4  Release 8.10 03-Jun-2010  Release 8.31 20-June-2012
5    -------------------------
6    
7    This is mainly a bug-fixing release, with a small number of developments:
8    
9    . The JIT compiler now supports partial matching and the (*MARK) and
10      (*COMMIT) verbs.
11    
12    . PCRE_INFO_MAXLOOKBEHIND can be used to find the longest lookbehing in a
13      pattern.
14    
15    . There should be a performance improvement when using the heap instead of the
16      stack for recursion.
17    
18    . pcregrep can now be linked with libedit as an alternative to libreadline.
19    
20    . pcregrep now has a --file-list option where the list of files to scan is
21      given as a file.
22    
23    . pcregrep now recognizes binary files and there are related options.
24    
25    . The Unicode tables have been updated to 6.1.0.
26    
27    As always, the full list of changes is in the ChangeLog file.

30    Release 8.30 04-February-2012
31    -----------------------------
32    
33    Release 8.30 introduces a major new feature: support for 16-bit character
34    strings, compiled as a separate library. There are a few changes to the
35    8-bit library, in addition to some bug fixes.
36    
37    . The pcre_info() function, which has been obsolete for over 10 years, has
38      been removed.
39    
40    . When a compiled pattern was saved to a file and later reloaded on a host
41      with different endianness, PCRE used automatically to swap the bytes in some
42      of the data fields. With the advent of the 16-bit library, where more of this
43      swapping is needed, it is no longer done automatically. Instead, the bad
44      endianness is detected and a specific error is given. The user can then call
45      a new function called pcre_pattern_to_host_byte_order() (or an equivalent
46      16-bit function) to do the swap.
47    
48    . In UTF-8 mode, the values 0xd800 to 0xdfff are not legal Unicode
49      code points and are now faulted. (They are the so-called "surrogates"
50      that are reserved for coding high values in UTF-16.)
51    
52    
53    Release 8.21 12-Dec-2011
54    ------------------------
55    
56    This is almost entirely a bug-fix release. The only new feature is the ability
57    to obtain the size of the memory used by the JIT compiler.
58    
59    
60    Release 8.20 21-Oct-2011
61    ------------------------
62    
63    The main change in this release is the inclusion of Zoltan Herczeg's
64    just-in-time compiler support, which can be accessed by building PCRE with
65    --enable-jit. Large performance benefits can be had in many situations. 8.20
66    also fixes an unfortunate bug that was introduced in 8.13 as well as tidying up
67    a number of infelicities and differences from Perl.
68    
69    
70    Release 8.13 16-Aug-2011
71    ------------------------
72    
73    This is mainly a bug-fix release. There has been a lot of internal refactoring.
74    The Unicode tables have been updated. The only new feature in the library is
75    the passing of *MARK information to callouts. Some additions have been made to
76    pcretest to make testing easier and more comprehensive. There is a new option
77    for pcregrep to adjust its internal buffer size.
78    
79    
80    Release 8.12 15-Jan-2011
81    ------------------------
82    
83    This release fixes some bugs in pcregrep, one of which caused the tests to fail
84    on 64-bit big-endian systems. There are no changes to the code of the library.
85    
86    
87    Release 8.11 10-Dec-2010
88    ------------------------
89    
90    A number of bugs in the library and in pcregrep have been fixed. As always, see
91    ChangeLog for details. The following are the non-bug-fix changes:
92    
93    . Added --match-limit and --recursion-limit to pcregrep.
94    
95    . Added an optional parentheses number to the -o and --only-matching options
96      of pcregrep.
97    
98    . Changed the way PCRE_PARTIAL_HARD affects the matching of $, \z, \Z, \b, and
99      \B.
100    
101    . Added PCRE_ERROR_SHORTUTF8 to make it possible to distinguish between a
102      bad UTF-8 sequence and one that is incomplete when using PCRE_PARTIAL_HARD.
103    
104    . Recognize (*NO_START_OPT) at the start of a pattern to set the PCRE_NO_
105      START_OPTIMIZE option, which is now allowed at compile time
106    
107    
108    Release 8.10 25-Jun-2010
