On April 26, Elastic published Elasticsearch version 2.3.2.
Version 2.3.2 contains a number of bug fixes, including an issue when selecting concrete indices during a snapshot restore. If, when restoring a snapshot and an index not in the snapshot is specified, another index contained within the snapshot would be selected to restore. This bug is known to exist on version 1.7.
It also contains a fix for a bug when using extended_stats_bucket pipeline aggregations, where the sigma variable was not serialized in
ExtendedStatsBucketPipelineAggregator. There are several more bug fixes and changes that can be read in full, via the release notes.
