Breaking: #92352 - New default position for redirect middleware¶
TYPO3 10 introduced the feature toggle

typo3/cms-frontend/base-redirect-resolver. While this might cause problems in some scenarios it is by
far the better default.
Therefore the feature switch has been removed now and the above described order is the new default.
By putting the
typo3/cms-frontend/base-redirect-resolver last, redirects are always resolved even if no

If needed the order of the middlewares can be switched back manually as described in the documentation.
