Release 7.8 25-Aug-08 |
| 6 |
|
--------------------- |
| 7 |
|
|
| 8 |
|
More bug fixes, plus a performance improvement in Unicode character property |
| 9 |
|
lookup. |
| 10 |
|

|
|

|
Release 7.7 07-May-08 |
| 13 |
|
--------------------- |
| 14 |
|
|
| 15 |
|
This is once again mainly a bug-fix release, but there are a couple of new |
| 16 |
|
features. |
| 17 |
|
|
| 18 |
|
|
| 19 |
|
Release 7.6 28-Jan-08 |
| 20 |
|
--------------------- |
| 21 |
|
|
| 22 |
|
The main reason for having this release so soon after 7.5 is because it fixes a |
| 23 |
|
potential buffer overflow problem in pcre_compile() when run in UTF-8 mode. In |
| 24 |
|
addition, the CMake configuration files have been brought up to date. |
| 25 |
|
|
| 26 |
|
|
| 27 |
|
Release 7.5 10-Jan-08 |
| 28 |
|
--------------------- |
| 29 |
|
|
| 30 |
|
This is mainly a bug-fix release. However the ability to link pcregrep with |
| 31 |
|
libz or libbz2 and the ability to link pcretest with libreadline have been |
| 32 |
|
added. Also the --line-offsets and --file-offsets options were added to |
| 33 |
|
pcregrep. |
| 34 |
|
|
| 35 |
|
|
| 36 |
|
Release 7.4 21-Sep-07 |
| 37 |
|
--------------------- |
| 38 |
|
|
| 39 |
|
The only change of specification is the addition of options to control whether |
| 40 |
|
\R matches any Unicode line ending (the default) or just CR, LF, and CRLF. |
| 41 |
|
Otherwise, the changes are bug fixes and a refactoring to reduce the number of |
| 42 |
|
relocations needed in a shared library. There have also been some documentation |
| 43 |
|
updates, in particular, some more information about using CMake to build PCRE |
| 44 |
|
has been added to the NON-UNIX-USE file. |
| 45 |
|
|
| 46 |
|
|
| 47 |
|
Release 7.3 28-Aug-07 |
| 48 |
|
--------------------- |
| 49 |
|
|
| 50 |
|
Most changes are bug fixes. Some that are not: |
| 51 |
|
|
| 52 |
|
1. There is some support for Perl 5.10's experimental "backtracking control |
| 53 |
|
verbs" such as (*PRUNE). |
| 54 |
|
|
| 55 |
|
2. UTF-8 checking is now as per RFC 3629 instead of RFC 2279; this is more |
| 56 |
|
restrictive in the strings it accepts. |
| 57 |
|
|
| 58 |
|
3. Checking for potential integer overflow has been made more dynamic, and as a |
| 59 |
|
consequence there is no longer a hard limit on the size of a subpattern that |
| 60 |
|
has a limited repeat count. |
| 61 |
|
|
| 62 |
|
4. When CRLF is a valid line-ending sequence, pcre_exec() and pcre_dfa_exec() |
| 63 |
|
no longer advance by two characters instead of one when an unanchored match |
| 64 |
|
fails at CRLF if there are explicit CR or LF matches within the pattern. |
| 65 |
|
This gets rid of some anomalous effects that previously occurred. |
| 66 |
|
|
| 67 |
|
5. Some PCRE-specific settings for varying the newline options at the start of |
| 68 |
|
a pattern have been added. |
| 69 |

|
Release 7.2 19-Jun-07 |
| 72 |
|
--------------------- |
| 73 |
|
|
| 74 |
|
WARNING: saved patterns that were compiled by earlier versions of PCRE must be |
| 75 |
|
recompiled for use with 7.2 (necessitated by the addition of \K, \h, \H, \v, |
| 76 |
|
and \V). |
| 77 |
|
|
| 78 |
|
Correction to the notes for 7.1: the note about shared libraries for Windows is |
| 79 |
|
wrong. Previously, three libraries were built, but each could function |
| 80 |
|
independently. For example, the pcreposix library also included all the |
| 81 |
|
functions from the basic pcre library. The change is that the three libraries |
| 82 |
|
are no longer independent. They are like the Unix libraries. To use the |
| 83 |
|
pcreposix functions, for example, you need to link with both the pcreposix and |
| 84 |
|
the basic pcre library. |
| 85 |
|
|
| 86 |
|
Some more features from Perl 5.10 have been added: |
| 87 |
|
|
| 88 |
|
(?-n) and (?+n) relative references for recursion and subroutines. |
| 89 |
|
|
| 90 |
|
(?(-n) and (?(+n) relative references as conditions. |
| 91 |
|
|
| 92 |
|
\k{name} and \g{name} are synonyms for \k<name>. |
| 93 |
|
|
| 94 |
|
\K to reset the start of the matched string; for example, (foo)\Kbar |
| 95 |
|
matches bar preceded by foo, but only sets bar as the matched string. |
| 96 |
|
|
| 97 |
|
(?| introduces a group where the capturing parentheses in each alternative |
| 98 |
|
start from the same number; for example, (?|(abc)|(xyz)) sets capturing |
| 99 |
|
parentheses number 1 in both cases. |
| 100 |
|
|
| 101 |
|
\h, \H, \v, \V match horizontal and vertical whitespace, respectively. |
