8  There are no new features in this release. A few bugs are fixed (see ChangeLog  Correction to the notes for 7.1: the note about shared libraries for Windows is
9  for details), but the major change is a complete re-implementation of the build  wrong. Previously, three libraries were built, but each could function
10  system. This now has full Autotools support and so is now "standard" in some  independently. For example, the pcreposix library also included all the
11  sense. It should help with compiling PCRE in a wide variety of environments.  functions from the basic pcre library. The change is that the three libraries
12    are no longer independent. They are like the Unix libraries. To use the
13    pcreposix functions, for example, you need to link with both the pcreposix and
14    the basic pcre library.
15    
16    Some more features from Perl 5.10 have been added:
17    
18      (?-n) and (?+n) relative references for recursion and subroutines.
19    
20      (Not sure if this one is actually in Perl 5.10)
21      (?(-n) and (?(+n) relative references as conditions.

24    Release 7.1 24-Apr-07
25    ---------------------
26    
27    There is only one new feature in this release: a linebreak setting of
28    PCRE_NEWLINE_ANYCRLF. It is a cut-down version of PCRE_NEWLINE_ANY, which
29    recognizes only CRLF, CR, and LF as linebreaks.
30    
31    A few bugs are fixed (see ChangeLog for details), but the major change is a
32    complete re-implementation of the build system. This now has full Autotools
33    support and so is now "standard" in some sense. It should help with compiling
34    PCRE in a wide variety of environments.
35    
36    NOTE: when building shared libraries for Windows, three dlls are now built,
37    called libpcre, libpcreposix, and libpcrecpp. Previously, everything was
38    included in a single dll.
39    
40    Another important change is that the dftables auxiliary program is no longer
41    compiled and run at "make" time by default. Instead, a default set of character
42    tables (assuming ASCII coding) is used. If you want to use dftables to generate
43    the character tables as previously, add --enable-rebuild-chartables to the
44    "configure" command. You must do this if you are compiling PCRE to run on a
45    system that uses EBCDIC code.
46    
47    There is a discussion about character tables in the README file. The default is
48    not to use dftables so that that there is no problem when cross-compiling.
