+
+- replaced green/red dots in the Blizzard with arrows
+- spawn sound for Wind Crows
+- updated the translations
+- the conformal/history menu is split into "models of hyperbolic geometry" and "history menu"
+- improved the automatic rotation system in "models of hyperbolic geometry"
+- lower halfplane option added (works better in the Ivory Tower than upper halfplane)
+- four new models in "models of hyperbolic geometry"; improved the old ones (especially the 3D effects are now 'correct', except that they assume that the ground is a hyperbolic plane)
+- when changing the sight range, overgenerate works immediately now.
