 * [#10][#732][#1047] API: Support abbreviated options and commands. Thanks to [NewbieOrange](https://github.com/NewbieOrange) for the pull request.
 * [#1051][#1056] Enhancement: `GenerateCompletion` command no longer needs to be a direct subcommand of the root command. Thanks to [Philippe Charles](https://github.com/charphi) for the pull request.
-* [1065] Bugfix: With a `List<>` option in `@ArgGroup`, group incorrectly appears twice in the synopsis. Thanks to [kap4lin](https://github.com/kap4lin) for raising this.
+* [#1068] Enhancement: Make `ParserSpec::toString` output settings in alphabetic order.
+* [#1069] Enhancement: Debug output should show `optionsCaseInsensitive` and `subcommandsCaseInsensitive` settings.
