   Changelog:
   .
-  0.12.0 to 0.13.0:
-  .
-  * More Haddock documenting. 
-  .
-  * @lowerLeftUpperRight@ removed from "Wumpus.Core.BoundingBox".
-  .
-  * Added range checking and Ord obligation to the @bbox@ 
-    \'smart\' constructor.
-  .
-  * Numeric instances for "Wumpus.Core.Colour" improved.
-  .
-  * MatrixMult type class simplified
-  .
-  * Dash Pattern made a list of on-off pairs rather than just a 
-    list 
-  .
-  * The modules - Wumpus.Core.PictureInternal, Wumpus.Core.PostScript,
-    Wumpus.Core.SVG & Wumpus.Core.Utils - are no longer exposed.
-  .
-  * Various operators in "Wumpus.Core.PictureLanguage" changed.
+  0.13.0 to 0.13.1:
   .
-  * Wumpus.Core.TextEncoding split into an internal and a public 
-    module (internal - Wumpus.Core.TextEncodingInternal, public - 
-    Wumpus.Core.TextEncoder).
-
+  * Wumpus.Core.SVG changed path_s to path_c - \'S\' was the 
+    wrongSVG command to match PostScript\'s @curveto@.
