We’re happy to announce the release of Dune 3.10.0. It comes with some internal  
fixes as well as some interesting features:

- some changes in `dune describe` that will allow a better implementation of [opam-dune-lint](https://github.com/ocurrent/opam-dune-lint) to check the consistency between library and package dependencies
- more commands made available under `dune show` for a more consistent command line interface

Here is the full changelog:

## Added

- Add `dune show rules` as alias of the `dune rules` command. (#8000, @Alizter)

- Add `dune show installed-libraries` as an alias of the `dune installed-libraries` command. (#8135, @Alizter)

- Add `dune build --dump-gc-stats FILE` argument to dump garbage collection stats to a named file. (#8072, @Alizter)

- Add `dune describe package-entries` to print all package entries (#7480, @moyodiallo)

## Fixed

- Fix `%{deps}` to expand properly in `(cat ...)` when containing 2 or more items. (#8196, @Alizter)

- Fix the `severity` of error messages sent over RPC which was missing. (#8193, @Alizter)

- Fix bug with ppx and Reason syntax due to missing dependency in sandboxed action (#7932, fixes #7930, @Alizter)

## Changed

- Improve `dune describe external-lib-deps` by adding the internal dependencies for more information. (#7478, @moyodiallo)

- Re-enable background file digests on Windows. The files are now open in a way that prevents race condition around deletion. (#8262, fixes #8268, @emillon)
