 Version: 2.3.0
-Date: ????
+Date: 2026-06-29
   Features:
     - Add an admin-only Surface tab. Admins can create a new blank surface by typing a name; the surface immediately appears in the Surface Cheats target list for every connected player allowed to see other surfaces.
     - Add space-platform creation to the Surface tab (Space Age only). Admins can type a name and pick the planet to orbit; the platform comes up with a hub already placed and its surface immediately appears in the Surface Cheats target list.
     - Add planet-surface creation to the Surface tab (Space Age only). Admins can pick a planet and create its surface; if the surface already exists the action is a harmless no-op, and any newly created surface immediately appears in the Surface Cheats target list.
     - Add a creative wall: an indestructible red wall. Enemies still target and attack it, but it instantly heals back to full and can never be destroyed. It works on any surface, including space platforms, and is enabled by the normal Creative tools' recipe sweep.
     - Add a creative thruster (Space Age only): a thruster that refuels itself every tick, keeping a space platform travelling at vanilla speed with no fuel or oxidizer chain to supply. Place it on a platform, set a route, and it travels with no fuel management.
     - Add an "Asteroid spawning rate" input to the Game Settings cheats (Space Age only): a global multiplier for how often asteroids spawn around space platforms. Default is 1 (vanilla); set it to 0 to stop asteroids spawning entirely. Applies game-wide, not per surface.
+    - "Create Surface → Blank surface" now creates a genuinely flat, empty test surface (no resources, water, cliffs, trees, decoratives, or enemies; always day) with a floor dropdown: Lab tiles, Concrete, or Refined concrete.
+    - Add an "Ignore surface conditions" on/off Surface Cheat that lets planet-gated buildings be placed and planet-gated recipes crafted on the selected surface(s).
   Changes:
     - Move the Surface Cheats menu from the Cheats tab into the Surface tab, grouping it with the surface-creation tools.
