a. is incorrect. We updated UPower, and not gnome-settings-daemon or
gnome-control-center.

UPower is now responsible for what to do when the battery level is too low.
In /etc/UPower/UPower.conf it says:
# The action to take when "TimeAction" or "PercentageAction" above has been
# reached for the batteries (UPS or laptop batteries) supplying the computer
#
# Possible values are:
# PowerOff
# Hibernate
# HybridSleep
#
# If HybridSleep isn't available, Hibernate will be used
# If Hibernate isn't available, PowerOff will be used
CriticalPowerAction=HybridSleep

This isn't a user option anymore, and there's no code in gnome-settings-daemon
to handle it.

I filed this bug about it:
https://bugzilla.gnome.org/show_bug.cgi?id=749436

It's not a blocker though, as it's "just as broken in F21".
