0.12.1

• Replace ArgParser.getUsage() with ArgParser.usage, a getter. ArgParser.getUsage() is now deprecated, to be removed in args version 1.0.0.

0.12.0+2

• Widen the version constraint on the collection package.

0.12.0+1

• Remove the documentation link from the pubspec so this is linked to pub.dartlang.org by default.

0.12.0

• Removed public constructors for ArgResults and Option.

• ArgResults.wasParsed() can be used to determine if an option was actually parsed or the default value is being returned.

• Replaced isFlag and allowMultiple fields in the Option class with a three-value OptionType enum.

• Options may define valueHelp which will then be shown in the usage.

0.11.0

• Move handling trailing options from ArgParser.parse() into ArgParser itself. This lets subcommands have different behavior for how they handle trailing options.

0.10.0+2

• Usage ignores hidden options when determining column widths.
