According to this topic: https://mdbootstrap.com/support/error-after-update-to-angular-6/ was stated that 6.1.1 version of the library won't have legacy dependencies. I've downloaded version 6.1.1 package from profile -> my account -> orders & invoices -> MDB_ANGULAR_PRO_6.1.1.ZIP. Package doesn't have legacy dependencies but fails to compile with the following: ERROR in node_modules/@agm/core/services/google-maps-api-wrapper.d.ts(2,10): error TS2305: Module '"../node_modules/rxjs/Observable"' has no exported member 'Observable'. node_modules/@agm/core/services/managers/circle-manager.d.ts(2,10): error TS2305: Module '"../node_modules/rxjs/Observable"' has no exported member 'Observable'. node_modules/@agm/core/services/managers/data-layer-manager.d.ts(2,10): error TS2305: Module '"../node_modules/rxjs/Observable"' has no exported member 'Observable'. node_modules/@agm/core/services/managers/info-window-manager.d.ts(1,10): error TS2305: Module '"../node_modules/rxjs/Observable"' has no exported member 'Observable'. node_modules/@agm/core/services/managers/kml-layer-manager.d.ts(2,10): error TS2305: Module '"../node_modules/rxjs/Observable"' has no exported member 'Observable'. node_modules/@agm/core/services/managers/marker-manager.d.ts(2,10): error TS2305: Module '"../node_modules/rxjs/Observable"' has no exported member 'Observable'. node_modules/@agm/core/services/managers/polygon-manager.d.ts(2,10): error TS2305: Module '"../node_modules/rxjs/Observable"' has no exported member 'Observable'. node_modules/@agm/core/services/managers/polyline-manager.d.ts(2,10): error TS2305: Module '"../node_modules/rxjs/Observable"' has no exported member 'Observable'. node_modules/rxjs/Observable.d.ts(1,15): error TS2307: Cannot find module 'rxjs-compat/Observable'. Naturally, adding rxjs-compat dependency solves the problem. So the question is when the package won't need this dependency?
