Hi,
elasticsearch 0.15.2 has been released: [http://www.elasticsearch.org/download/2011/03/07/0.15.2.html](http://www.elasticsearch.org/download/2011/03/07/0.15.2.html).
It includes minor bug fixes and enhancements. The biggest change is much better memory usage due to more optimized logic in when a refresh is really needed. Upgrade is highly recommended.

How long does it usually take to get into the maven repo?
Cheers,
Paul.

In the 0.15.0 download page, you had in the upgrade notes:
"In order to upgrade to this version, and full cluster restart is
required. Shutdown the cluster using the cluster wide shutdown API,
upgrade the version, and start it back up."
I'm presuming this is still the case in 0.15.2 (upgrading from
0.14.2)?
