What happened to Myth/Auth support in newer versions of CI Wiz?

Myth/Auth support was available in CI Wiz 2.x. In CI Wiz 3.x, Shield is the default and Myth/Auth is no longer actively maintained or tested against. For existing apps built with CI Wiz + Myth/Auth: Myth/Auth itself is in maintenance mode upstream and the library author has recommended migrating to Shield. You can keep using Myth/Auth in your existing app as long as it works, but for new projects use Shield. A migration path would involve swapping the auth library and adapting your user model, login/register controllers, and filters — CI Wiz does not automate that migration for existing codebases.
