As of 0.6.3, TextlessActionWidget is unused and deprecated, marked for removal by 0.7.0
Possibly more, I didn't take great notes

new validation ValidatedChoiceList. Similar to ValidatedChoice, but the list version allows for enabling/disabling of none to all of the possible options while the Choice is one and always one of the choices from the options.
- New toChoiceSet helper method in ValidatedList, ValidatedSet, and ValidatedChoice for creation of choice lists from the backing validation.
Added testVersion method to PlatformApi for platform-agnostic testing of MC or mod version
CustomButtonWidget now accepts an activeSupplier to dynamically update active state, and a messageSupplier to dynamically update the button label. See the builder for details.

@Validated[Number].Restrict annotations now accept an optional ValidatedNumber.WidgetType with the new third param type
Reimplemented all instances of ActiveButtonWidget as built or extended-from CustomButtonWidget, and ActiveButtonWidget is now deprecated.
Reimplemented all instances of TextlessActionWidget as built CustomButtonWidget, and TextlessActionWidget is now deprecated.

Fixed suggestion windows not being properly linked up in the config screen.
Several popups, widgets, and so on have better layout and positioning; fixed several weird overlap and underlap issues among other things.
Top and bottom of scrollable lists now position better.
Fixed searching leading to entries "hiding" above the top of the viewport, needing you to scroll up to find them despite not having a scroll bar potentially
Group collapsing now properly positions the bottom of the setting list at the bottom of the list viewport when applicable
