version 0.99.3 (not yet released)
+ * if upper right/lower left corners nor width/height given for
+ azimuthal equidistant ('aeqd') the whole world is drawn in
+ a circle (only works for perfect spheres, not ellipsoids).
* have setup.py check for already installed pyshapelib (just
like it does for httplib2 and pydap).
* Basemap will now look for it's data in BASEMAPDATA.
