- Major changes to `homebrew` module
`homebrew.cleanup` was renamed to `homebrew.onActivation.cleanup`.
`homebrew.autoUpdate` was renamed to `homebrew.onActivation.autoUpdate`.
`homebrew.onActivation.upgrade` was added, and the default behavior of the
module was changed to not upgrade installed formulae and apps.
`homebrew.global.autoUpdate` was added.
`homebrew.global.noLock` was replaced with `hombrew.global.lockfiles`.
`homebrew.caskArgs` submodule was added for configuring arguments to be used
for all casks.
`homebrew.{taps,brews,casks}` were reimplemented as lists of submodules,
instead of lists of strings, with well documented options for all available
arguments for these Brewfile entry types, while preserving backwards
compatibility with the previous implementation.
2022-08-14
- nix module updated to bring it back in sync with it's NixOS counterpart
It should now be much more fiesable to share code for this module between
