This release fixes compiling expressions with global extended modifier that is disabled by local no-extended option at the start of the expression just after a whitespace, a possible crash in pcre_copy_named_substring() if a named substring has number greater than the space in the ovector, a buffer overflow when compiling an expression with named groups with a group that resets capture numbers, a crash in pcre_get_substring_list() if the use of \K caused the start of the match to be earlier than the end.
