+## [4.0.0a2] - 2025-11-11
+
+## 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](https://github.com/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.
