## Summary - align the PyO3 runtime and build ABI floor with the declared Python 3.10 minimum - add a regression test that keeps both ABI features synchronized with `requires-python` ## Root cause The Python 3.10 support-floor update originally changed PyO3 to `abi3-py310`, but a later dependency update reverted both PyO3 features to `abi3-py39`. Published Windows wheels were consequently tagged `cp39-abi3` while importing `PyCMethod_New`, a stable-ABI procedure absent from CPython 3.9.0 and 3.9.1. Windows reports that mismatch as “The specified procedure could not be found” while loading `_lancedb`. Restoring `abi3-py310` makes the wheel tag and native imports agree with the package metadata and prevents future wheels from advertising unsupported Python 3.9 compatibility. ## Validation - `uv run --extra tests pytest python/tests/test_package_metadata.py -q` - `uv run --extra tests --extra dev ruff format --check .` - `uv run --extra tests --extra dev ruff check .` - `cargo fmt --all` - `cargo check --quiet -p lancedb-python` - `uvx --from maturin==1.12.4 maturin build --profile ci` (built `lancedb-0.37.1b0-cp310-abi3-manylinux_2_34_x86_64.whl`) Fixes #2051 <!-- lance-gatekeeper-fix:v1 agent=d66c984498190d2207d1c5126cba5047 generation=1 --> --------- Co-authored-by: Gatefixer <313497061+lancedb-gatefixer[bot]@users.noreply.github.com>

The ultimate multimodal data platform for AI/ML applications.
LanceDB is designed for fast, scalable, and production-ready vector search. It is built on top of the Lance columnar format. You can store, index, and search over petabytes of multimodal data and vectors with ease. LanceDB is a central location where developers can build, train and analyze their AI workloads.
Demo: Multimodal Search by Keyword, Vector or with SQL
