New features:
- Data and metadata checksums!
- Metadata checksums are always used with new disk format
- Data checksums can be turned on with --data_csum_type crc32c for new OSDs
- Checksum block size can be configured
- inmemory_metadata now also affects keeping checksums in memory
- Linux page cache I/O caching support which can be enabled separately for
data, metadata (including checksums) and journal (O_SYNC instead of O_DIRECT)
- Details [here](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/config/layout-osd.en.md#data_csum_type)
- Backwards compatibility is preserved, you can use new OSDs with old disks
Release also includes bug fixes from [0.9.6](https://git.yourcmc.ru/vitalif/vitastor/releases/tag/v0.9.6).
0.9.6 is moved to "-oldstable" repositories and will be available for some additional time.
