 ChangeLog for PCRE  ChangeLog for PCRE
 ------------------  ------------------
   
   Version 8.30 04-February-2012
   -----------------------------
   
   1.  Renamed "isnumber" as "is_a_number" because in some Mac environments this
       name is defined in ctype.h.
   
   2.  Fixed a bug in fixed-length calculation for lookbehinds that would show up
       only in quite long subpatterns.
   
   3.  Removed the function pcre_info(), which has been obsolete and deprecated
       since it was replaced by pcre_fullinfo() in February 2000.
   
   4.  For a non-anchored pattern, if (*SKIP) was given with a name that did not
       match a (*MARK), and the match failed at the start of the subject, a
       reference to memory before the start of the subject could occur. This bug
       was introduced by fix 17 of release 8.21.
   
   5.  A reference to an unset group with zero minimum repetition was giving
       totally wrong answers (in non-JavaScript-compatibility mode). For example,
       /(another)?(\1?)test/ matched against "hello world test". This bug was
       introduced in release 8.13.
   
   6.  Add support for 16-bit character strings (a large amount of work involving
       many changes and refactorings).
   
   7.  RunGrepTest failed on msys because \r\n was replaced by whitespace when the
       command "pattern=`printf 'xxx\r\njkl'`" was run. The pattern is now taken
       from a file.
   
   8.  Ovector size of 2 is also supported by JIT based pcre_exec (the ovector size
       rounding is not applied in this particular case).
   
   9.  The invalid Unicode surrogate codepoints U+D800 to U+DFFF are now rejected
       if they appear, or are escaped, in patterns.
   
   10. Get rid of a number of -Wunused-but-set-variable warnings.
   
   11. The pattern /(?=(*:x))(q|)/ matches an empty string, and returns the mark
       "x". The similar pattern /(?=(*:x))((*:y)q|)/ did not return a mark at all.
       Oddly, Perl behaves the same way. PCRE has been fixed so that this pattern
       also returns the mark "x". This bug applied to capturing parentheses,
       non-capturing parentheses, and atomic parentheses. It also applied to some
       assertions.
   
   12. Stephen Kelly's patch to CMakeLists.txt allows it to parse the version
       information out of configure.ac instead of relying on pcre.h.generic, which
       is not stored in the repository.
   
   13. Applied Dmitry V. Levin's patch for a more portable method for linking with
       -lreadline.
   
   14. ZH added PCRE_CONFIG_JITTARGET; added its output to pcretest -C.
   
   15. Applied Graycode's patch to put the top-level frame on the stack rather
       than the heap when not using the stack for recursion. This gives a
       performance improvement in many cases when recursion is not deep.
   
   16. Experimental code added to "pcretest -C" to output the stack frame size.
