Highlights

This is an alpha release of SQLFluff 4.0 to continue verification of the rust portions of the codebase. In particular to verify version locking of pypi packages works, and testing users can verify that Rust is working easily. Rust support is still in beta, but from this release, users can install sqlfluff[rs] to get some of the parser running in rust. Current implementation is not expected to yield significant gains but we do expect that once mature that it will.

We do not recommend that users install this release except for testing and evaluation.

Big thanks to @keraion, who's been leading the way on this effort.

Additionally in this release:

  • Several rust bugfixes.
  • Dialect improvements for Snowflake, DuckDB, TSQL, Impala & Postgres.

These will be added to the changelog properly in the full 4.0.0 release.
