Release Notes: Several bugs in the code are mended, and some problems and infelicities in the build system have been tidied up.
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.
Release Notes: The changes for this release are mainly bugfixes, though there are one or two small additional features.
Release Notes: This release contains a major new feature, support for 16-bit character strings by means of a second library which can be compiled instead of, or as well as, the 8-bit library. Other changes are mainly bugfixes and tidies.
Release Notes: This is a bugfix release.
