Version: 0.8.1
Date: 2021-08-09
  Changes:
    - The dictionary module no longer provides an event to hook, instead returning the finished dictionaries directly from `process_translation`
      - This is to allow a single-source-of-truth for the language's dictionaries, which was the original intention, but returning them in an event broke that intention

    - `misc.delineate_number()` now supports decimal numbers
  Changes:
    - `area.load` will now automatically convert from a shorthanded area to a proper area if needed
    - Deprecated the old `gui` module and replaced it with the contents of `gui-beta`
      - Mods can still require `gui-beta`, but it will simply redirect to `gui` instead
      - Mods that depended on the old GUI module will need to update to the new one or download a copy of it to their mod - it is no longer supported whatsoever
    - Deprecated the `translation` module, replaced by the new `dictionary` module
      - The `translation` module still exists and can be used, but is no longer documented and its use is recommended against
  Bugfixes:

    - Added a third return value to the callback of `table.for_n_of`, which is a flag requesting an immediate iteration abort
    - Added `flib_tool_button_light_green` button style
  Changes:
    - `table.for_n_of` now checks against the first (key) return of `next()` rather than the second (value) return
      - This changes how custom `next()` functions will behave, and brings it into consistency with the rest of Lua

Version: 0.4.0
