v2.8.1 (2023-08-25)
Fixed

v2.8.0 (2023-08-25)
Added
 - i{file name}<CR> to create new file, and I{dir name}<CR> to create new
   directory.
 - If zoxide is installed, whenever changing directory inside felix, zoxide add
   will be executed to add the directory or increment its rank in the zoxide
   database.
    - For this, State now has a new field has_zoxide, which is checked at
      startup.

Changed
 - config's color is now optional: By this, all config fields are optional.
    - Remove warning message when you launch felix without the config file.
 - When opening file by default editor is failed, felix displays more accurate
   warning: $EDITOR may not be set, or config file may be invalid..

Removed
 - Remove syntect and syntax highlighting in the preview area.
   This will improve build and start-up times, and resolve the handling of
   wide chars such as CJK.
