| 2.4.10         | 2.4.6              | 2.4.3            | 2.4.6               |

Milvus 2.4.10 introduces significant improvements in functionality and stability. Key features include support for upsert operations on AutoID-enabled collections, partial collection loading capabilities, and various memory-mapped (MMAP) configurations to optimize memory usage. This release also addresses several bugs causing panics, core dumps, and resource leaks. We recommend upgrading to take full advantage of these improvements.
