Angular 11 and Angular 12 upgrade

[Yannick]

Hi,

According to your documentation "The latest versions of the packages are compatible with the Active and LTS versions of Angular. "

But when upgrading from Angular 10 to 11 and Angular 11 to 12, I get the following errors:

$ ng update @angular/core@12 @angular/cli@12
Installing a temporary version to perform the update.

Peer dependency warnings when installing dependencies means that those dependencies might not work correctly together.
You can use the '--force' option to ignore incompatible peer dependencies and instead address these warnings later.

Hi Yannick,

Indeed, all latest Kendo UI for Angular versions are compatible with Angular 11 and 12. The demonstrated error suggests that you are using an outdated version of the @progress/kendo-angular-layout package. In order to make sure that you are using the latest official versions of all Kendo UI for Angular packages you can use the commands demonstrated in the following article:

https://www.telerik.com/kendo-angular-ui/components/installation/up-to-date/#toc-updating-to-latest-versions

Once the the Kendo package versions are updated in the package.json file please make sure that they are reinstalled.

I hope this helps. Please let me know in case any further information is required for this case.

Regards,
Svet
