Subject: [RELEASE] Apache Cassandra 1.0 released

The Cassandra team is very pleased to announce the release of Apache Cassandra version 1.0.0.
Cassandra 1.0.0 is a new major release that build upon the awesomeness of previous versions
and adds numerous improvements[1,2], amongst
which:
  - Compression of on-disk data files (SSTables), with checksummed blocks to
    protect against bitrot[4].
  - Improvements to memory management through off-heap caches, arena
    allocation and automatic self-tuning, for less GC pauses and more
    predictable performances[5].
  - Better disk-space management: better control of the space taken by commit
    logs and immediate deletion of obsolete data files.
  - New optional leveled compaction strategy with more predictable performance
    and fixed sstable size[6].
  - Improved hinted handoffs, leading to less need for read repair for
    better read performances.
  - Lots of improvements to performance[7], CQL, repair, easier operation,
    etc[8]...

And as is the rule for some time now, rolling upgrades from previous versions are supported,
so there is nothing stopping you to get all those goodies right now!

Both source and binary distributions of Cassandra 1.0.0 can be downloaded at:

 http://cassandra.apache.org/download/

Or you can use the debian package available from the project APT repository[3] (you will need
to use the 10x series).

The download page also link to the CQL drivers that, from this release on, are maintained
out of tree[9].


That's all folks!
