Milvus 2.4.14 addresses a critical issue from version 2.4.13 that could cause collection information to be lost after `snapshotKV` garbage collection. It also fixed a couple of resource leaks. Additionally, this release includes numerous enhancements focused on improving stability in large-scale delete operations and compaction performance.

### Features
