The version seems to be stable after this bunch of fixes :)
- Fix delete & write operation ordering during rebalance to not lose objects in the immediate_commit=off mode
- Fix a possible crash caused by very high iodepths
- Re-distribute PG primaries over OSDs that come up after a short downtime
- Allow to specify etcd URLs for OSDs with http://, do not die with a strange error if -etcd option is missing for fio
- Fix a journal flushing deadlock which sometimes occurred in the immediate_commit=off mode
- Fix a bug where OSDs could hang if the data device filled up
- Fix an allocator bug where it was unable to allocate up to last (n%64) data device blocks
- Fix monitor crash that occurred on removal of some etcd keys
- Fix a bug where PGs could remain incomplete due to incorrect PG history with just zeroes in osd_sets
