- Improved delete by expression to respect delete rate limit rules according to the matched data size instead of delete request size ([#33794](https://github.com/milvus-io/milvus/pull/33794)).
- Accelerated Bloom filter processing by submitting in batch and working in parallel ([#33870](https://github.com/milvus-io/milvus/pull/33870)).
- Enabled parallel processing for `applydelete` at the segment level ([#33841](https://github.com/milvus-io/milvus/pull/33841)).
- Printed `UseDefaultConsistency` parameter in read requests ([#33645](https://github.com/milvus-io/milvus/pull/33645)).
