- `neofs-cli` buffer for object put increased from 4 KiB to 3 MiB (#2243)
- Expired locked object is available for reading (#56)
- Initialize write-cache asynchronously (#32)
- Update system attribute names (#159)
### Fixed
- Increase payload size metric on shards' `put` operation (#1794)

New config field `object.delete.tombstone_lifetime` allows to set tombstone lifetime
more appropriate for a specific deployment.
Use `__SYSTEM__` prefix for system attributes instead of `__NEOFS__`
(existed objects with old attributes will be treated as before, but for new objects new attributes will be used).
