0.90.3 Released

The Elasticsearch dev team is pleased to announce the release of Elasticsearch 0.90.3, which is based on Lucene 4.4. You can download it here.

Noticeable changes in 0.90.3 include performance improvements to the has_child query, and improved cluster stability and handling of large cluster states (many indices/shards/aliases). A full list of changes can be found here.

An exciting new experimental feature that we back ported to 0.90.3 is a new type of suggester called completion. This is a real-time, prefix oriented suggestion that supports updates in real time while also maintaining an efficient (speed and resource) data structure to provide extreme low latency suggestions cases, specifically as-you-type ones. A blog post describing this exciting new features with actual use cases will be posted shortly.

Please download and use 0.90.3, and let us know what you think.

Note: If you use the analysis, mapper attachments or cloud plugins, you'll need to update to the newest version of the plugin to be compatible with the new 0.90.3 release.
