 # Rocksdb Change Log
 > NOTE: Entries for next release do not go here. Follow instructions in `unreleased_history/README.txt`
 
+## 9.5.0 (07/19/2024)
+### Public API Changes
+* Introduced new C API function rocksdb_writebatch_iterate_cf for column family-aware iteration over the contents of a WriteBatch
+* Add support to ingest SST files generated by a DB instead of SstFileWriter. This can be enabled with experimental option `IngestExternalFileOptions::allow_db_generated_files`.
+
+### Behavior Changes
+* When calculating total log size for the `log_size_for_flush` argument in `CreateCheckpoint` API, the size of the archived log will not be included to avoid unnecessary flush
+
+### Bug Fixes
+* Fix a major bug in which an iterator using prefix filtering and SeekForPrev might miss data when the DB is using `whole_key_filtering=false` and `partition_filters=true`.
+* Fixed a bug where `OnErrorRecoveryBegin()` is not called before auto recovery starts.
+* Fixed a bug where event listener reads ErrorHandler's `bg_error_` member without holding db mutex(#12803).
+* Fixed a bug in handling MANIFEST write error that caused the latest valid MANIFEST file to get deleted, resulting in the DB being unopenable.
+* Fixed a race between error recovery due to manifest sync or write failure and external SST file ingestion. Both attempt to write a new manifest file, which causes an assertion failure.
+
+### Performance Improvements
+* Fix an issue where compactions were opening table files and reading table properties while holding db mutex_.
+* Reduce unnecessary filesystem queries and DB mutex acquires in creating backups and checkpoints.
+
 ## 9.4.0 (06/23/2024)
 ### New Features
 * Added a `CompactForTieringCollectorFactory` to auto trigger compaction for tiering use case.
