Elasticsearch 0.90.5 Released

The Elasticsearch dev team are pleased to announce the release of Elasticsearch 0.90.5, which is based on Lucene 4.4. You can download it here.

We released 0.90.4 yesterday with great expectations, and a few hours later had our expectations dashed by a silly bug in the plugin install script, which installed site plugins (e.g. head, bigdesk, paramedic) incorrectly. We apologize for that. That bug has been fixed and we've added the appropriate tests.

However, that is not all. Things move fast in the Elasticsearch world, so we've taken advantage of this quick release to fix a few other bugs:

  • Elasticsearch startup script doesn't work from directory with spaces in path #3712
  • A problem with sorting nested documents with score_mode: avg #3706
  • Alias filters were not being applied when indices were specified using a wildcard * #3677

Windows Support

And finally, an enhancement for those of you using Elasticsearch on Windows: we have added support for running Elasticsearch as a service on Windows (see #3716), via the service.bat script. You can now do:

> service.bat
Usage: service.bat install|remove|start|stop|manager [SERVICE_ID]

> service install
Installing service      :  'elasticsearch-service-x64'
Using JAVA_HOME (64-bit):  c:\jvm\jdk1.7
The service 'elasticsearch-service-x64' has been installed.

> service start
The service 'elasticsearch-service-x64' has been started

> service stop
The service 'elasticsearch-service-x64' has been stopped

> service remove
The service 'elasticsearch-service-x64' has been removed

All the details are available in the release notes. If you are not affected by any of the above issues then there is no need for you to upgrade from 0.90.4.

Thank you for your feedback on the release of 0.90.4 yesterday - it allowed us to find and fix the plugin script error quickly.
