Changes:
KML regionating has been optimized and per-layer security enhanced. Regionating is the process of automatically filtering what data is shown based on an attribute of that data (e.g. only showing large features when zoomed out). Currently regionating is only functional for KML output, but this may eventually change. Per-layer security allows for layers to be viewable based on certain security credentials.
