version 0.99.4 (not yet released)
+ * add fix_aspect kwarg to Basemap.__init__, when true
+ axes.set_aspect is set to 'auto' instead of default 'equal'.
+ Can be used to make plot fill whole plot region, even if the
+ plot region doesn't match the aspect ratio of the map region.
* added date2index function, updated netcdftime to 0.7.1.
* added maskoceans function.
* update pupynere to version 1.0.8 (supports writing large files).
