Our next development release v0.65 is out, with a few big changes. First and foremost, this release includes a complete revamp of the architecture for the command line interface in order to lay the groundwork for our ongoing REST management API work. The 'ceph' command line tool is now a thin python wrapper around librados. Note that this set of changes includes several small incompatible changes in the interface that tools or scripts utilizing the CLI should be aware of; these are detailed in the complete release notes. Other notable changes: * mon, ceph: huge revamp of CLI and internal admin API. (Dan Mick) * mon: new capability syntax * osd: do not use fadvise(DONTNEED) on XFS (data corruption on power cycle) * osd: recovery and peering performance improvements * osd: new writeback throttling (for less bursty write performance) (Sam Just) * osd: ping/heartbeat on public and private interfaces * osd: avoid osd flapping from asymmetric network failure * osd: re-use partially deleted PG contents when present (Sam Just) * osd: break blacklisted client watches (David Zafman) * mon: many stability fixes (Joao Luis) * mon, osd: many memory leaks fixed * mds: misc stability fixes (Yan, Zheng, Greg Farnum) * mds: many backpointer improvements (Yan, Zheng) * mds: new robust open-by-ino support (Yan, Zheng) * ceph-fuse, libcephfs: fix a few caps revocation bugs * librados: new calls to administer the cluster * librbd: locking tests (Josh Durgin) * ceph-disk: improved handling of odd device names * ceph-disk: many fixes for RHEL/CentOS, Fedora, wheezy * many many fixes from static code analysis (Danny Al-Gaaf) * daemons: create /var/run/ceph as needed The complete release notes, including upgrade notes, can be found at: http://ceph.com/docs/master/release-notes/#v0-65 We have one more sprint to go before the Dumpling feature freeze. Big items include monitor performance and stability improvements and multi-site and disaster recovery features for radosgw. Lots of radosgw has already appeard in rgw-next but these changes will not land until v0.67.
