Version 8.12 of PCRE

Release Notes: This release contains several bug fixes for the pcregrep program. There are no changes to the code of the PCRE library.

Other releases

Release Notes: 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 Notes: Performance has been improved by extending the "auto-possessification" feature. Backreferences to named subpatterns now check all with the same name; this and other changes improve compatibility with Perl. A number of bugs have been mended.

Release Notes: The Just-In-Time compiler (JIT) now supports all pattern features, including callouts and the backtracking verbs. In addition, some bugs are fixed and there are minor performance enhancements.

Release Notes: Support for 32-bit characters strings and UTF-32 has been added. Unicode compatibility has been improved for \X (it now matches extended grapheme clusters) and for characters such as Greek sigma that have more than one "other case". The Unicode tables are updated to 6.2.0. Matching using the JIT compiler has been sped up in some cases. There are some extensions to pcregrep and, as always, bugs have been fixed.
