 Version: 3.0.43
 Date: ???
   Changes:
+    - Remade tech tree with autotech 2.0. Science pack cost comparasion:
+    - automation: n/a -> trigger
+    - py1: 100 -> 100
+    - logi: 360 -> 300
+    - py2: 1300 -> 800
+    - chem: 2000 -> 1400
+    - py3: 2250 -> 1750
+    - prod: 1750 -> 2250
+    - py4: 2250 -> 3000
+    - utility: 1500 -> 3300
+    - space: 1000 -> 3600
+    - phyrric: 3000 -> 8000
+    - Tuned down the exponential ramping on worker robot speed from 2^N to 1.5^N.
     - Many typos fixed and some new translations in DE locale including the py codex.
     - Fix lockup trying to calculate spoilage possibilities of hidden items.
     - Improved generator autofill to evenly distribute stacks of fuels. Resolves https://github.com/pyanodon/pybugreports/issues/1085
