In addition to a broken release of brotli (where enc/dec don't specify -lbrotlicommon, even on trunk, for openssl and other consumers to ferret out that binding), and lots of fun changes to build flags in curl 7.81 minor release (who does that?) there appears to be one test failure with date formatting in httpd 2.4.x branch (including release 2.4.52) and apr 1.7.x branch (including release 1.7.0);
t/modules/include.t ................. 56/98 # Failed test 64 in t/modules/include.t at line 373 Have not had time to investigate whether this is a change in perl behavior, or possibly a regression caused by apr datetime handling in 1.7.x itself., but any release apr-side should hold off just a bit to resolve this question. And there's the issue of pcre 8.x sources no longer available for download from ftp.pcre.org. While they still exist, there's already been one security release that ignored pcre 8.x considerations, so pcre 10.x obviously can't wait for httpd release from trunk.
