2  ------------------------  ------------------------
3    
4    Release 8.21 05-Dec-2011
5    ------------------------
6    
7    This is mostly a bug-fix release. The only new feature is the ability to obtain
8    the memory used by the JIT compiler.
9    
10    
11    Release 8.20 21-Oct-2011
12    ------------------------
13    
14    The main change in this release is the inclusion of Zoltan Herczeg's
15    just-in-time compiler support, which can be accessed by building PCRE with
16    --enable-jit. Large performance benefits can be had in many situations. 8.20
17    also fixes an unfortunate bug that was introduced in 8.13 as well as tidying up
18    a number of infelicities and differences from Perl.
19    
20    
21    Release 8.13 16-Aug-2011
22    ------------------------
23    
24    This is mainly a bug-fix release. There has been a lot of internal refactoring.
25    The Unicode tables have been updated. The only new feature in the library is
26    the passing of *MARK information to callouts. Some additions have been made to
27    pcretest to make testing easier and more comprehensive. There is a new option
28    for pcregrep to adjust its internal buffer size.
29    
30    
31    Release 8.12 15-Jan-2011
32    ------------------------
33    
34    This release fixes some bugs in pcregrep, one of which caused the tests to fail
35    on 64-bit big-endian systems. There are no changes to the code of the library.
36    
37    
38    Release 8.11 10-Dec-2010
39    ------------------------
40    
41  Release 7.3 16-Aug-07  A number of bugs in the library and in pcregrep have been fixed. As always, see
42    ChangeLog for details. The following are the non-bug-fix changes:
43    
44    . Added --match-limit and --recursion-limit to pcregrep.
45    
46    . Added an optional parentheses number to the -o and --only-matching options
47      of pcregrep.
48    
49    . Changed the way PCRE_PARTIAL_HARD affects the matching of $, \z, \Z, \b, and
50      \B.
51    
52    . Added PCRE_ERROR_SHORTUTF8 to make it possible to distinguish between a
53      bad UTF-8 sequence and one that is incomplete when using PCRE_PARTIAL_HARD.
54    
55    . Recognize (*NO_START_OPT) at the start of a pattern to set the PCRE_NO_
56      START_OPTIMIZE option, which is now allowed at compile time
57    
58    
59    Release 8.10 25-Jun-2010
60    ------------------------
61    
62    There are two major additions: support for (*MARK) and friends, and the option
63    PCRE_UCP, which changes the behaviour of \b, \d, \s, and \w (and their
64    opposites) so that they make use of Unicode properties. There are also a number
65    of lesser new features, and several bugs have been fixed. A new option,
66    --line-buffered, has been added to pcregrep, for use when it is connected to
67    pipes.
68    
69    
70    Release 8.02 19-Mar-2010
71    ------------------------
72    
73    Another bug-fix release.
74    
75    
76    Release 8.01 19-Jan-2010
77    ------------------------
78    
79    This is a bug-fix release. Several bugs in the code itself and some bugs and
80    infelicities in the build system have been fixed.
81    
82    
83    Release 8.00 19-Oct-09
84    ----------------------
85    
86    Bugs have been fixed in the library and in pcregrep. There are also some
87    enhancements. Restrictions on patterns used for partial matching have been
88    removed, extra information is given for partial matches, the partial matching
89    process has been improved, and an option to make a partial match override a
90    full match is available. The "study" process has been enhanced by finding a
91    lower bound matching length. Groups with duplicate numbers may now have
92    duplicated names without the use of PCRE_DUPNAMES. However, they may not have
93    different names. The documentation has been revised to reflect these changes.
94    The version number has been expanded to 3 digits as it is clear that the rate
95    of change is not slowing down.
96    
97    
98    Release 7.9 11-Apr-09
99    ---------------------
100    
101    Mostly bugfixes and tidies with just a couple of minor functional additions.
102    
103    
104    Release 7.8 05-Sep-08
105    ---------------------
106    
107    More bug fixes, plus a performance improvement in Unicode character property
108    lookup.
109    
110    
111    Release 7.7 07-May-08
112    ---------------------
113    
114    This is once again mainly a bug-fix release, but there are a couple of new
115    features.
116    
117    
118    Release 7.6 28-Jan-08
119    ---------------------
120    
121    The main reason for having this release so soon after 7.5 is because it fixes a
122    potential buffer overflow problem in pcre_compile() when run in UTF-8 mode. In
123    addition, the CMake configuration files have been brought up to date.
124    
125    
126    Release 7.5 10-Jan-08
127    ---------------------
128    
129    This is mainly a bug-fix release. However the ability to link pcregrep with
130    libz or libbz2 and the ability to link pcretest with libreadline have been
131    added. Also the --line-offsets and --file-offsets options were added to
132    pcregrep.
133    
134    
135    Release 7.4 21-Sep-07
136    ---------------------
137    
138    The only change of specification is the addition of options to control whether
139    \R matches any Unicode line ending (the default) or just CR, LF, and CRLF.
140    Otherwise, the changes are bug fixes and a refactoring to reduce the number of
141    relocations needed in a shared library. There have also been some documentation
142    updates, in particular, some more information about using CMake to build PCRE
143    has been added to the NON-UNIX-USE file.
144    
145    
146    Release 7.3 28-Aug-07
147  ---------------------  ---------------------
148    
149  Most changes are bug fixes. Some that are not:  Most changes are bug fixes. Some that are not:

161    4. When CRLF is a valid line-ending sequence, pcre_exec() and pcre_dfa_exec()
162       no longer advance by two characters instead of one when an unanchored match
163       fails at CRLF if there are explicit CR or LF matches within the pattern.
164       This gets rid of some anomalous effects that previously occurred.
165    
166    5. Some PCRE-specific settings for varying the newline options at the start of
167       a pattern have been added.
