- subcommands with an executable handler and only a short help flag are now handled correctly by the parent's help command ([#1930])

###### Added

- `registeredArguments` property on `Command` with the array of defined `Argument` (like `Command.options` for `Option`) ([#2010])
- TypeScript declarations for Option properties: `envVar`, `presetArg` ([#2019])
- TypeScript declarations for Argument properties: `argChoices`, `defaultValue`, `defaultValueDescription` ([#2019])
- example file which shows how to configure help to display any custom usage in the list of subcommands ([#1896])

###### Changed

- (developer) refactor TypeScript configs for multiple use-cases, and enable checks in JavaScript files in supporting editors ([#1969])
