### [`v9.6.1`](https://redirect.github.com/facebook/rocksdb/releases/tag/v9.6.1): RocksDB 9.6.1
#### 9.6.1 (2024-08-24)
##### Bug Fixes
- Fix correctness of MultiGet across column families with user timestamp.
#### 9.6.0 (2024-08-19)
##### New Features
- \*Best efforts recovery supports recovering to incomplete Version with a clean seqno cut that presents a valid point in time view from the user's perspective, if versioning history doesn't include atomic flush.
- New option `BlockBasedTableOptions::decouple_partitioned_filters` should improve efficiency in serving read queries because filter and index partitions can consistently target the configured `metadata_block_size`. This option is currently opt-in.
- Introduce a new mutable CF option `paranoid_memory_checks`. It enables additional validation on data integrity during reads/scanning. Currently, skip list based memtable will validate key ordering during look up and scans.
##### Public API Changes
- Add ticker stats to count file read retries due to checksum mismatch
- Adds optional installation callback function for remote compaction
##### Behavior Changes
- There may be less intra-L0 compaction triggered by total L0 size being too small. We now use compensated file size (tombstones are assigned some value size) when calculating L0 size and reduce the threshold for L0 size limit. This is to avoid accumulating too much data/tombstones in L0.
##### Bug Fixes
- \*Make DestroyDB supports slow deletion when it's configured in `SstFileManager`. The slow deletion is subject to the configured `rate_bytes_per_sec`, but not subject to the `max_trash_db_ratio`.
- Fixed a bug where we set unprep_seqs\_ even when WriteImpl() fails. This was caught by stress test write fault injection in WriteImpl(). This may have incorrectly caused iteration creation failure for unvalidated writes or returned wrong result for WriteUnpreparedTxn::GetUnpreparedSequenceNumbers().
- Fixed a bug where successful write right after error recovery for last failed write finishes causes duplicate WAL entries
- Fixed a data race involving the background error status in `unordered_write` mode.
- \*Fix a bug where file snapshot functions like backup, checkpoint may attempt to copy a non-existing manifest file. [#12882](https://redirect.github.com/facebook/rocksdb/issues/12882)
- Fix a bug where per kv checksum corruption may be ignored in MultiGet().
- Fix a race condition in pessimistic transactions that could allow multiple transactions with the same name to be registered simultaneously, resulting in a crash or other unpredictable behavior.
