Bug fixes

• https://github.com/qdrant/qdrant/pull/1208 - fix error on collection replication factor and write consistency factor update
• https://github.com/qdrant/qdrant/pull/1198 - handle zero-length vectors with cosine distance - skip normalization and store vector as-is, in this case if will have 0 score with all other vectors

Improvements

• https://github.com/qdrant/qdrant/pull/1184 - enable HTTP compression middleware
• https://github.com/qdrant/qdrant/pull/1200 - ensures read-after-write consistency in case of replica failure and if requests are going to the same peer.
