Woohoo! I look forward to it. My thanks and congratulations to all who helped 
with 'core-updates'! :)

My three 'core-updates' patches (which thank you for sprucing the remaining two 
up and committing them!) were from me addressing the main build failures I 
encountered while building my system and home configs against core-updates: 
wine64 and wine64-staging not building due to their dependence on the 32-bit 
(i686-linux) wine and wine-staging packages--the three patches fixed the wine64 
build for me, although building wine-staging (for wine64-staging) hit the 
FFmpeg build failure. After two weeks of bisecting, I tracked it down to commit 
8025d419db which updates binutils from 2.38 to 2.41. I haven't figured out how 
to address the bug but it seems to be from a change between 2.38 and 2.39, as I 
also found a Gentoo bug report hitting the same FFmpeg build error 
(https://bugs.gentoo.org/893118) and downgraded binutils to 2.39 to confirm the 
error is present with that version.

Otherwise, IIRC I didn't encounter any other build failures for x86_64-linux.

Cheers,
Kaelyn
