@ -15,6 +15,8 @@ Changes to the help system (most normal users will not notice this):
* Removed `help_*` functions.
* Protected function `_has_help_positional` removed.
* `format_help` can now be chained.
* Added getters for the missing parts of options (help no longer uses any private parts).
* Help flags now use new `short_circuit` property to simplify parsing. [#121]
New for Config file reading and writing [#121]:

Other changes:
* Fixing `parse(args)`'s `args` setting and ordering after parse. [#141]
* Cleaner tests without `app.reset()` (and `reset` is now `clear`). [#141]
* Replaced `set_custom_option` with `type_name` and `type_size` instead of `set_custom_option`. Methods return `this`. [#136]
* Dropped `set_` on Option's `type_name`, `default_str`, and `default_val`. [#136]
* Removed `set_` from App's `failure_message`, `footer`, `callback`, and `name`. [#136]
@ -46,18 +47,20 @@ Other changes:
* Added `->each()` to make adding custom callbacks easier. [#126]
* Added filter argument to `get_subcommands`, `get_options`; use empty filter `{}` to avoid filtering.
* Added `get_groups()` to get groups.
* Added getters for the missing parts of options (help no longer uses any private parts).
* Better support for manual options with `get_option`, `set_results`, and `empty`. [#119]
* `lname` and `sname` have getters, added `const get_parent`. [#120]
* Using `add_set` will now capture L-values for sets, allowing further modification. [#113]
* Internally, `type_name` is now a lambda function; for sets, this reads the set live. [#116]
* Dropped duplicate way to run `get_type_name` (`get_typeval`).
* Testing (only) now uses submodules. [#111]
* Removed `requires` in favor of `needs` (deprecated in last version). [#112]
* Const added to argv. [#126]
Backend and testing changes:
* Internally, `type_name` is now a lambda function; for sets, this reads the set live. [#116]
* Cleaner tests without `app.reset()` (and `reset` is now `clear`). [#141]
* Better CMake policy handling. [#110]
* Includes are properly sorted. [#120]
* Help flags now use new `short_circuit` property to simplify parsing. [#121]
* Const added to argv. [#126]
* Testing (only) now uses submodules. [#111]
