These are +the highlights: + +. There is now support for 32-bit character strings and UTF-32. Like the + 16-bit support, this is done by compiling a separate 32-bit library. + +. \X now matches a Unicode extended grapheme cluster. + +. Case-independent matching of Unicode characters that have more than one + "other case" now makes all three (or more) characters equivalent. This + applies, for example, to Greek Sigma, which has two lowercase versions. + +. Unicode character properties are updated to Unicode 6.2.0. + +. The EBCDIC support, which had decayed, has had a spring clean. + +. A number of JIT optimizations have been added, which give faster JIT + execution speed. In addition, a new direct interface to JIT execution is + available. This bypasses some of the sanity checks of pcre_exec() to give a + noticeable speed-up. + +. A number of issues in pcregrep have been fixed, making it more compatible + with GNU grep. In particular, --exclude and --include (and variants) apply + to all files now, not just those obtained from scanning a directory + recursively. In Windows environments, the default action for directories is + now "skip" instead of "read" (which provokes an error). + +. If the --only-matching (-o) option in pcregrep is specified multiple + times, each one causes appropriate output. For example, -o1 -o2 outputs the + substrings matched by the 1st and 2nd capturing parentheses. A separating + string can be specified by --om-separator (default empty). + +. When PCRE is built via Autotools using a version of gcc that has the + "visibility" feature, it is used to hide internal library functions that are + not part of the public API. + + +Release 8.31 06-July-2012 +------------------------- + +This is mainly a bug-fixing release, with a small number of developments: + +. The JIT compiler now supports partial matching and the (*MARK) and + (*COMMIT) verbs. + +. PCRE_INFO_MAXLOOKBEHIND can be used to find the longest lookbehind in a + pattern. + +. There should be a performance improvement when using the heap instead of the + stack for recursion. + +. pcregrep can now be linked with libedit as an alternative to libreadline. + +. pcregrep now has a --file-list option where the list of files to scan is + given as a file. + +. pcregrep now recognizes binary files and there are related options. + +. The Unicode tables have been updated to 6.1.0. + +As always, the full list of changes is in the ChangeLog file. + + +Release 8.30 04-February-2012 +----------------------------- + +Release 8.30 introduces a major new feature: support for 16-bit character +strings, compiled as a separate library. There are a few changes to the +8-bit library, in addition to some bug fixes. + +. The pcre_info() function, which has been obsolete for over 10 years, has + been removed. + +. When a compiled pattern was saved to a file and later reloaded on a host + with different endianness, PCRE used automatically to swap the bytes in some + of the data fields. With the advent of the 16-bit library, where more of this + swapping is needed, it is no longer done automatically. Instead, the bad + endianness is detected and a specific error is given. The user can then call + a new function called pcre_pattern_to_host_byte_order() (or an equivalent + 16-bit function) to do the swap. + +. In UTF-8 mode, the values 0xd800 to 0xdfff are not legal Unicode + code points and are now faulted. (They are the so-called "surrogates" + that are reserved for coding high values in UTF-16.) + + +Release 8.21 12-Dec-2011 +------------------------ + +This is almost entirely a bug-fix release. The only new feature is the ability +to obtain the size of the memory used by the JIT compiler. + + +Release 8.20 21-Oct-2011 +------------------------ + +The main change in this release is the inclusion of Zoltan Herczeg's +just-in-time compiler support, which can be accessed by building PCRE with +--enable-jit. Large performance benefits can be had in many situations. 8.20 +also fixes an unfortunate bug that was introduced in 8.13 as well as tidying up +a number of infelicities and differences from Perl. + + +Release 8.13 16-Aug-2011 +------------------------ + +This is mainly a bug-fix release. There has been a lot of internal refactoring. +The Unicode tables have been updated. The only new feature in the library is +the passing of *MARK information to callouts. Some additions have been made to +pcretest to make testing easier and more comprehensive. There is a new option +for pcregrep to adjust its internal buffer size. + + Release 8.12 15-Jan-2011 ------------------------ @@ -475,7 +591,7 @@ some of the new functionality in Perl 5.005.
