# Deprecation: #86486 - TypoScriptFrontendController->processOutput()

See [forge#86486](https://forge.typo3.org/issues/86486)

## Description

The method `TypoScriptFrontendController->processOutput()` has been
marked as deprecated.

## Impact

Calling this method will trigger a PHP `E_USER_DEPRECATED` error.

## Affected Installations

TYPO3 installations with extensions that use the method.

## Migration

Use `TypoScriptFrontendController->applyHttpHeadersToResponse()` and
`TypoScriptFrontendController->processContentForOutput()` instead, if necessary.
