[pgvector](https://github.com/pgvector/pgvector/), an open-source PostgreSQ=
L extension that provides vector similarity search capabilities, has releas=
ed [v0.7.0](https://github.com/pgvector/pgvector/releases/tag/v0.7.0). This=
new release includes many new functional and performance features for supp=
orting vector similarity search workloads in PostgreSQL.
This latest version of pgvector adds new vector types, including `halfvec` =
(2-byte floats; indexing up to 4,000 dimensions) and `sparsevec` (indexing =
up to 1,000 nonzero dimensions), and includes indexing support for binary v=
ectors using the `bit` type (indexing up to 64,000 dimensions). Additionall=
y, this release adds support for quantizing vectors using expression indexe=
s, including from 4-byte to 2-byte floats and binary quantization using `bi=
nary_quantize` function. pgvector 0.7.0 also adds new distance functions, i=
ncluding `hamming_distance` and `jaccard_distance` for `bit` vectors, and n=
ow supports HNSW indexing for L1 distance operations. pgvector 0.7.0 also i=
ncludes additional support for SIMD with CPU dispatching for Linux x86-64 a=
rchitectures.
