Subject: [PATCH] =?UTF-8?q?=E2=9C=A8=20Use=20Context=20API=20to=20check=20?=
 =?UTF-8?q?for=20logged=20in=20backend=20user?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The `isBackendUserLoggedIn()` function of the TSFE array is deprecated
starting with TYPO3 v12 and since the Context API also provides the
necssary aspect and functionality in v11 there is no harm in migrating
now.
