+| Milvus version | Python SDK version | Java SDK version    | Node.js SDK version |
+|----------------|--------------------| --------------------| --------------------|

+The release of Milvus 2.4.5 introduces several improvements and bug fixes to enhance performance, stability, and functionality. Milvus 2.4.5 simplifies sparse, float16, and bfloat16 vector search with auto-indexing, speeds up searches, deletions, and compactions with Bloom filter optimizations, and tackles data management through faster loading times and import L0 segment support. It also introduces the sparse HNSW index for efficient high-dimensional sparse data search, enhances the RESTful API with sparse float vector support, and fixes critical bugs for better stability.
+

+- Optimized some caches to reduce memory usage ([#33560](https://github.com/milvus-io/milvus/pull/33560)).
+- Abstracted execute interface for import/preimport tasks ([#33607](https://github.com/milvus-io/milvus/pull/33607)).
+- Used map PK to timestamp in buffer insert to reduce Bloom filter causes ([#33582](https://github.com/milvus-io/milvus/pull/33582)).
+- Avoided redundant meta operations during import ([#33519](https://github.com/milvus-io/milvus/pull/33519)).
+- Improved logs by logging better disk quota info, adding UseDefaultConsistency flag, and removing unnecessary logs ([#33597](https://github.com/milvus-io/milvus/pull/33597), [#33644](https://github.com/milvus-io/milvus/pull/33644), [#33670](https://github.com/milvus-io/milvus/pull/33670)).

+### Bug fixes
+
+- Fixed a bug that may cause Milvus to be unable to create AutoIndex on binary and sparse vectors ([#33867](https://github.com/milvus-io/milvus/pull/33867)).
+- Fixed a bug that may cause indexnode to retry creating index on invalid index parameters of all vectors ([#33878](https://github.com/milvus-io/milvus/pull/33878)).
