I have just put a release candidate for 10.23 here: ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Testing/pcre2-10.23-RC1.tar.gz ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Testing/pcre2-10.23-RC1.tar.bz2 ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Testing/pcre2-10.23-RC1.zip
There are the usual bug fixes and two minor extensions (see NEWS). The main change, however, is a seriously large refactoring of the pcre2_compile() function. This was overdue after nearly 20 years of hacking development because the code had got very messy and hard to understand in places. The output from pcre2_compile() should be identical to what it was before, but the internals are cleaner and some unnecessary duplication has been got rid of. It seems to run slightly faster too, which is a bonus. Since the code was first committed to the repository it has been tested a lot by fuzzers (and bugs have been fixed), so I believe it is in good shape. Nevertheless, as there has been so much change, I'd be grateful if as many people as possible could run tests in the next few weeks. ADVANCE HEADS-UP: Once 10.23 is out and settled, I'll be integrating work I'm doing on pcre2_match() - a similar large tidying up and refactoring. The new code no longer uses the system stack for remembering backtracking points by recursive function calls (this has been the cause of many issues over the years). Using a private "stack" will make it possible to be more Perl-compatible in several ways, including backtracking into recursions in the pattern. All this is planned for a subsequent release in about 6 months time. I'll probably call it 10.30 because there will be some noticeable changes.
