2  ------------------------  ------------------------
3    
4    Release 8.13 16-Aug-2011
5    ------------------------
6    
7    This is mainly a bug-fix release. There has been a lot of internal refactoring.
8    The Unicode tables have been updated. The only new feature in the library is
9    the passing of *MARK information to callouts. Some additions have been made to
10    pcretest to make testing easier and more comprehensive. There is a new option
11    for pcregrep to adjust its internal buffer size.
12    
13    
14    Release 8.12 15-Jan-2011
15    ------------------------
16    
17    This release fixes some bugs in pcregrep, one of which caused the tests to fail
18    on 64-bit big-endian systems. There are no changes to the code of the library.
19    
20    
21    Release 8.11 10-Dec-2010
22    ------------------------
23    
24    A number of bugs in the library and in pcregrep have been fixed. As always, see
25    ChangeLog for details. The following are the non-bug-fix changes:
26    
27    . Added --match-limit and --recursion-limit to pcregrep.
28    
29    . Added an optional parentheses number to the -o and --only-matching options
30      of pcregrep.
31    
32    . Changed the way PCRE_PARTIAL_HARD affects the matching of $, \z, \Z, \b, and
33      \B.
34    
35    . Added PCRE_ERROR_SHORTUTF8 to make it possible to distinguish between a
36      bad UTF-8 sequence and one that is incomplete when using PCRE_PARTIAL_HARD.
37    
38    . Recognize (*NO_START_OPT) at the start of a pattern to set the PCRE_NO_
39      START_OPTIMIZE option, which is now allowed at compile time
40    
41    
42    Release 8.10 25-Jun-2010
43    ------------------------
44    
45    There are two major additions: support for (*MARK) and friends, and the option
46    PCRE_UCP, which changes the behaviour of \b, \d, \s, and \w (and their
47    opposites) so that they make use of Unicode properties. There are also a number
48    of lesser new features, and several bugs have been fixed. A new option,
49    --line-buffered, has been added to pcregrep, for use when it is connected to
50    pipes.
51    
52    
53    Release 8.02 19-Mar-2010
54    ------------------------
55    
56    Another bug-fix release.
57    
58    
59    Release 8.01 19-Jan-2010
60    ------------------------
61    
62    This is a bug-fix release. Several bugs in the code itself and some bugs and
63    infelicities in the build system have been fixed.
64    
65    
66    Release 8.00 19-Oct-09
67    ----------------------
68    
69  Release 7.3 16-Aug-07  Bugs have been fixed in the library and in pcregrep. There are also some
70    enhancements. Restrictions on patterns used for partial matching have been
71    removed, extra information is given for partial matches, the partial matching
72    process has been improved, and an option to make a partial match override a
73    full match is available. The "study" process has been enhanced by finding a
74    lower bound matching length. Groups with duplicate numbers may now have
75    duplicated names without the use of PCRE_DUPNAMES. However, they may not have
76    different names. The documentation has been revised to reflect these changes.
77    The version number has been expanded to 3 digits as it is clear that the rate
78    of change is not slowing down.
79    
80    
81    Release 7.9 11-Apr-09
82    ---------------------
83    
84    Mostly bugfixes and tidies with just a couple of minor functional additions.
85    
86    
87    Release 7.8 05-Sep-08
88    ---------------------
89    
90    More bug fixes, plus a performance improvement in Unicode character property
91    lookup.
92    
93    
94    Release 7.7 07-May-08
95    ---------------------
96    
97    This is once again mainly a bug-fix release, but there are a couple of new
98    features.
99    
100    
101    Release 7.6 28-Jan-08
102    ---------------------
103    
104    The main reason for having this release so soon after 7.5 is because it fixes a
105    potential buffer overflow problem in pcre_compile() when run in UTF-8 mode. In
106    addition, the CMake configuration files have been brought up to date.
107    
108    
109    Release 7.5 10-Jan-08
110    ---------------------
111    
112    This is mainly a bug-fix release. However the ability to link pcregrep with
113    libz or libbz2 and the ability to link pcretest with libreadline have been
114    added. Also the --line-offsets and --file-offsets options were added to
115    pcregrep.
116    
117    
118    Release 7.4 21-Sep-07
119    ---------------------
120    
121    The only change of specification is the addition of options to control whether
122    \R matches any Unicode line ending (the default) or just CR, LF, and CRLF.
123    Otherwise, the changes are bug fixes and a refactoring to reduce the number of
124    relocations needed in a shared library. There have also been some documentation
125    updates, in particular, some more information about using CMake to build PCRE
126    has been added to the NON-UNIX-USE file.
127    
128    
129    Release 7.3 28-Aug-07
130  ---------------------  ---------------------
131    
132  Most changes are bug fixes. Some that are not:  Most changes are bug fixes. Some that are not:

144    4. When CRLF is a valid line-ending sequence, pcre_exec() and pcre_dfa_exec()
145       no longer advance by two characters instead of one when an unanchored match
146       fails at CRLF if there are explicit CR or LF matches within the pattern.
147       This gets rid of some anomalous effects that previously occurred.
148    
149    5. Some PCRE-specific settings for varying the newline options at the start of
150       a pattern have been added.
