Improved support for match_limit in JIT.
Code (but not yet documentation) for *LIMIT_MATCH and *LIMIT_RECURSION.
Remove commented code that was accidentally left in.
Use tail recursion in maximizing character and character type repetitions, to reduce stack usage.
Further changes to backtracking verbs in assertions.
Fix COMMIT in recursion; document backtracking verbs in assertions and subroutines.
Code changes for simpler backtracking handling (docs to follow).
Change backtracking behaviour to "first verb encountered".
Fix the case where there are two or more SKIPs that may have to be ignored.
Fix *SKIP infinite loop.
Confine PRUNE and SKIP to recursive subpattern calls, like COMMIT.

Add \p{Xuc} to match characters identifiable by Universal Character Names.
Change some pcre_uchar variables to pcre_uint32 in pcre_exec.c, for better performance.
Pass back the bumpalong value for partial matches.
Fix various save/revert cases for capture_last in recursion and also don't diagnose overflow when it has reverted.
Small tweaks give performance improvements.

File tidies, preparing for 8.32-RC1.
Fix really stupid bug in multicase matching, and deficiency in the tests.
Add PCRE_ERROR_BADLENGTH for a negative length.
JIT native interface.
Previous patch for no stack recursion was incomplete.
Fix typo (duplicate label) when --disable-stack-for-recursion is set.
Lose unused variable warning when UTF not supported.
Clean up compiler warnings for pcre_exec.c in all modes.
pcre32: Fix signed-unsigned compare
pcre32: Use pcre_uint32 for characters
pcre32: exec: Mask bits > 21 in 32-bit UTF mode Allow passing characters with high bits set in UTF-32 mode.
pcre32: exec: Use uint32 for characters
pcre32: More 32-bit cleanliness fixes
pcre32: Add 32-bit library Create libpcre32 that operates on 32-bit characters (UTF-32). This turned out to be surprisingly simple after the UTF-16 support was introduced; mostly just extra ifdefs and adjusting and adding some tests.
Case folding in JIT and removing unnecessary spaces
All the remaining changes for handling characters with more than one other case.
Turn case lists for horizontal and vertical white space into macros so they are defined only once.
General spring-clean of EBCDIC-related issues in the code, which had decayed over time. Also the documentation. Added one test that can be run in an ASCII world to do a little testing of EBCDIC-related things.
Improve extended grapheme clusters using a bit table.
Upgrade \X to match an extended grapheme cluster
Fix capture problem with repeated, empty-string-matching groups.

OP_NOT now supports any UTF character
Set PCRE_EXTRA_USED_JIT when JIT was actually used at runtime. Add /S++ and -s++ to pcretest to show whether JIT was used or not.

Make (*MARK) work in positive assertions.
Add the /= modifier to pcretest so as to be able to check unset capturing parentheses at the ends of patterns.

Tidy the API for _pcre_valid_utf8() to a more suitable form for a future public release. Also make -s in pcretest force a study for every regex.
Refactoring to reduce stack usage for possessively quantified subpatterns. Also fixed a number of bugs related to repeated subpatterns. Some further tidies consequent on the removal of OP_OPT are also in this patch.
