5.0.4 is live!

The Zimbra Team is pleased to announce: The Zimbra Collaboration Suite version 5.0.4!

To avoid confusion with existing builds, ZCS 5.0.3 has been renamed ZCS 5.0.4
-If you are already comfortably on 5.0.3 you are all set - there is no pressing need to upgrade though it's always preferred that you do so.
-However, if you are running 5.0.3 and make use of the nginx proxy, we advise upgrading to 5.0.4 for an additional security & stability fix.

As always, we strongly encourage you to make a full backup before performing any server maintenance. Backup and Restore Articles - Zimbra :: Wiki

Some key enhancements:
Bug 9469 - ZCS Mailbox Server Proxy Alpha (REST Sharing/CalDAV/Zimbra Mobile support is under construction)
Exchange Free-Busy Interop Beta (checkout src/ZimbraServer/docs/freebusy-interop.txt & admin console 'help')
Bug 19235 - Batched indexing
Bug 20977 - Upgrade to Lucene-2.3
Bug 25091 - 5 concurrent IMAP selected folders per user is too low
Bug 6390 - Support formatted (html) signatures
Bug 10071 - Allow start/stop dates for out of office notifications
Bug 24823 - expose zimbraMailPurgeSleepInterval in Admin Console.

With this release comes a beta 64-bit Ubuntu 6.06 LTS for ZCS 5.0.4 FOSS build!
-An NE build is in the works, we just want to be certain in some fixed java quirks on 64-bit before we roll out a new platform. Your continued show of interest is valued & you can add your votes/tagged ticket requests to Bug 16666 - 64-bit Ubuntu 6.0.6 LTS build

We've also collapsed the Zimlet panel tree by default (extra loading); don't forget to checkout your zimlets folders in /opt/zimbra for some useful stuff to enable!
