Even though we just had the nice and successful ownCloud Contributor Conference there have quite some ownCloud releases happened recently. I like to draw your attention to this for a moment, because some people seem to fail to see how active the ownCloud community actually is at the moment.
There has been the big enterprise release 9.1 on September 20th, but that of course came along with community releases which are in the focus here.
We had server release 8.0.15, server release 8.1.10, server release 8.2.8 and release 9.0.5. There are maintenance releases for the older major versions, needed to fix bugs on installations that still run on these older versions. We deliver them following this plan.
The latest and greatest server release is release 9.1.1 that has all the hardening that also went into the enterprise releases.
Aside a ton of bugfixes that you find listed in the changelog there have also been interesting changes which drive innovation. To pick just one example: The data fingerprint property. It enables the clients to detect if the server got a backup restored, and saves changes on the clients to conflict files if needed. This is a nice example of solutions which are based on feedback from enterprise customers community running ownCloud, who help with reporting problems and proposing solutions.
Talking about professional usage of ownCloud: Of course also all the server release are available as linux packages for various distributions, for example the ownCloud server 9.1.1 packages. We think that our users should not be forced to deploy from tarballs, which is error prone and not native to Linux, but have the choice to use linux packages through the distributions package management.
There also have been client releases recently: The Android client versions 2.1.1 and 2.1.2 were released with important changes for Android 7 and much more fixes, as well as iOS client versions 3.5.0 and 3.5.1. The desktop client 2.2.4 also got a regular bug fix update (Changelog).
I guess you agree that is a lot of activity shown in the ownCloud project, making sure to get the best ownCloud experience out there for the users, driven by passion for the project and professional usage in focus.
