addedNewly added Standard gravity planetary value is going to replace the planet mass as life potential direct factor soon. However, the planet mass remains major factor contributing to final gravity value. This is pretty much going to open up new ways to interact with planet potential by influencing its geology.
addedAdded a new Biosphere tutorial step explaining Spark of Life, Support Growth, Cull Population, and the importance of inspecting Life Potential before trying to seed life.
fixedFixed planetary temperature unit display in Life Potential blockers.
addedAdded a new Biosphere temperature tooltip showing how surface temperature is shaped by stellar heating and planetary core heat.
addedAdded planet mass readout to the Geology panel.
addedAdded Standard Gravity display to the Geology panel, showing each rocky planet's estimated surface gravity relative to Earth.
