Breaking changes: • Collections created with any previous engine version are not compatible with v0.7.0 due to significant changes in payload format; re-create all collections from scratch after upgrading. https://github.com/qdrant/qdrant/releases/tag/v0.6.0 https://github.com/qdrant/qdrant/releases/tag/v0.6.0 Fri, 04 Mar 2022 11:34:19 GMT Qdrant v0.6.0 adds gRPC support for all endpoints and enriches `recommend` responses with payload and vector data. • Adds gRPC support for all endpoints, with Protobuf docs and a configuration guide to enable it. • The `recommend` endpoint can now return payload and vector alongside results. Breaking changes: • Python client users must follow migration examples at https://github.com/qdrant/qdrant_client/releases/tag/v0.6.0 — the REST API itself is compatible, but the Python client interface has changed. https://github.com/qdrant/qdrant/releases/tag/v0.5.1 https://github.com/qdrant/qdrant/releases/tag/v0.5.1 Wed, 16 Feb 2022 11:51:30 GMT Qdrant v0.5.1 adds improved error reporting in the collection info API and coordinate validation for geo payloads. • Improves error reporting in the collection info API, surfacing more detail when a collection is in a degraded or error state. • Validates geo coordinates submitted via the API, rejecting out-of-range or malformed latitude/longitude values at ingestion time. https://github.com/qdrant/qdrant/releases/tag/v0.5.0 https://github.com/qdrant/qdrant/releases/tag/v0.5.0 Thu, 03 Feb 2022 12:02:30 GMT Qdrant v0.5.0 adds UUID point IDs, filter-based deletion, per-operation endpoints, and multi-threaded optimization. • Supports `UUID` as a point ID type in addition to integer IDs. • Adds individual API endpoints for each collection and point operation (e.g. `set_payload`, separate upsert, delete, etc.) replacing the monolithic Update Collection and Update Points APIs. • Enables deleting points by filter via a dedicated endpoint. • Enables removing payload fields using filters via a dedicated endpoint. • Includes payload and vector data in search results. • Limits segment size to improve indexing performance. • Introduces multi-threaded optimizer for faster background indexing. Breaking changes: • Indexes created with versions prior to v0.5.0 are not compatible due to UUID support and configuration format changes; collections must be re-created from scratch. https://github.com/qdrant/qdrant/releases/tag/v0.4.1 https://github.com/qdrant/qdrant/releases/tag/v0.4.1 Mon, 25 Oct 2021 21:05:36 GMT Qdrant v0.4.1 lets you retrieve payload and vectors in a single search request, with field selection and exclusion. • Supports retrieving payload alongside search results in a single request, with field selection and exclusion. https://github.com/qdrant/qdrant/releases/tag/v0.3.4 https://github.com/qdrant/qdrant/releases/tag/v0.3.4 Sun, 20 Jun 2021 13:49:12 GMT Qdrant v0.3.4 adds a scroll API endpoint for paginating over filtered point sets. • Adds `scroll_points` API endpoint for paginating over collections of points with filter support. https://github.com/qdrant/qdrant/releases/tag/v0.3.0 https://github.com/qdrant/qdrant/releases/tag/v0.3.0 Thu, 03 Jun 2021 14:23:34 GMT Qdrant v0.3.0 adds filterable HNSW indexing, per-collection config via API, a query planner, and collection status indicators. • Adds filterable HNSW index: the optimizer automatically builds an HNSW index for vectors after a specified threshold, with the index taking payload fields into account for filtered searches. • Adds dynamic per-collection configuration: each collection now has individual settings that can be updated at any time via API request. • Adds a query planner that decides whether to use the HNSW index based on estimated filtering cardinality. • Adds a collection status indicator surfaced per collection. https://github.com/qdrant/qdrant/releases/tag/v0.2.0 https://github.com/qdrant/qdrant/releases/tag/v0.2.0 Tue, 06 Apr 2021 15:35:20 GMT Qdrant v0.2.0 adds payload field indexing for number and keyword types and revamps the Search API filter schema. • Adds the ability to mark a payload field as 'indexed', enabling payload indexation for `number` and `keyword` field types (geo field index is in progress). • Segments are now automatically rebuilt into MMap and indexed segments when enough vectors are stored, unlocking better performance at scale without manual intervention. • Changes the Search API `filter` schema: the `key` property moves out of the condition object (e.g. `match`) and becomes a sibling field alongside it — existing filter queries using the old nested-key layout will break. Breaking changes: • The Search API filter schema has changed: `key` is no longer nested inside the condition object (e.g. `match`). It must now be a sibling field at the same level as the condition. Existing queries with the old layout (e.g. `{"match": {"key": "city", "keyword": "London"}}`) will break and must be updated to the new layout (e.g. `{"key": "city", "match": {"keyword": "London"}}`).
