I upgraded the temperature calculation on planets. It now taken into account the internal heat and tidal heating of a nearby objects. So it is possible to find such exotic places like this temperate terra moon orbiting a gas giant that is 93 AU away from a pair of dim white and brown dwarves. Without tidal heating, this moon would be extremely cold, at only 22 K.
ESI is now stable, not changing with time, because it uses average planet temperature value, not the current one.
Upgraded solar spots. I don't like their appearance though (the filaments are actually elongated granule, not a straight lines like here), this may be changed before release or in future versions.
