2  ------------------------  ------------------------
4  Release 7.0 23-Nov-06  
5    Release 7.2 30-Apr-07
6    ---------------------
8    WARNING: saved patterns that were compiled by earlier versions of PCRE must be
9    recompiled for use with 7.2 (necessitated by the addition of \K).
11    Correction to the notes for 7.1: the note about shared libraries for Windows is
12    wrong. Previously, three libraries were built, but each could function
13    independently. For example, the pcreposix library also included all the
14    functions from the basic pcre library. The change is that the three libraries
15    are no longer independent. They are like the Unix libraries. To use the
16    pcreposix functions, for example, you need to link with both the pcreposix and
17    the basic pcre library.
19    Some more features from Perl 5.10 have been added:
21      (?-n) and (?+n) relative references for recursion and subroutines.
23      (Not sure if this one is actually in Perl 5.10)
24      (?(-n) and (?(+n) relative references as conditions.
26      \K to reset the start of the matched string; for example, (foo)\Kbar
27      matches bar preceded by foo, but only sets bar as the matched string
30    Release 7.1 24-Apr-07
31    ---------------------
33    There is only one new feature in this release: a linebreak setting of
34    PCRE_NEWLINE_ANYCRLF. It is a cut-down version of PCRE_NEWLINE_ANY, which
35    recognizes only CRLF, CR, and LF as linebreaks.
37    A few bugs are fixed (see ChangeLog for details), but the major change is a
38    complete re-implementation of the build system. This now has full Autotools
39    support and so is now "standard" in some sense. It should help with compiling
40    PCRE in a wide variety of environments.
42    NOTE: when building shared libraries for Windows, three dlls are now built,
43    called libpcre, libpcreposix, and libpcrecpp. Previously, everything was
44    included in a single dll.
46    Another important change is that the dftables auxiliary program is no longer
47    compiled and run at "make" time by default. Instead, a default set of character
48    tables (assuming ASCII coding) is used. If you want to use dftables to generate
49    the character tables as previously, add --enable-rebuild-chartables to the
50    "configure" command. You must do this if you are compiling PCRE to run on a
51    system that uses EBCDIC code.
53    There is a discussion about character tables in the README file. The default is
54    not to use dftables so that that there is no problem when cross-compiling.
