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:

Feedback for 27.0.91 pretest from bcallah@, matthieu@, krw@
Feedback for 27.1 from Nam Nguyen, ok krw@
there may be some missing as my unpacked ports source is a little out of date
but this should catch the main things people might run into
the struct was reordered a second time in sysctl.h r1.192 to improve
compatibility but amd64 snapshot packages made it out before that happened
so the bumps are still needed

Many thanks to all the folks who tested the pretest and rc tarballs.
Release tested by Gregoire Jadi, Markus Hennecke, krw@ and solene@ on
amd64, sparc64, powerpc, armv7 and arm64. ok krw@ solene@
Mostly a bug-fixe release, see NEWS for the few things that changed.
The diff for bug #24082 included is in this release.
Tested on armv7 and amd64. -rc/release test reports from alf, Manuel
Giraud, sunil@ and krw@
Most likely due to the switch to binutils-2.17, emacs crashes with SIGBUS
at the loadup build step on sparc64, because it puts the section headers
at an unaligned address.
I am not sure whether this is the True Proper Fix. Also, other strict
architectures ought to be affected too. But let's at least provide
a working emacs package for sparc64 users at c2k15.
To be revisited laterwith feedback from upstream.
Problem reported by sthen/dlg/naddy.
Lots of test reports on amd64, sparc64, loongson, and hppa by
Alf Schlichting, bcallah@ and juanfra@. Many thanks!
