 1. Callouts with string arguments have been added.
@@ -167,6 +167,14 @@ now compatible with the specification in Perl's perlebcdic page.
 43. Single character repetition in JIT has been improved. 20-30% speedup
 was achieved on certain patterns.
 
+44. The EBCDIC character 0x41 is a non-breaking space, equivalent to 0xa0 in
+ASCII/Unicode. This has now been added to the list of characters that are
+recognized as white space in EBCDIC.
+    
+45. When PCRE2 was compiled without Unicode support, the use of \p and \P gave
+an error (correctly) when used outside a class, but did not give an error
+within a class.
