[ANNOUNCE] Apache Solr 4.2 released
March 2013, Apache Solr™ 4.2 available
The Lucene PMC is pleased to announce the release of Apache Solr 4.2
Solr is the popular, blazing fast, open source NoSQL search platform
from the Apache Lucene project. Its major features include powerful
full-text search, hit highlighting, faceted search, dynamic
clustering, database integration, rich document (e.g., Word, PDF)
handling, and geospatial search. Solr is highly scalable, providing
fault tolerant distributed search and indexing, and powers the search
and navigation features of many of the world's largest internet sites.
Solr 4.2 is available for immediate download at:
http://lucene.apache.org/solr/mirrors-solr-latest-redir.html
See the CHANGES.txt file included with the release for a full list of details.
Solr 4.2 Release Highlights:
* A read side REST API for the schema. Always wanted to introspect the
schema over http? Now you can. Looks like the write side will be
coming next.
* DocValues have been integrated into Solr. DocValues can be loaded up
a lot faster than the field cache and can also use different
compression algorithms as well as in RAM or on Disk representations.
Faceting, sorting, and function queries all get to benefit. How about
the OS handling faceting and sorting caches off heap? No more tuning
60 gigabyte heaps? How about a snappy new per segment DocValues
faceting method? Improved numeric faceting? Sweet.
* Collection Aliasing. Got time based data? Want to re-index in a
temporary collection and then swap it into production? Done. Stay
tuned for Shard Aliasing.
* Collection API responses. The collections API was still very new in
4.0, and while it improved a fair bit in 4.1, responses were certainly
needed, but missed the cut off. Initially, we made the decision to
make the Collection API super fault tolerant, which made responses
tougher to do. No one wants to hunt through logs files to see how
things turned out. Done in 4.2.
* Interact with any collection on any node. Until 4.2, you could only
interact with a node in your cluster if it hosted at least one replica
of the collection you wanted to query/update. No longer - query any
node, whether it has a piece of your intended collection or not and
get a proxied response.
* Allow custom shard names so that new host addresses can take over
for retired shards. Working on Amazon without elastic ips? This is for
you.
* Lucene 4.2 optimizations such as compressed term vectors.
Solr 4.2 also includes many other new features as well as numerous
optimizations and bugfixes.
Please report any feedback to the mailing lists
(http://lucene.apache.org/solr/discussion.html)
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,
Lucene/Solr developers

Nice :)
Seems that this solves the main use case I have for core SWAP (was
missing in SolrCloud) : https://issues.apache.org/jira/browse/SOLR-3866
I am eager to try this, any doc/wiki about collection aliasing before I
start ?

The "Upgrading from Solr 4.1.0" section of the 4.2.0 CHANGES.txt says:
"(No upgrade instructions yet)"
To me that's not the same as no need to do anything. I think the doc
should be updated with either specific instructions or states 4.2.0 is
backward compatible with 4.1.0 so there is no need to do anything.

See CHANGES.txt, but 4.2 is pretty much bug fixing, I don't think there's
anything special you need to do.
