**Full Changelog**: https://github.com/tensorchord/pgvecto.rs/compare/v0.3.0-alpha.1...v0.3.0-alpha.2

Improvements

- NULL Support: `NULL` can now be safely inserted into vector columns without error. They will be skipped during `pgvecto.rs` index creation, but exist in the table. A query on a vector column will **never** return a result containing a `NULL`.
- Signal Handler Fix: Now we use `SIGQUIT` instead of `SIGHUP` to trigger a peaceful exit, since `SIGHUP` is defined as configure reload by `Postgres`.
- Upgrade Script Refine: Due to some symbol renaming, the upgrade path from `v0.1.10` to `v0.2.0` is broken. Users can now upgrade directly to `v0.2.1` if they are currently using `v0.1.10`.

v0.0.0-nightly
DO NOT use this version. Internal use only.
