+- `fzf` : `fzf-share`

 - `xxd` has been moved from `vim` default output to its own output to reduce closure size. The canonical way to reference it across all platforms is `unixtools.xxd`.
 
-- `programs.fzf.keybindings` and `programs.fzf.fuzzyCompletion` got replaced by `programs.fzf.enable` as shell-completion is included in the fzf-binary now there is no easy option to load completion and keybindings separately. Please consult fzf-documentation on how to configure/disable certain keybindings.
