1  News about PCRE releases  News about PCRE releases
2  ------------------------  ------------------------
3    
4    Release 8.12 15-Jan-2011
5    ------------------------
6    
7    This release fixes some bugs in pcregrep, one of which caused the tests to fail
8    on 64-bit big-endian systems. There are no changes to the code of the library.
9    
10    
11    Release 8.11 10-Dec-2010
12    ------------------------
13    
14    A number of bugs in the library and in pcregrep have been fixed. As always, see
15    ChangeLog for details. The following are the non-bug-fix changes:
16    
17    . Added --match-limit and --recursion-limit to pcregrep.
18    
19    . Added an optional parentheses number to the -o and --only-matching options
20      of pcregrep.
21    
22    . Changed the way PCRE_PARTIAL_HARD affects the matching of $, \z, \Z, \b, and
23      \B.
24    
25    . Added PCRE_ERROR_SHORTUTF8 to make it possible to distinguish between a
26      bad UTF-8 sequence and one that is incomplete when using PCRE_PARTIAL_HARD.
27    
28    . Recognize (*NO_START_OPT) at the start of a pattern to set the PCRE_NO_
29      START_OPTIMIZE option, which is now allowed at compile time
30    
31    
32    Release 8.10 25-Jun-2010
33    ------------------------
34    
35    There are two major additions: support for (*MARK) and friends, and the option
36    PCRE_UCP, which changes the behaviour of \b, \d, \s, and \w (and their
37    opposites) so that they make use of Unicode properties. There are also a number
38    of lesser new features, and several bugs have been fixed. A new option,
39    --line-buffered, has been added to pcregrep, for use when it is connected to
40    pipes.
41    
42    
43    Release 8.02 19-Mar-2010
44    ------------------------
45    
46    Another bug-fix release.
47    
48    
49    Release 8.01 19-Jan-2010
50    ------------------------
51    
52    This is a bug-fix release. Several bugs in the code itself and some bugs and
53    infelicities in the build system have been fixed.
54    
55    
56    Release 8.00 19-Oct-09
57    ----------------------
58    
59    Bugs have been fixed in the library and in pcregrep. There are also some
60    enhancements. Restrictions on patterns used for partial matching have been
61    removed, extra information is given for partial matches, the partial matching
62    process has been improved, and an option to make a partial match override a
63    full match is available. The "study" process has been enhanced by finding a
64    lower bound matching length. Groups with duplicate numbers may now have
65    duplicated names without the use of PCRE_DUPNAMES. However, they may not have
66    different names. The documentation has been revised to reflect these changes.
67    The version number has been expanded to 3 digits as it is clear that the rate
68    of change is not slowing down.
69    
70    
71  Release 7.3 20-Aug-07  Release 7.9 11-Apr-09
72    ---------------------
73    
74    Mostly bugfixes and tidies with just a couple of minor functional additions.
75    
76    
77    Release 7.8 05-Sep-08
78    ---------------------
79    
80    More bug fixes, plus a performance improvement in Unicode character property
81    lookup.
82    
83    
84    Release 7.7 07-May-08
85    ---------------------
86    
87    This is once again mainly a bug-fix release, but there are a couple of new
88    features.
89    
90    
91    Release 7.6 28-Jan-08
92    ---------------------
93    
94    The main reason for having this release so soon after 7.5 is because it fixes a
95    potential buffer overflow problem in pcre_compile() when run in UTF-8 mode. In
96    addition, the CMake configuration files have been brought up to date.
97    
98    
99    Release 7.5 10-Jan-08
100    ---------------------
101    
102    This is mainly a bug-fix release. However the ability to link pcregrep with
103    libz or libbz2 and the ability to link pcretest with libreadline have been
104    added. Also the --line-offsets and --file-offsets options were added to
105    pcregrep.
106    
107    
108    Release 7.4 21-Sep-07
109    ---------------------
110    
111    The only change of specification is the addition of options to control whether
112    \R matches any Unicode line ending (the default) or just CR, LF, and CRLF.
113    Otherwise, the changes are bug fixes and a refactoring to reduce the number of
114    relocations needed in a shared library. There have also been some documentation
115    updates, in particular, some more information about using CMake to build PCRE
116    has been added to the NON-UNIX-USE file.
117    
118
