This update provides ownCloud 6 for EL6. Ideally I'd rather actually do ownCloud 5, but I don't think I can go back, since OC 6 was already submitted. Upgrading from 4.5 directly to 6 may not work: if you have a 4.5 install you wish to upgrade I would recommend first upgrading to ownCloud 5 from my repository at https://www.happyassassin.net/temp/oc5_repo (wget https://www.happyassassin.net/temp/oc5_repo/oc5.repo in /etc/yum.repos.d/ ).
However you upgrade, please back up your user data, ownCloud configuration and database before running the upgrade.
IMPORTANT NOTE for those using the PostgreSQL database backend: ownCloud 6 requires PostgreSQL 9.0 or higher. The official EL 6 repositories contain only 8.4. You will need to use a remote server or third-party PostgreSQL 9.0 packages. If this presents a major problem for you, please get in touch, and we can look into possibilities, but I'm figuring probably most folks will have moved up to 9.x some way or another.
ownCloud 4.5 is no longer supported upstream and is known to have security vulnerabilities: a major version upgrade is required to keep the package maintainable.
The new ownCloud requires a newer SabreDAV, so this update provides the latest SabreDAV 1.7. This is an API-incompatible update to SabreDAV 1.6, but it cannot be avoided, and there is no package other than ownCloud which depends on SabreDAV in the official or EPEL repositories.
The changes between ownCloud 4.5 and 6.0 are far too numerous to list specifically: see the upstream site and the package changelog for more details.
