  ChangeLog for PCRE
  ------------------
- Version 7.5 23-Dec-07
+ Version 7.6 28-Jan-08
+ ---------------------
+.  A character class containing a very large number of characters with
+     codepoints greater than 255 (in UTF-8 mode, of course) caused a buffer
+     overflow.
+.  Patch to cut out the "long long" test in pcrecpp_unittest when
+     HAVE_LONG_LONG is not defined.
+.  Applied Christian Ehrlicher's patch to update the CMake build files to
+     bring them up to date and include new features. This patch includes:
+     - Fixed PH's badly added libz and libbz2 support.
+     - Fixed a problem with static linking.
+     - Added pcredemo. [But later removed - see 7 below.]
+     - Fixed dftables problem and added an option.
+     - Added a number of HAVE_XXX tests, including HAVE_WINDOWS_H and
+         HAVE_LONG_LONG.
+     - Added readline support for pcretest.
+     - Added an listing of the option settings after cmake has run.
+.  A user submitted a patch to Makefile that makes it easy to create
+     "pcre.dll" under mingw when using Configure/Make. I added stuff to
+     Makefile.am that cause it to include this special target, without
+     affecting anything else. Note that the same mingw target plus all
+     the other distribution libraries and programs are now supported
+     when configuring with CMake (see 6 below) instead of with
+     Configure/Make.
+.  Applied Craig's patch that moves no_arg into the RE class in the C++ code.
+     This is an attempt to solve the reported problem "pcrecpp::no_arg is not
+     exported in the Windows port". It has not yet been confirmed that the patch
+     solves the problem, but it does no harm.
+.  Applied Sheri's patch to CMakeLists.txt to add NON_STANDARD_LIB_PREFIX and
+     NON_STANDARD_LIB_SUFFIX for dll names built with mingw when configured
+     with CMake, and also correct the comment about stack recursion.
+.  Remove the automatic building of pcredemo from the ./configure system and
+     from CMakeLists.txt. The whole idea of pcredemo.c is that it is an example
+     of a program that users should build themselves after PCRE is installed, so
+     building it automatically is not really right. What is more, it gave
+     trouble in some build environments.
+.  Further tidies to CMakeLists.txt from Sheri and Christian.
+ Version 7.5 10-Jan-08
  ---------------------
 .  Applied a patch from Craig: "This patch makes it possible to 'ignore'

 . In pcrecpp.cc, the variable 'count' was incremented twice in
      RE::GlobalReplace(). As a result, the number of replacements returned was
-     double what it should be. I have removed one of the increments.
+     double what it should be. I removed one of the increments, but Craig sent a
+     later patch that removed the other one (the right fix) and added unit tests
+     that check the return values (which was not done before).
 . Several CMake things:
      (1) Arranged that, when cmake is used on Unix, the libraries end up with
-         the names libpcre and libpcreposix.
+         the names libpcre and libpcreposix, not just pcre and pcreposix.
-     (2) Arranged for pcretest and pcregrep to link with the newly-built
+     (2) The above change means that pcretest and pcregrep are now correctly
-         libraries, not previously installed ones.
+         linked with the newly-built libraries, not previously installed ones.
      (3) Added PCRE_SUPPORT_LIBREADLINE, PCRE_SUPPORT_LIBZ, PCRE_SUPPORT_LIBBZ2.
+. In UTF-8 mode, with newline set to "any", a pattern such as .*a.*=.b.*
+     crashed when matching a string such as a\x{2029}b (note that \x{2029} is a
+     UTF-8 newline character). The key issue is that the pattern starts .*;
+     this means that the match must be either at the beginning, or after a
+     newline. The bug was in the code for advancing after a failed match and
+     checking that the new position followed a newline. It was not taking
+     account of UTF-8 characters correctly.
+. PCRE was behaving differently from Perl in the way it recognized POSIX
+     character classes. PCRE was not treating the sequence [:...:] as a
+     character class unless the ... were all letters. Perl, however, seems to
+     allow any characters between [: and :], though of course it rejects as
+     unknown any "names" that contain non-letters, because all the known class
+     names consist only of letters. Thus, Perl gives an error for [[:1234:]],
+     for example, whereas PCRE did not - it did not recognize a POSIX character
+     class. This seemed a bit dangerous, so the code has been changed to be
+     closer to Perl. The behaviour is not identical to Perl, because PCRE will
+     diagnose an unknown class for, for example, [[:l\ower:]] where Perl will
+     treat it as [[:lower:]]. However, PCRE does now give "unknown" errors where
+     Perl does, and where it didn't before.
+. Rewrite so as to remove the single use of %n from pcregrep because in some
+     Windows environments %n is disabled by default.
