer.cgi/lucene/java (see note below).
See the CHANGES.txt file included with the release for a full list of
details.
Lucene 3.5.0 Release Highlights:
* Added a very substantial (3-5X) RAM reduction required to hold the
terms index on opening an IndexReader. (LUCENE-2205)
* Added IndexSearcher.searchAfter which returns results after a
specified ScoreDoc (e.g. last document on the previous page) to
support deep paging use cases. (LUCENE-2215)
* Added SearcherManager to manage sharing and reopening IndexSearchers
across multiple search threads. Underlying IndexReader instances are
safely closed if not referenced anymore. (LUCENE-3445, LUCENE-3558)
* Added SearcherLifetimeManager which safely provides a consistent
view of the index across multiple requests (e.g. paging/drilldown).
(LUCENE-3558, LUCENE-3486)
* Renamed IndexWriter.optimize to forceMerge to discourage use of
this method since it is horribly costly and rarely justified
anymore. (LUCENE-3439)
* Added NGramPhraseQuery that speeds up phrase queries 30-50%
when n-gram analysis is used. (LUCENE-3426)
* Added a new reopen API (IndexReader.openIfChanged) that
returns null instead of the old reader if there are no changes
in the index. (LUCENE-3464)
* Improvements to vector highlighting: support for more queries
such as wildcards and boundary analysis for generated snippets
(LUCENE-1824, LUCENE-1889)
* IndexSearcher and IndexReader now perform additional checks to
throw AlreadyClosedExceptions if searches are performed on a
closed IndexReader. Performing searches on already closed reader
can cause JVM crashes when invalid memory mapped files are
referenced.
* Several bugfixes, including a bug where closing an NRT reader
after the writer was closed was incorrectly invoking the
DeletionPolicy. See CHANGES.txt entries for full details.
Note: The Apache Software Foundation uses an extensive mirroring network for
distributing releases. It is possible that the mirror you are using may not
have replicated the release yet. If that is the case, please try another
mirror. This also goes for Maven access.
Happy searching,
Apache Lucene/Solr Developers

I checked again, IW.optimize() is still there. So no backwards breaks at all. But reopen is also there, so the backwards breaks are still wrongly documented. I'll fix in the changes.txt

Damned! I don't think we need to release this again but I think we
should fix it in the branch[es] and the website. I can build the
changes again and update the website if nobody objects...

Thanks, great work!
When reviewing the Changes.html again I found out that we mixed up backwards changes, sorry a little bit too late :(
- IR.optimize() was completely removed and not deprecated, but is *not* listed in backwards breaks - instead in API changes only
- IR.reopen() was deprecated but not removed, but is listed in backwards breaks - should be in API changes
