 - `NameSpecification` and its elements now conform to `ExpressibleByStringLiteral`, allowing simplified option and flag name declarations. For example, `[.customLong("hex-output"), .customShort("x")]` can now be written as `"--hex-output -x"`. ([#745])
 - New `@Option` initializers accept a `defaultAsFlag:` parameter, creating options that work both as a bare flag (`--format`) and as an option with a value (`--format json`). ([#830])
