We are in the process of migrating our application from Angular v20 to v21. While upgrading Angular CLI and Core to v21 worked without issues, we encountered compatibility problems when updating Angular CDK and Material to v21 alongside Ignite UI.
Specifically:
- @infragistics/igniteui-angular has a v21 release, but
- igniteui-angular-core and igniteui-angular-excel appear to remain at v20 versions.
- This mismatch is causing dependency conflicts and runtime errors when we attempt to align all packages with Angular 21

Could you please confirm:
- The planned release timeline for Ignite UI Core v21 and Ignite UI Excel v21.
- Whether there are recommended workarounds until these packages are updated (e.g., holding CDK/Material at v20).
- Any migration notes or guidance for teams moving to Angular 21 with Ignite UI.
We rely heavily on Ignite UI Core and Excel features, so clarity on the upgrade path will help us plan our migration effectively.
