Qdrant 1.9.0 - Heighten Your Security With Role-Based Access Control Support - Qdrant

Introduced granular access control via JSON Web Tokens (JWT) for Role-Based Access Control (RBAC) and Single Sign-On (SSO), enabling fine-grained permissions for users and restricting access to sensitive endpoints. Implemented a faster shard transfer method using WAL delta, reducing transfer times from hours to minutes by transmitting only differential data. Added native support for uint8 embeddings, providing 4x memory savings and ~30% speed-up in search with minimal quality loss. Also included improvements to snapshotting performance, collection info reporting, and sparse vector search performance.
