2  ------------------------  ------------------------
3    
4  Release 8.10 03-Jun-2010  Release 8.32 xx-xxxx-2012
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.

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  ------------------------  ------------------------
