7    1.  A character class containing a very large number of characters with
8        codepoints greater than 255 (in UTF-8 mode, of course) caused a buffer
9        overflow.
10    
11    2.  Patch to cut out the "long long" test in pcrecpp_unittest when
12        HAVE_LONG_LONG is not defined.

111  20. In pcrecpp.cc, the variable 'count' was incremented twice in  20. In pcrecpp.cc, the variable 'count' was incremented twice in
112      RE::GlobalReplace(). As a result, the number of replacements returned was      RE::GlobalReplace(). As a result, the number of replacements returned was
113      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
114        later patch that removed the other one (the right fix) and added unit tests
115        that check the return values (which was not done before).
116    
117    21. Several CMake things:
118    
119        (1) Arranged that, when cmake is used on Unix, the libraries end up with
120            the names libpcre and libpcreposix, not just pcre and pcreposix.
121    
122        (2) The above change means that pcretest and pcregrep are now correctly
123            linked with the newly-built libraries, not previously installed ones.
124    
125        (3) Added PCRE_SUPPORT_LIBREADLINE, PCRE_SUPPORT_LIBZ, PCRE_SUPPORT_LIBBZ2.
126    
127    22. In UTF-8 mode, with newline set to "any", a pattern such as .*a.*=.b.*
128        crashed when matching a string such as a\x{2029}b (note that \x{2029} is a
129        UTF-8 newline character). The key issue is that the pattern starts .*;
130        this means that the match must be either at the beginning, or after a
131        newline. The bug was in the code for advancing after a failed match and
132        checking that the new position followed a newline. It was not taking
133        account of UTF-8 characters correctly.
134    
135    23. PCRE was behaving differently from Perl in the way it recognized POSIX
136        character classes. PCRE was not treating the sequence [:...:] as a
137        character class unless the ... were all letters. Perl, however, seems to
138        allow any characters between [: and :], though of course it rejects as
139        unknown any "names" that contain non-letters, because all the known class
140        names consist only of letters. Thus, Perl gives an error for [[:1234:]],
141        for example, whereas PCRE did not - it did not recognize a POSIX character
142        class. This seemed a bit dangerous, so the code has been changed to be
143        closer to Perl. The behaviour is not identical to Perl, because PCRE will
144        diagnose an unknown class for, for example, [[:l\ower:]] where Perl will
145        treat it as [[:lower:]]. However, PCRE does now give "unknown" errors where
146        Perl does, and where it didn't before.
147    
148    24. Rewrite so as to remove the single use of %n from pcregrep because in some
149        Windows environments %n is disabled by default.
