Qdrant v0.11 introduces significant updates, including replication support for enhanced high availability and distributed deployment, which allows for horizontal scaling of collections and cluster throughput, ensuring performance and reliability with large data volumes. The release also features a new administration API enabling the disabling of write operations to prioritize search availability and mitigate memory usage issues. Additionally, an exact search parameter has been added to enforce precise vector searches, aiding in HNSW configuration validation, and the info API now reports indexed payload points for verification. While the update maintains backward compatibility with v0.10.5 storage on single-node deployments, it is not compatible with previous versions in distributed setups due to necessary changes for the replica set implementation, although client compatibility with the v0.10.x service is retained.
