v2.0.1

Release date: 2022-02-23

Compatibility

Milvus 2.0.1 is a minor bug-fix version of Milvus 2.0. The key progress of Milvus 2.0.1 includes that, first, the execution engine of Milvus knowhere was separated from the Milvus repository and moved to a new one - milvus-io/knowhere, and, second, supports were enabled for Milvus to be compiled across multiple platforms. We fixed a few critical issues that cause query node crash, index building failure, and server hang. The default dependency of Golang is upgraded to solve memory usage issues. We also upgrade the default dependency of Pulsar to solve the log4j security issue.
