+* 2026-08-30 Tmux shell commands are now considered UNIX utilities and need to be enabled with the user.unix_utilities tag.
 * 2026-08-23 Remove `split` and `update` from the Python function vocabulary. These are methods, not built-in Python functions, and should now be invoked with the method voice command instead (e.g. "dot split" instead of "funk split").
 * 2026-08-23 Removed deprecated Jetbrains command `action` in favour of the `please` command.
 * 2026-08-10 Change tmux split commands to match the orientation conventions we use for other applications such as VS Code and Obsidian. (PR #2290)
