Build 5.20191.615 has released. It includes Angular 8 support, some nice new enhancements and several bug fixes. It also includes a fix for AOT compiling in Angular.
To get our Angular components use:
npm install @grapecity/wijmo.angular2.all
One thing we ran into is needing to update all of our ViewChild() decorators in many of our sample applications. You will likely run into this if you are upgrading to Angular 8 from an earlier verison. Use this upgrade guide for help.
