New projects are advised to use the new PCRE2 libraries. Release 8.44 12-February-2020 ----------------------------- This is a bug-fix release. Release 8.43 23-February-2019 ----------------------------- This is a bug-fix release. Release 8.42 20-March-2018 -------------------------- This is a bug-fix release. Release 8.41 13-June-2017 ------------------------- This is a bug-fix release. Release 8.40 11-January-2017 ---------------------------- This is a bug-fix release. Release 8.39 14-June-2016 ------------------------- Some appropriate PCRE2 JIT improvements have been retro-fitted to PCRE1. Apart from that, this is another bug-fix release. Note that this library (now called PCRE1) is now being maintained for bug fixes only. New projects are advised to use the new PCRE2 libraries. Release 8.38 23-November-2015 ----------------------------- This is bug-fix release. Note that this library (now called PCRE1) is now being maintained for bug fixes only. New projects are advised to use the new PCRE2 libraries. Release 8.37 28-April-2015 -------------------------- This is bug-fix release. Note that this library (now called PCRE1) is now being maintained for bug fixes only. New projects are advised to use the new PCRE2 libraries. Release 8.36 26-September-2014 ------------------------------ This is primarily a bug-fix release. However, in addition, the Unicode data tables have been updated to Unicode 7.0.0. Release 8.35 04-April-2014 -------------------------- There have been performance improvements for classes containing non-ASCII characters and the "auto-possessification" feature has been extended. Other minor improvements have been implemented and bugs fixed. There is a new callout feature to enable applications to do detailed stack checks at compile time, to avoid running out of stack for deeply nested parentheses. The JIT compiler has been extended with experimental support for ARM-64, MIPS-64, and PPC-LE. Release 8.34 15-December-2013 ----------------------------- As well as fixing the inevitable bugs, performance has been improved by refactoring and extending the amount of "auto-possessification" that PCRE does. Other notable changes: . Implemented PCRE_INFO_MATCH_EMPTY, which yields 1 if the pattern can match an empty string. If it can, pcretest shows this in its information output. . A back reference to a named subpattern when there is more than one of the same name now checks them in the order in which they appear in the pattern. The first one that is set is used for the reference. Previously only the first one was inspected. This change makes PCRE more compatible with Perl. . Unicode character properties were updated from Unicode 6.3.0. . The character VT has been added to the set of characters that match \s and are generally treated as white space, following this same change in Perl 5.18. There is now no difference between "Perl space" and "POSIX space". . Perl has changed its handling of \8 and \9. If there is no previously encountered capturing group of those numbers, they are treated as the literal characters 8 and 9 instead of a binary zero followed by the literals. PCRE now does the same. . Following Perl, added \o{} to specify codepoints in octal, making it possible to specify values greater than 0777 and also making them unambiguous. . In UCP mode, \s was not matching two of the characters that Perl matches, namely NEL (U+0085) and MONGOLIAN VOWEL SEPARATOR (U+180E), though they were matched by \h. . Add JIT support for the 64 bit TileGX architecture. . Upgraded the handling of the POSIX classes [:graph:], [:print:], and [:punct:] when PCRE_UCP is set so as to include the same characters as Perl does in Unicode mode. . Perl no longer allows group names to start with digits, so I have made this change also in PCRE. . A
