Release 7.0 23-Nov-06 |
| 5 |
|
--------------------- |

|
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. |
