To me usrmerge alone would be sufficient to provide new release, but
adding more changes in is a good idea too.

I would like to switch ppc64le profiles to 128-bit IEEE long double ABI
23.0 seems like a good cause to finally tackle it.
This will need some toolchain magic, I will open a bug and block
profile-23.0 tracker.
Fedora finally switched recently
https://fedoraproject.org/wiki/Changes/PPC64LE_Float128_Transition

I tried the switch about a year ago and ran into some trouble with
projects that bundle gnulib.


I'll open a bug and block the tracker.
