# Breaking Changes in 15.0.0

## Chart, Map

The [obsolete template syntax](https://www.telerik.com/blazor-ui/documentation/upgrade/breaking-changes/14-0-0#chart-map) with literals and inline expressions is not supported. Instead, set the [Chart `Template` parameter](https://www.telerik.com/blazor-ui/documentation/components/chart/labels-template-and-format#templates) and [Map `UrlTemplate` parameter](https://www.telerik.com/blazor-ui/documentation/components/map/overview) to the name of a JavaScript function that returns the required content. This change is also related to [CSP compliance](https://www.telerik.com/blazor-ui/documentation/troubleshooting/csp#policy-configuration).
