 # New features
 
-pgf-pie now wraps the entire pie into a \scope environment and additionally
-defers lookup of unknown /pgfpie keys to the /pgf and /tikz namespaces. This
-paves the way for all kinds of improvements such as easy setting of global pie
-options like font or placement on the background layer. Further is allows
-referring to the pie as a node via local bounding box and moving the pie around
-on the canvas using the shift key.
+The new option `change direction` will order the slices counterclockwise instead
+of the default clockwise.
 
 # Bug fixes
 
-pgf-pie tokenizes its arguments which led to breakage when used with babel.
-For now, babel functionality is simply disabled for the entire pie.
-
+The `\pie`command did not escape spaces properly which prevented using options
+starting with a spaces. #14
