What's new:

• Heat system;
  • Heat going below -50 and above 100 stops the ship from working entirely.
  • Getting close to a star heats up the ship.
  • Burning in a planet's atmosphere heats up the ship.
• 5 new parts;
  • Radiator, removes heat from the ship. Cools down solar and atmospheric heat faster.
  • Heat shield, mitigates damage from atmospheric heat.
  • Propeller, a form of transport within an atmosphere, 100% electric.
  • Probe core, basically the Capsule but without the astronaut, and it consumes electricity.
  • Truss, structural part for the space station lovers.

What's changed:

• Build mode overhaul;
  • Mirror mode now works with staging.
    
  • Each part is separated by categories:
    • Basic
    • Engines
    • Electrical
    • Advanced
• Career Mode balancing;
  • You start with a probe core, and the Gen 1 instead of the Gen 2. The capsule must be unlocked.
• Slight texture changes.
• Bug fixes.

Planned:

• Better target system, so you don't have to click an arrow fifty thousand times.
