+- Update to 2.24
+  * grep -z would match strings it should not.  To trigger the bug, 
+    you'd have to use a regular expression including an anchor 
+    (^ or $) and a feature like a range or a backreference, causing 
+    grep to forego its DFA matcher and resort to using re_search.
+    With a multibyte locale, that matcher could mistakenly match a 
+    string containing a newline. For example, this command: 
+    printf 'a\nb\0' | LC_ALL=en_US.utf-8 grep -z '^[a-b]*b'
+    would mistakenly match and print all four input bytes.  After 
+    the fix, there is no match, as expected.
+    [bug introduced in grep-2.7]
+  * grep -Pz now diagnoses attempts to use patterns containing ^ 
+    and $, instead of mishandling these patterns.  This problem 
+    seems to be inherent to the PCRE API; removing this limitation 
+    is on PCRE's maint/README wish list.  Patterns can continue to 
+    match literal ^ and $ by escaping them with \ (now needed even 
+    inside [...]). [bug introduced in grep-2.5]
