Some interesting minor changes here:

Death-on-downed chance now applies to several non damage health state changes. (Heatstroke, hypothermia, tox gas, lung rot) - can't use hotbox to guarantee loads of prisoners anymore.

Things to load into transport pods can now be changed at any time. - modify pod contents mid-load!

Loudspeakers and lightballs can now be switched on and off. - no more uninstalling to save power.
