We're glad to announce the fifth bug fix release of Mimic v13.2.X stable
release series. We recommend that all users upgrade.

Notable Changes

* This release fixes the pg log hard limit bug that was introduced in
  13.2.2, https://tracker.ceph.com/issues/36686. A flag called
  `pglog_hardlimit` has been introduced, which is off by default. Enabling
  this flag will limit the length of the pg log. In order to enable
  that, the flag must be set by running `ceph osd set pglog_hardlimit`
  after completely upgrading to 13.2.2. Once the cluster has this flag
  set, the length of the pg log will be capped by a hard limit. Once set,
  this flag *must not* be unset anymore. In luminous, this feature was
  introduced in 12.2.11. Users who are running 12.2.11, and want to
  continue to use this feature, should upgrade to 13.2.5 or later.

* This release also fixes a CVE on civetweb, CVE-2019-3821 where SSL file
  descriptors were not closed in civetweb in case the initial negotiation fails.

* There have been fixes to RGW dynamic and manual resharding, which no longer
  leaves behind stale bucket instances to be removed manually. For finding and
  cleaning up older instances from a reshard a radosgw-admin command `reshard
  stale-instances list` and `reshard stale-instances rm` should do the necessary
  cleanup. These commands should *not* be used on a multisite setup as the stale
  instances may be unlikely to be from a reshard and can have consequences. In
  the next version the admin CLI will prevent this command to be run on a
  multisite cluster, however for the current release users are urged not to
  use the delete command on a multisite cluster.
