# Unstable

When upgrading from a previous release, please be aware of the following incompatible changes:

- `wmiiSnap` has been replaced with `wmii_hg`, but `services.xserver.windowManager.wmii.enable` has been updated respectively so this only affects you if you have explicitly installed `wmiiSnap`.

- `wmiimenu` is removed, as it has been removed by the developers upstream. Use `wimenu` from the `wmii-hg` package.
