The JIT compiler now supports partial matching and the (*MARK) and + (*COMMIT) verbs. + +. PCRE_INFO_MAXLOOKBEHIND can be used to find the longest lookbehing 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 ------------------------ |
