Well, perl5280delta mentions that "delete" can be used on key/value hash slices, and also mentions new syntax for some regular expression stuff. perl5260delta also mentions some syntax changes to regular expressions and some modifications to how here-documents work. perl5240delta mentions some new formatting support for printf and sprintf, and again, more regular expression support.
