v2.4.14

Release Date: October 31, 2024

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.
