Vitastor 2.2.2 released
- Fix a bug introduced in 2.2.0 - pg_locks weren’t disabled for pools without local_reads correctly which could lead to inactive pools during various operations
- Fix an old bug where OSDs could send sub-operations to incorrect peer OSDs when their connections were stopped and reestablished quickly, in 2.2.0 it was usually leading to “sequencing broken” messages in OSD logs
- Fix debug use_sync_send_recv mode

Vitastor 2.2.0 released
New features
- Localized read support for multi-datacenter setups.
- io_uring-based zero-copy send support - read the instruction carefully for optimal performance!
- Improve and speedup data distribution, especially in cases of very large hosts (100 OSD+). Previously, PG optimization speed depended on the number of OSDs, now it only depends on the number of failure domains. Distribution over specific OSDs is now also more even and becomes strictly more even when you increase the number of PGs.
- Add a very interesting instruction to change NFS_MAX_FILE_IO_SIZE
- Check operation sequencing and stop connections when it breaks - should help catch some very rare RDMA packet loss problems.
vitastor-cli rm-osdnow refuses to remove OSDs which are still up and suggests to usevitastor-disk purge.- Allow removal of direntries referring non-existent inodes in VitastorFS.

First release of Vitastor S3
The moment has come - Vitastor S3 implementation based on Zenko CloudServer is finally released.
Key differences from the prototype:
- Volume defragmentation is implemented;
- Volume metadata may now be stored in the same MongoDB as object metadata, not just in VitastorKV;
- Tests for the Vitastor S3 backend added;
- S3 is now packaged in a convenient Docker build.

Vitastor 2.0.0 released
No breaking features, it’s 2.0.0 just because it includes S3 and because there are already too many 1.x releases :).
