    v0.56.7 Bobtail released

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 […]

    This is an imporant point release for Dumpling.

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 […]

    v0.67-rc2 Dumpling release candidate

    Hi everyone, We have a release candidate for v0.67 Dumpling! There are a handful of remaining known issues (which I suppose means it is technically *not* an actual candidate for the final release), but for the most part we are happy with the stability so far, and encourage anyone with test clusters to give it […]
