## v2.4.13

Release Date: October 12, 2024

| Milvus version | Python SDK version | Java SDK version | Node.js SDK version |
|----------------|--------------------|------------------|---------------------|
| 2.4.13 | 2.4.8 | 2.4.5 | 2.4.9 |

Milvus 2.4.13 introduces dynamic replica load, allowing users to adjust the number of collection replicas without needing to release and reload the collection. This version also addresses several critical bugs related to bulk importing, expression parsing, load balancing, and failure recovery. Additionally, significant improvements have been made to MMAP resource usage and import performance, enhancing overall system efficiency. We highly recommend upgrading to this release for better performance and stability.

### Features

- Dynamic replica adjustment for loaded collections ([#36417](https://github.com/milvus-io/milvus/pull/36417))
- Sparse vector MMAP in growing segment types ([#36565](https://github.com/milvus-io/milvus/pull/36565))

- Fixed a flush performance issue ([#36741](https://github.com/milvus-io/milvus/pull/36741))
- Fixed a bug with JSON expressions in "[]" ([#36722](https://github.com/milvus-io/milvus/pull/36722))
- Removed neighbors if compact target is unindexed ([#36694](https://github.com/milvus-io/milvus/pull/36694))
- Improved performance for Rocksmq when channel is full ([#36618](https://github.com/milvus-io/milvus/pull/36618))
- Fixed an issue where errors during unpinning were not deferred ([#36665](https://github.com/milvus-io/milvus/pull/36665))
- Resolved a memory leak for imported segments in the segment manager ([#36631](https://github.com/milvus-io/milvus/pull/36631))
- Skipped unnecessary health checks for query nodes in the proxy ([#36553](https://github.com/milvus-io/milvus/pull/36553))
- Fixed an overflow issue with term expressions ([#36534](https://github.com/milvus-io/milvus/pull/36534))
- Recorded node ID before assigning tasks to prevent task misallocation ([#36493](https://github.com/milvus-io/milvus/pull/36493))
- Resolved data race issues in clustering compaction ([#36499](https://github.com/milvus-io/milvus/pull/36499))
- Added a check for string array max length after type matching ([#36497](https://github.com/milvus-io/milvus/pull/36497))
- Addressed race conditions in mix or standalone mode ([#36459](https://github.com/milvus-io/milvus/pull/36459))
- Fixed segment imbalance after repeated load and release operations ([#36543](https://github.com/milvus-io/milvus/pull/36543))
- Corrected a corner case where segments couldn't be moved from a stopping node ([#36475](https://github.com/milvus-io/milvus/pull/36475))
- Updated segment info properly even if some segments were missing ([#36729](https://github.com/milvus-io/milvus/pull/36729))
- Prevented etcd transactions from exceeding the max limit in snapshot KV ([#36773](https://github.com/milvus-io/milvus/pull/36773))
