It is my pleasure to announce a new release of Menhir. The main change is improved parser construction time in `--table` mode.

- The table back-end uses a new table compression algorithm.

To install this release, please type:

```auto
opam update && opam install menhir.20250903

```

Happy parsing,  
François.

Thanks.

Is there a reason why the release process (commit 6d38bfb2224a3414b0f07f6a5493b831d4c4d4ea) removes the CHANGES.md file? Commit 0adb78e6e139aabfb3721bed7b64d5ae599dbe34 probably went too far IMHO.

The release process creates a “release branch” which contains just the files that are needed to install Menhir.
