+Milvus 2.4.20 addresses several critical issues, including fixing mmap for sparse index, resolving the failure to parse the correct database name when altering collection fields, and preventing deadlocks in multiple compaction tasks within the scheduler. Additionally, this version introduces an enhancement that allows adjustment of the system limit for maximum varchar length through a configuration item in the YAML file. We highly recommend upgrading to this version for improved stability and reliability.
