Excerpt from the release news: Version 10.37 26-May-2021 ------------------------- A few more bug fixes and tidies. The only change of real note is the removal of the actual POSIX names regcomp etc. from the POSIX wrapper library because these have caused issues for some applications (see 10.33 #2 below). Version 10.36 04-December-2020 ------------------------------ Again, mainly bug fixes and tidies. The only enhancements are the addition of GNU grep's -m (aka --max-count) option to pcre2grep, and also unifying the handling of substitution strings for both -O and callouts in pcre2grep, with the addition of $x{...} and $o{...} to allow for characters whose code points are greater than 255 in Unicode mode. NOTE: there is an outstanding issue with JIT support for MacOS on arm64 hardware. For details, please see Bugzilla issue #2618. Signed-off-by: Anatol Belski <ab@php.net>
