     - All caravans can use all caravan outpost types
     - Added a bhoddos to uranium ore phytomining recipe
     - Xeno raising recipes 1-4 are now properly assigned to the corresponding technologies
+    - Caravans now can compare a circuit condition to a static value.
   TURD:
     - Composter TURD path 2 no longer generates methanol. Now it instead generates coalbed gas. Resolves https://github.com/pyanodon/pybugreports/issues/757
     - Redid bioreactor TURD entirely.
