 ## [Unreleased]
-- Support for range search in HNSW and Fast scan IVF.
+
+## [1.8.0] - 2024-02-27
+### Added
+- Added a new conda package faiss-gpu-raft alongside faiss-cpu and faiss-gpu
+- Integrated IVF-Flat and IVF-PQ implementations in faiss-gpu-raft from RAFT by Nvidia [thanks Corey Nolet and Tarang Jain]
+- Added a context parameter to InvertedLists and InvertedListsIterator
+- Added Faiss on Rocksdb demo to showing how inverted lists can be persisted in a key-value store
+- Introduced Offline IVF framework powered by Faiss big batch search
+- Added SIMD NEON Optimization for QT_FP16 in Scalar Quantizer. [thanks Naveen Tatikonda]
+- Generalized ResultHandler and supported range search for HNSW and FastScan
+- Introduced avx512 optimization mode and FAISS_OPT_LEVEL env variable [thanks Alexandr Ghuzva]
+- Added search parameters for IndexRefine::search() and IndexRefineFlat::search()
+- Supported large two-level clustering
+- Added support for Python 3.11 and 3.12
+- Added support for CUDA 12
+
+### Changed
+- Used the benchmark to find Pareto optimal indices. Intentionally limited to IVF(Flat|HNSW),PQ|SQ indices
+- Splitted off RQ encoding steps to another file
+- Supported better NaN handling
+- HNSW speedup + Distance 4 points [thanks Alexandr Ghuzva]
+
+### Fixed
+- Fixed DeviceVector reallocations in Faiss GPU
+- Used efSearch from params if provided in HNSW search
+- Fixed warp synchronous behavior in Faiss GPU CUDA 12
+
