# Breaking: #75942 - BigDocumentTemplate class removed

See [forge#75942](https://forge.typo3.org/issues/75942)

## Description

The following class has been removed:

`TYPO3CMSBackendTemplateBigDocumentTemplate`

## Impact

Extensions that still use the removed class for their backend module won't work.

## Affected installations

A TYPO3 instance is affected if a 3rd party extension uses the removed class.

## Migration

Use `TYPO3CMSBackendTemplateDocumentTemplate` instead.
