perldelta - what is new for perl v5.19.7

=head2 Postfix syntax for maximum array index
The postfix notation C<< ->$#* >> has been added, to match the similar

-XXX Descriptions of platform agnostic bugs we know we can't fix go here. Any
-tests that had to be C<TODO>ed for the release would be noted here. Unfixed
-platform specific bugs also go here.
+Fix HP-UX $! failure. HP-UX strerror() returns an empty string for an
+unknown error code. This caused an assertion to fail under DEBUGGING
+builds. This patch removes the assertion and changes the return into
+a non-empty string indicating the errno is for an unknown error.
-[ List each fix as a =item entry ]
+=item *
-=over 4
+Fix unexpected tainting via regexp using locale. Previously, under certain
+conditions, the use of character classes could cause tainting when it
+shouldn't. Some character classes are locale-dependent, but before this
+patch, sometimes tainting was happening even for character classes that
+don't depend on the locale. [perl #120675]
=item *
-XXX
+Under certain conditions, Perl would throw an error if in an lookbehind
+assertion in a regexp, the assertion referred to a named subpattern,
+complaining the lookbehind was variable when it wasn't. This has been
+fixed. [perl #120600], [perl #120618]. The current fix may be improved
+on in the future.
