Alice v0.3.0

December 30, 2025 in release

Announcing the release of Alice v0.3.0!

This release starts following the XDG Base Directory Specification. This means there is no longer a ~/.alice directory. Tools are installed to ~/.local/share/alice/current/bin, and Alice’s executable is installed to ~/.local/bin if using the install script.

This is a breaking change.

Migrating from earlier versions

• Delete ~/.alice.
• If you have a block in your shell config starting with # BEGIN configuration from Alice installer, remove that block.
• If you installed Alice with the installation script then run the script again.
• If you used Alice to install OCaml tools, you’ll need to reinstall those tools (run alice tools install).
• If you’ve configured a custom sandbox template with Visual Studio Code for any Alice projects, change the template based on the new LSP instructions for Visual Studio Code here.

Install Alice v0.3.0

On all platforms that support Opam, install Alice v0.3.0 with:

opam update && opam install alice.0.3.0

On Windows, Alice v0.3.0 can be installed with WinGet:

On macOS and Linux, the latest version of Alice can be installed with Homebrew:

Alternatively, on macOS and Linux, Alice v0.3.0 can be installed by running the install script:
