@@ -3993,3 +3993,16 @@ bugfixes:
 - fixed incorrect farlands generation in quotient geometries
 - fixed incorrect wall shape in some geometries (e.g. Euclidean)
 - fixed a bug in 16-cell
+
+2020-05-31 16:47 Update 11.3o:
+
+- new commands for tes files: cscale, repeat
+- texture mode now compatible with tes files
+- more detailed explanation if the polygon does not end
+- in texture mode, relabeled "zoom/scale" to correct "scale/rotate"
+- parser: edge_angles function
+- fake curvature: not works in 2D; improved net showing; new options
+- Nil: fixed the raycaster, and a freeze when changing the 'width' parameter
+- fixed a crash when changing wall quality in some geometries
+- when selecting singlecolor/randomcolor pattern in 3D, you can now specify the wall probability
