1  News about PCRE releases  News about PCRE releases
2  ------------------------  ------------------------
3    
4    Release 8.30
5    ------------
6    
7    Release 8.30 introduces a major new feature: support for 16-bit character
8    strings, compiled as a separate library. There are a few changes to the
9    8-bit library, in addition to some bug fixes.
10    
11    . The pcre_info() function, which has been obsolete for over 10 years, has
12      been removed.
13    
14    . When a compiled pattern was saved to a file and later reloaded on a host
15      with different endianness, PCRE used automatically to swap the bytes in some
16      of the data fields. With the advent of the 16-bit library, where more of this
17      swapping is needed, it is no longer done automatically. Instead, the bad
18      endianness is detected and a specific error is given. The user can then call
19      a new function called pcre_pattern_to_host_byte_order() (or an equivalent
20      16-bit function) to do the swap.
21    
22    . In UTF-8 mode, the values 0xd800 to 0xdfff are not legal Unicode
23      code points and are now faulted. (They are the so-called "surrogates"
24      that are reserved for coding high values in UTF-16.)
25    
26    
27    Release 8.21 12-Dec-2011
28    ------------------------
29    
30    This is almost entirely a bug-fix release. The only new feature is the ability
31    to obtain the size of the memory used by the JIT compiler.
32    
33    
34    Release 8.20 21-Oct-2011
35    ------------------------
36    
37    The main change in this release is the inclusion of Zoltan Herczeg's
38    just-in-time compiler support, which can be accessed by building PCRE with
39    --enable-jit. Large performance benefits can be had in many situations. 8.20
40    also fixes an unfortunate bug that was introduced in 8.13 as well as tidying up
41    a number of infelicities and differences from Perl.
42    
43    
44    Release 8.13 16-Aug-2011
45    ------------------------
46    
47    This is mainly a bug-fix release. There has been a lot of internal refactoring.
48    The Unicode tables have been updated. The only new feature in the library is
49    the passing of *MARK information to callouts. Some additions have been made to
50    pcretest to make testing easier and more comprehensive. There is a new option
51    for pcregrep to adjust its internal buffer size.
52    
53    
54    Release 8.12 15-Jan-2011
55    ------------------------
56    
57    This release fixes some bugs in pcregrep, one of which caused the tests to fail
58    on 64-bit big-endian systems. There are no changes to the code of the library.
59    
60    
61    Release 8.11 10-Dec-2010
62    ------------------------
63    
64    A number of bugs in the library and in pcregrep have been fixed. As always, see
65    ChangeLog for details. The following are the non-bug-fix changes:
66    
67    . Added --match-limit and --recursion-limit to pcregrep.
68    
69    . Added an optional parentheses number to the -o and --only-matching options
70      of pcregrep.
71    
72    . Changed the way PCRE_PARTIAL_HARD affects the matching of $, \z, \Z, \b, and
73      \B.
74    
75    . Added PCRE_ERROR_SHORTUTF8 to make it possible to distinguish between a
76      bad UTF-8 sequence and one that is incomplete when using PCRE_PARTIAL_HARD.
77    
78    . Recognize (*NO_START_OPT) at the start of a pattern to set the PCRE_NO_
79      START_OPTIMIZE option, which is now allowed at compile time
80    
81    
82    Release 8.10 25-Jun-2010
83    ------------------------
84    
85    There are two major additions: support for (*MARK) and friends, and the option
86    PCRE_UCP, which changes the behaviour of \b, \d, \s, and \w (and their
87    opposites) so that they make use of Unicode properties. There are also a number
88    of lesser new features, and several bugs have been fixed. A new option,
89    --line-buffered, has been added to pcregrep, for use when it is connected to
90    pipes.
91    
92    
93    Release 8.02 19-Mar-2010
94    ------------------------
95    
96    Another bug-fix release.
97    
98    
99    Release 8.01 19-Jan-2010
100    ------------------------
101    
102    This is a bug-fix release. Several bugs in the code itself and some bugs and
103    infelicities in the build system have been fixed.
104    
105    
106    Release 8.00 19-Oct-09
107    ----------------------
108    
109    Bugs have been fixed in the library and in pcregrep. There are also some
110    enhancements. Restrictions on patterns used for partial matching have been
111    removed, extra information is given for partial matches, the partial matching
112    process has been improved, and an option to make a partial match override a
113    full match is available. The "study" process has been enhanced by finding a
114    lower bound matching length. Groups with duplicate numbers may now have
115    duplicated names without the use of PCRE_DUPNAMES. However, they may not have
116    different names. The documentation has been revised to reflect these changes.
117    The version number has been expanded to 3 digits as it is clear that the rate
118    of change is not slowing down.
119
