  • Add Options.Applicative.NonEmpty.some1 function, which
    parses options the same as some1 from base, but doesn't
    cause duplicates in the usage texts.

  • Further improve help text generation in the presence
    of optional values when nesting is involved, and many and
    some when displayed with a suffix.

  • Add "global" options to the usage texts for subcommands.
    When using subcommands, a "global options" section can
    now appear below the options and commands sections.

    Global options are off by default, to enable them, use
    the helpShowGlobals modifier.

    The noGlobal builder will suppress a single option being
    displayed in the global options list.

    Fixes issues:

    • # 175 - List detailed subparser documentation with --help
    • # 294 - Displaying global options when listing options for a command.
    • # 359 - Subcommand help text lacks required parent command arguments

  • Allow the --help option to take the name of a command.
    Usage without any arguments is the same, but now, when an
    argument is given, if it is the name of a currently
    reachable command, the help text for that command will
    be show.

    Fixes issues:

    • # 379 - cmd --help subcmd is not the same as cmd subcmd --help

  • Updated dependency bounds.

  • Add builder for the all positional parser policy.

  • Remove deprecated functions

    • nullOption
    • execParserMaybe
    • customExecParserMaybe
