+### [0.1.9] - 2024-02-06
 
+- auto complete support for `zsh` and `fish`; Run `fav complete -h` for more information. (e.g. run `fav complete --shell fish --register ~/.config/fish/completions` to register the auto completion script for `fish`)
+- I'll also upload some other auto completion scripts for `bash` and `powershell` and so on.
