4    Release 7.0 23-Nov-06
5    ---------------------
6    
7    This release has a new major number because there have been some internal
8    upheavals to facilitate the addition of new optimizations and other facilities,
9    and to make subsequent maintenance and extension easier. Compilation is likely
10    to be a bit slower, but there should be no major effect on runtime performance.
11    Previously compiled patterns are NOT upwards compatible with this release. If
12    you have saved compiled patterns from a previous release, you will have to
13    re-compile them. Important changes that are visible to users are:
14    
15    1. The Unicode property tables have been updated to Unicode 5.0.0, which adds
16       some more scripts.
17    
18    2. The option PCRE_NEWLINE_ANY causes PCRE to recognize any Unicode newline
19       sequence as a newline.
20    
21    3. The \R escape matches a single Unicode newline sequence as a single unit.
22    
23    4. New features that will appear in Perl 5.10 are now in PCRE. These include
24       alternative Perl syntax for named parentheses, and Perl syntax for
25       recursion.
26    
27    5. The C++ wrapper interface has been extended by the addition of a
28       QuoteMeta function and the ability to allow copy construction and
29       assignment.
30    
31    For a complete list of changes, see the ChangeLog file.

34    Release 6.7 04-Jul-06
35    ---------------------
36    
37    The main additions to this release are the ability to use the same name for
38    multiple sets of parentheses, and support for CRLF line endings in both the
39    library and pcregrep (and in pcretest for testing).
40    
41    Thanks to Ian Taylor, the stack usage for many kinds of pattern has been
42    significantly reduced for certain subject strings.
