Delete objects only after a SYNC during rebalance in the non-immediate_commit mode
...
Previously OSDs could commit deletes before writes during recovery or rebalance
in the "lazy fsync" (immediate_commit=off) mode which could result in lost objects

Preserve previous PG history when changing PG distribution
...
Fixes incorrect PG history in case when a new rebalance is started
before the finish of the previous one which could make primary OSDs unable
to locate some objects on some secondaries.

Use real pg configuration instead of the "last clean" one for generating PG history
...
Basically fixes the bug introduced in 0.5.7 where an rebalance interrupted
by the monitor could result in forgetting objects moved to the new place

Fix PG count change procedure
...
In previous versions PG histories were calculated incorrectly during
PG count change which led to objects being lost on OSDs not in PG's osd set.

Fix PG optimizer removing PGs without adding new ones
...
This happened when the distribution was already valid for the current OSD tree,
but didn't use all OSDs. For example, OSDs 1 2 3 and all PGs equal to [ 1, 2 ]
remained unchanged.

Update the license to VNPL 1.1
...
VNPL 1.1 is slightly reworded to make it clear that proprietary software
interacting with Vitastor and providing some kind of service to end users isn't
a "Proxy Program" if it's not specially designed to be used with Vitastor.
For example, Windows OS running in a virtual machine stored in a Vitastor
cluster clearly isn't.
