11  sense. It should help with compiling PCRE in a wide variety of environments.  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:
20    
21      (?-n) and (?+n) relative references for recursion and subroutines.

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.
