Breaking: #62339 - Move EXT:perm into EXT:beuser and remove EXT:perm¶
See Issue #62339
The extension EXT:perm is removed from core, the perms module is moved into EXT:beuser. The BE module moved from "Web Access" to "System Access"
Extensions that use EXT:perm or maybe depends on it will cause problems
A TYPO3 instance is affected if a 3rd party extension uses parts the removed extension.
The logic is moved into EXT:beuser. No special migration is necessary.
