## New Features 🎉

### Match Query

Introducing a new query builder function: [`paradedb.match`](https://github.com/paradedb/paradedb/tree/main/docs/legacy/advanced/full-text/match.mdx). Similar to Elasticsearch's match query,
`paradedb.match` is meant to be the standard query function for full text search, allowing for
custom tokenizers and fuzzy matching. It supersedes the `paradedb.fuzzy_phrase` query.

### JSON Term Set

`paradedb.term_set` now supports JSON fields.

## Performance Improvements 🚀

- Modified the block storage layout for faster reads. This breaking change necessitates existing indexes to be
  recreated.
- Significantly improved `VACUUM` times when the table contains updated or deleted rows - `VACUUM`ing one million
  updated rows went from 20 minutes to 0.8 seconds.

## Stability Improvements 💪

- Fixed a bug where datetime values with sub-second precision were truncated to second precision.
- Fixed an issue where `VACUUM`s could not receive `SIGINT`s.
- Fixed concurrency issues around concurrent `UPDATE`, `VACUUM`, and parallel custom scans.

## New Contributors 👋

- [AdamGS](https://github.com/AdamGS) made their first contribution in [2146](https://github.com/paradedb/paradedb/pull/2146).
