v0.28.1

Added

• Added true-color themes tc24d-blue and tc24l-blue for dark and light terminals by @pamburus in #217
  These themes can be useful with most pager since it converts regular palette colors to 24-bit true colors using its own palette, which may differ from the settings of the terminal application used. Also, it currently doesn't support faint attribute that is used in universal theme and its variants.
• Added support for theme preview with fzf by @pamburus in #224
  Example usage:

  hl --list-themes | fzf --preview-window="top,80%" --preview="head -n 100 example.log | hl -c --theme {}"

Changed

• Updated performance section in README.md by @pamburus in #218
• Flag -c can now be overridden by --color option by @pamburus in #220 and #223
• All options are now logically grouped in the help output by @pamburus in #222

Fixed

• Fixed references to the original file format in the help by @pamburus in #219
• Improved value names in command line options by @pamburus in #221
• Fixed level style in classic and classic-light themes by @pamburus in #225

Maintenance

• Updated dependencies by @pamburus in #216
