=============
This minor release:
- Changes the directions layer widget to add the `start`, `end` and `waypoints`
traitlets. This deprecates the `data` traitlet, scheduled for removal in 0.9.0.
(PR 236).
- The directions layer now reacts to changes in start, end and waypoints by
re-calculating the route (PR 239)
- The directions layer now supports styling the route (PR 247)
- Errors in the direction layer are now shown in the error box, rather than as
an uncatchable exception (PR 242)
- Errors authenticating result in an error message that replaces the map,
rather than the cryptic 'Oops, something went wrong' default that Google Maps
provides (PR 240)
- Adds style to error box (PR 243)
- Removes the deprecated `data` traitlet from the Heatmap and WeightedHeatmap
widgets. See PR 249 for a migration pathway. (PR 249)
- Introduces the Opacity traitlet for encoding stroke and fill opacities (PR 248)
