The Cassandra team is very pleased to announce the release of Apache Cassandra version 1.1.0. Cassandra 1.1.0 is a new major release for the Apache Cassandra distributed database. This version adds numerous improvements[1,2], amongst which: - Schema updates have been reworked and conflict from concurrent updates are now automatically resolved[4] - It introduces a new major revision of the Cassandra Query Language: CQL v3.0[5], even though CQL 2.0 is still supported and the default. - Updates within a row are now made in isolation[6]. - Finer-grained control over data directories placement[7]. - Global row and key caches for easier configuration - And much more...
And as is the rule for some time now, rolling upgrades from previous versions are supported, but make sure to have a look at the release notes[2] before upgrading. Both source and binary distributions of Cassandra 1.1.0 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 11x series).
