# Breaking: #85080 - Method "isEnabled()" added to RenderableInterface and FinisherInterface

See [forge#85080](https://forge.typo3.org/issues/85080)

## Description

A new method `isEnabled()` has been added to the `RenderableInterface` as well as the `FinisherInterface`.

## Impact

Third party code implementing these interfaces and not extending `AbstractRenderable` or `AbstractFinisher` will
cause a fatal error if used in a form.

## Affected Installations

Instances with third party code implementing these interfaces and not extending `AbstractRenderable` or `AbstractFinisher`.

## Migration

Third party code implementing these interfaces must be updated to implement the `isEnabled()` method, preferably
by extending `AbstractRenderable` (or one of its subclasses) or `AbstractFinisher`.
