# Breaking: #96879 - Hook "get_cache_timeout" removed

See [forge#96879](https://forge.typo3.org/issues/96879)

## Description

The hook `$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['get_cache_timeout']`
used in TYPO3 Frontend for changing the cache timeout of a page stored in the
TYPO3 "pages" cache has been removed.

## Impact

If an extension has registered a hook in `ext_localconf.php` it will not
be executed anymore in TYPO3 v12 or later.

## Affected Installations

TYPO3 installations using this hook in custom extensions.

## Migration

Use the newly introduced PSR-14 event [ModifyCacheLifetimeForPageEvent](https://docs.typo3.org/permalink/changelog:feature-96879-1663513042)
and register a custom event listener.
