+Milvus 2.5.2 supports modifying the maximum length for VARCHAR columns and resolves several critical issues related to concurrency, partition drops, and BM25 stats handling during import. We highly recommend upgrading to this version for improved stability and performance.

+- Added a parameter for tuning the maximum VARCHAR length and restored the limit to 65,535. ([#38883](https://github.com/milvus-io/milvus/pull/38883))
+- Supported parameter type conversion for expressions. ([#38782](https://github.com/milvus-io/milvus/pull/38782))
+
+### Bug fixes

+- Generated the index_null_offset file only for fields that support null values. ([#38834](https://github.com/milvus-io/milvus/pull/38834))
+- Fixed the retrieve plan usage after free in the reduce phase. ([#38841](https://github.com/milvus-io/milvus/pull/38841))
+- Recognized expressions with capitalized AND and OR. ([#38928](https://github.com/milvus-io/milvus/pull/38928))
