2  ------------------------  ------------------------
3    
4    Release 8.11 10-Dec-2010
5    ------------------------
6    
7    A number of bugs in the library and in pcregrep have been fixed. As always, see
8    ChangeLog for details. The following are the non-bug-fix changes:
9    
10    . Added --match-limit and --recursion-limit to pcregrep.
11    
12    . Added an optional parentheses number to the -o and --only-matching options
13      of pcregrep.
14    
15    . Changed the way PCRE_PARTIAL_HARD affects the matching of $, \z, \Z, \b, and
16      \B.
17    
18    . Added PCRE_ERROR_SHORTUTF8 to make it possible to distinguish between a
19      bad UTF-8 sequence and one that is incomplete when using PCRE_PARTIAL_HARD.
20    
21    . Recognize (*NO_START_OPT) at the start of a pattern to set the PCRE_NO_
22      START_OPTIMIZE option, which is now allowed at compile time
23    
24  Release 7.3 16-Aug-07  
25    Release 8.10 25-Jun-2010
26    ------------------------
27    
28    There are two major additions: support for (*MARK) and friends, and the option
29    PCRE_UCP, which changes the behaviour of \b, \d, \s, and \w (and their
30    opposites) so that they make use of Unicode properties. There are also a number
31    of lesser new features, and several bugs have been fixed. A new option,
32    --line-buffered, has been added to pcregrep, for use when it is connected to
33    pipes.
34    
35    
36    Release 8.02 19-Mar-2010
37    ------------------------
38    
39    Another bug-fix release.
40    
41    
42    Release 8.01 19-Jan-2010
43    ------------------------
44    
45    This is a bug-fix release. Several bugs in the code itself and some bugs and
46    infelicities in the build system have been fixed.
47    
48    
49    Release 8.00 19-Oct-09
50    ----------------------
51    
52    Bugs have been fixed in the library and in pcregrep. There are also some
53    enhancements. Restrictions on patterns used for partial matching have been
54    removed, extra information is given for partial matches, the partial matching
55    process has been improved, and an option to make a partial match override a
56    full match is available. The "study" process has been enhanced by finding a
57    lower bound matching length. Groups with duplicate numbers may now have
58    duplicated names without the use of PCRE_DUPNAMES. However, they may not have
59    different names. The documentation has been revised to reflect these changes.
60    The version number has been expanded to 3 digits as it is clear that the rate
61    of change is not slowing down.
62    
63    
64    Release 7.9 11-Apr-09
65    ---------------------
66    
67    Mostly bugfixes and tidies with just a couple of minor functional additions.
68    
69    
70    Release 7.8 05-Sep-08
71    ---------------------
72    
73    More bug fixes, plus a performance improvement in Unicode character property
74    lookup.
75    
76    
77    Release 7.7 07-May-08
78    ---------------------
79    
80    This is once again mainly a bug-fix release, but there are a couple of new
81    features.
82    
83    
84    Release 7.6 28-Jan-08
85    ---------------------
86    
87    The main reason for having this release so soon after 7.5 is because it fixes a
88    potential buffer overflow problem in pcre_compile() when run in UTF-8 mode. In
89    addition, the CMake configuration files have been brought up to date.
90    
91    
92    Release 7.5 10-Jan-08
93    ---------------------
94    
95    This is mainly a bug-fix release. However the ability to link pcregrep with
96    libz or libbz2 and the ability to link pcretest with libreadline have been
97    added. Also the --line-offsets and --file-offsets options were added to
98    pcregrep.
99    
100    
101    Release 7.4 21-Sep-07
102    ---------------------
103    
104    The only change of specification is the addition of options to control whether
105    \R matches any Unicode line ending (the default) or just CR, LF, and CRLF.
106    Otherwise, the changes are bug fixes and a refactoring to reduce the number of
107    relocations needed in a shared library. There have also been some documentation
108    updates, in particular, some more information about using CMake to build PCRE
109    has been added to the NON-UNIX-USE file.
110    
111    
112    Release 7.3 28-Aug-07
113  ---------------------  ---------------------

127    4. When CRLF is a valid line-ending sequence, pcre_exec() and pcre_dfa_exec()
128       no longer advance by two characters instead of one when an unanchored match
129       fails at CRLF if there are explicit CR or LF matches within the pattern.
130       This gets rid of some anomalous effects that previously occurred.
131    
132    5. Some PCRE-specific settings for varying the newline options at the start of
133       a pattern have been added.
