### New Features ### New Features
* Added new ChecksumType kXXH3 which is faster than kCRC32c on almost all x86\_64 hardware. * Added new ChecksumType kXXH3 which is faster than kCRC32c on almost all x86\_64 hardware.
* Added a new online consistency check for BlobDB which validates that the number/total size of garbage blobs does not exceed the number/total size of all blobs in any given blob file.
### Bug Fixes ### Bug Fixes
* Prevent a `CompactRange()` with `CompactRangeOptions::change_level == true` from possibly causing corruption to the LSM state (overlapping files within a level) when run in parallel with another manual compaction. Note that setting `force_consistency_checks == true` (the default) would cause the DB to enter read-only mode in this scenario and return `Status::Corruption`, rather than committing any corruption. * Prevent a `CompactRange()` with `CompactRangeOptions::change_level == true` from possibly causing corruption to the LSM state (overlapping files within a level) when run in parallel with another manual compaction.
