    v0.70 released

    Another development release is out.  Our timing on these has been slightly erratic.  As a result, this one has a bit less stuff than 0.69 did or 0.71 will.  The highlights are some rgw and mon fixes, and the architecture detection for enabling the optimized Intel CRC32c code is now working (which is nice: it’s […]

    Our v0.69 development release of Ceph is ready!  The most notable user-facing new feature is probably improved support for CORS in the radosgw.  There has also been a lot of new work going into the tree behind the scenes on the OSD that is laying the groundwork for tiering and cache pools.  As part of […]

    v0.56.7 Bobtail released

    We have another bugfix update for bobtail. Most of these fixes have been sitting in the bobtail branch (and were run by various users) for some time now. The newest patches fix a problem with multi-delete on rgw. We recommend that production bobtail clusters upgrade, especially if they are using the radosgw. Notable changes: ceph-fuse: create finisher flags after […]
