This introduce a backward incompatible change for filesystem path matching
in the Event Manager, now patterns like "*.txt" will no longer match any
file with the "txt" suffix, you need to change them to "/**/*.txt".
Also change pre-delete behaviour, now if an error is returned the client
will get a permission denied error. This is the same as the other pre-*
action. Previously it was not possible to deny deletion of a file.
