The most prominent change for us is probably the new portable dumper,
emacs no longer modifies the layout of its ELF executable as part of its
dumping mechanism. No more sbrk-based allocator at build time, no more
nopie or ld -Z workarounds, etc.
From the release announce email:

make sure a package can be generated and the installed package is
correct. Remove attempt at updating dir -- emacs install always
clobbers the existing dir and the texinfo files do not have the
required info to be processed by install-info
