5    -------------------------
6    
7    .  A number of issues in pcregrep have been fixed, making it more compatible
8       with GNU grep. In particular, --exclude and --include (and variants) apply
9       to all files now, not just those obtained from scanning a directory
10       recursively. In Windows environments, the default action for directories is
11       now "skip" instead of "read" (which provokes an error).
12    
13    
14    Release 8.31 06-July-2012
15    -------------------------
16    
17    This is mainly a bug-fixing release, with a small number of developments:
18    
19    . The JIT compiler now supports partial matching and the (*MARK) and
20      (*COMMIT) verbs.
21    
22    . PCRE_INFO_MAXLOOKBEHIND can be used to find the longest lookbehind in a
23      pattern.
24    
25    . There should be a performance improvement when using the heap instead of the
26      stack for recursion.
27    
28    . pcregrep can now be linked with libedit as an alternative to libreadline.
29    
30    . pcregrep now has a --file-list option where the list of files to scan is
31      given as a file.
32    
33    . pcregrep now recognizes binary files and there are related options.
34    
35    . The Unicode tables have been updated to 6.1.0.
36    
37    As always, the full list of changes is in the ChangeLog file.
38    
39    
40    Release 8.30 04-February-2012
41    -----------------------------
42    
43    Release 8.30 introduces a major new feature: support for 16-bit character
44    strings, compiled as a separate library. There are a few changes to the
45    8-bit library, in addition to some bug fixes.
46    
47    . The pcre_info() function, which has been obsolete for over 10 years, has
48      been removed.
49    
50    . When a compiled pattern was saved to a file and later reloaded on a host
51      with different endianness, PCRE used automatically to swap the bytes in some
52      of the data fields. With the advent of the 16-bit library, where more of this
53      swapping is needed, it is no longer done automatically. Instead, the bad
54      endianness is detected and a specific error is given. The user can then call
55      a new function called pcre_pattern_to_host_byte_order() (or an equivalent
56      16-bit function) to do the swap.
57    
58    . In UTF-8 mode, the values 0xd800 to 0xdfff are not legal Unicode
59      code points and are now faulted. (They are the so-called "surrogates"
60      that are reserved for coding high values in UTF-16.)
61    
62    
63    Release 8.21 12-Dec-2011
64    ------------------------
65    
66    This is almost entirely a bug-fix release. The only new feature is the ability
67    to obtain the size of the memory used by the JIT compiler.
68    
69    
70    Release 8.20 21-Oct-2011
71    ------------------------
72    
73    The main change in this release is the inclusion of Zoltan Herczeg's
74    just-in-time compiler support, which can be accessed by building PCRE with
75    --enable-jit. Large performance benefits can be had in many situations. 8.20
76    also fixes an unfortunate bug that was introduced in 8.13 as well as tidying up
77    a number of infelicities and differences from Perl.
78    
79    
80    Release 8.13 16-Aug-2011
81    ------------------------
82    
83    This is mainly a bug-fix release. There has been a lot of internal refactoring.
84    The Unicode tables have been updated. The only new feature in the library is
85    the passing of *MARK information to callouts. Some additions have been made to
86    pcretest to make testing easier and more comprehensive. There is a new option
87    for pcregrep to adjust its internal buffer size.
88    
89    
90    Release 8.12 15-Jan-2011
91    ------------------------
92    
93    This release fixes some bugs in pcregrep, one of which caused the tests to fail
94    on 64-bit big-endian systems. There are no changes to the code of the library.
95    
96    
97    Release 8.11 10-Dec-2010
98    ------------------------
99    
100    A number of bugs in the library and in pcregrep have been fixed. As always, see
101    ChangeLog for details. The following are the non-bug-fix changes:
102    
103    . Added --match-limit and --recursion-limit to pcregrep.
104    
105    . Added an optional parentheses number to the -o and --only-matching options
106      of pcregrep.
107    
108    . Changed the way PCRE_PARTIAL_HARD affects the matching of $, \z, \Z, \b, and
109      \B.
110    
111    . Added PCRE_ERROR_SHORTUTF8 to make it possible to distinguish between a
112      bad UTF-8 sequence and one that is incomplete when using PCRE_PARTIAL_HARD.
113    
114    . Recognize (*NO_START_OPT) at the start of a pattern to set the PCRE_NO_
115      START_OPTIMIZE option, which is now allowed at compile time
116    
117    
118    Release 8.10 25-Jun-2010
119    ------------------------
120    
121    There are two major additions: support for (*MARK) and friends, and the option
122    PCRE_UCP, which changes the behaviour of \b, \d, \s, and \w (and their
123    opposites) so that they make use of Unicode properties. There are also a number
124    of lesser new features, and several bugs have been fixed. A new option,
125    --line-buffered, has been added to pcregrep, for use when it is connected to
126    pipes.
127    
128    
129    Release 8.02 19-Mar-2010
130    ------------------------
131    
132    Another bug-fix release.
133    
134    
135    Release 8.01 19-Jan-2010
136    ------------------------
137    
138    This is a bug-fix release. Several bugs in the code itself and some bugs and
139    infelicities in the build system have been fixed.
140    
141    
142    Release 8.00 19-Oct-09
143    ----------------------
144    
145    Bugs have been fixed in the library and in pcregrep. There are also some
146    enhancements. Restrictions on patterns used for partial matching have been
147    removed, extra information is given for partial matches, the partial matching
148    process has been improved, and an option to make a partial match override a
149    full match is available. The "study" process has been enhanced by finding a
150    lower bound matching length. Groups with duplicate numbers may now have
151    duplicated names without the use of PCRE_DUPNAMES. However, they may not have
152    different names. The documentation has been revised to reflect these changes.
153    The version number has been expanded to 3 digits as it is clear that the rate
154    of change is not slowing down.
155    
156    
157    Release 7.9 11-Apr-09
158    ---------------------
159    
160    Mostly bugfixes and tidies with just a couple of minor functional additions.
161    
162    
163    Release 7.8 05-Sep-08
164    ---------------------
165    
166    More bug fixes, plus a performance improvement in Unicode character property
167    lookup.
168    
169    
170    Release 7.7 07-May-08
171    ---------------------
172    
173    This is once again mainly a bug-fix release, but there are a couple of new
174    features.
175    
176    
177    Release 7.6 28-Jan-08
