7    Important changes in this release:
8    
9    1. A number of new features have been added to pcregrep.
10    
11    2. The Unicode property tables have been updated to Unicode 4.1.0, and the
12       supported properties have been extended with script names such as "Arabic",
13       and the derived properties "Any" and "L&". This has necessitated a change to
14       the interal format of compiled patterns. Any saved compiled patterns that
15       use \p or \P must be recompiled.
16    
17    3. The specification of recursion in patterns has been changed so that all
18       recursive subpatterns are automatically treated as atomic groups. Thus, for
19       example, (?R) is treated as if it were (?>(?R)). This is necessary because
20       otherwise there are situations where recursion does not work.
21    
22    See the ChangeLog for a complete list of changes, which include a number of bug
23    fixes and tidies.
