Breaking Changes in 15.0.0

Updated on Aug 11, 2026

Chart

The obsolete template syntax with literals and inline expressions is not supported. Instead, set the Template parameter to the name of a JavaScript function that returns the required content. This change is also related to CSP compliance.

Using Chart templates up to version 14.1.0 and after version 15.0.0
