Our primary product, XLTS for AngularJS, does not officially support Ionic Framework v1. AngularJS 1.6.x introduced breaking changes that aren't compatible with Ionic v1.
For companies who specifically need a supported version of AngularJS, we have a new XLTS for AngularJS 1.5.x product that meets their needs. This includes the latest code from the AngularJS
1.5.x branch plus security fixes that our team has back-ported from more recent AngularJS releases.
