    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 […]

    v0.69 released

    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 […]

    Our first development release after Dumpling has arrived!  It includes a lot of small cleanups and documentation improvements, as well as the first blueprint from the Emperor CDS to land (support for ZFS).  There are also new sample implementations for RADOS classes (cls_hello) and a sample librados application (hello_world) to help developers and users get […]

    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 […]

    v0.67.2 Dumpling released

    This is an imporant point release for Dumpling. Most notably, it fixes a problem when upgrading directly from v0.56.x Bobtail to v0.67.x Dumpling (without stopping at v0.61.x Cuttlefish along the way). It also fixes a problem with the CLI parsing of the CEPH_ARGS environment variable (which causes problems with older releases of OpenStack), high CPU […]

    v0.61.8 Cuttlefish released

    We’ve made another point release for Cuttlefish.  This release contains a number of fixes that are generally not individually critical, but do trip up users from time to time, are non-intrusive, and have held up under testing. Notable changes include: librados: fix async aio completion wakeup librados: fix aio completion locking librados: fix rare deadlock […]

    v0.67.1 Dumpling released

    This is a bug fix release for Dumpling that resolves a problem with the librbd python bindings (triggered by OpenStack) and a hang in librbd when caching is disabled. Notable changes: librados, librbd: fix constructor for python bindings with certain usages (in particular, that used by OpenStack) librados, librbd: fix aio_flush wakeup when cache is […]
