-- Some internal refactors:
+- Some internal refactors. These refactors are aimed at making the abstractions more maintainable over time, more consistent, and more adept for advanced used cases.
   - `rich_click.py` is exclusively the global config; all formatting has been moved to `rich_help_rendering.py`.
   - `RichCommand` now makes use of methods in the super class: `format_usage`, `format_help_text`, `format_options`, and `format_epilog`.
   - Global `formatter` object has been removed from the code.
+  - `highlighter` is now constructed by the `RichHelpFormatter` rather than being inside the config object.
 - Added `RichHelpConfiguration.load_from_globals()` classmethod, which pulls all configuration from `rich_click.py`.
 - Fix bug with regex highlighter for options and switches.
 - `RichHelpConfiguration()` is now asserted to be JSON serializable, as an option for porting configurations. That said, serialization is not a fully supported feature of the high-level API, so serialize the config at your own risk.
+  - Related: `highlighter` is now deprecated in `RichHelpConfiguration`; please use `highlighter_patterns` instead.
