There have been several important fixes that we've backported to bobtail that users are hitting in the wild. Most notably, there was a problem with pool names with - and _ that OpenStack users were hitting, and memory usage by ceph-osd and other daemons due to the trimming of in-memory logs. This and more is fixed in v0.56.4. We recommend that all bobtail users upgrade. Notable changes include: * mon: fix bug in bringup with IPv6 * reduce default memory utilization by internal logging (all daemons) * rgw: fix for bucket removal * rgw: reopen logs after log rotation * rgw: fix multipat upload listing * rgw: don't copy object when copied onto self * osd: fix caps parsing for pools with - or _ * osd: allow pg log trimming when degraded, scrubbing, recoverying (reducing memory consumption) * osd: fix potential deadlock when 'journal aio = true' * osd: various fixes for collection creation/removal, rename, temp collections * osd: various fixes for PG split * osd: deep-scrub omap key/value data * osd: fix rare bug in journal replay * osd: misc fixes for snapshot tracking * osd: fix leak in recovery reservations on pool deletion * osd: fix bug in connection management * osd: fix for op ordering when rebalancing * ceph-fuse: report file system size with correct units * mds: get and set directory layout policies via virtual xattrs * mkcephfs, init-ceph: close potential security issues with predictable filenames There is one minor change (fix) in the output to the 'ceph osd tree --format=json' command.
