action when "Power is critically low". The choices are "Hibernate" or
"Power off". Often Hibernate is a disabled option because of problems
with hibernate on various systems.

option is no longer present.
There are some deletions from the ui file and some corresponding code deletions from the associated c file (cc-power-panel.c).
It is possible that extra code has been removed that could cause a
crash or affect other options in the power panel.
However, the changes are fairly small and easy to review. Nothing
looks out of place. Also testing has not shown any problems.
