We’re introducing calendar-based versioning for our REST API, so we can keep evolving our API, whilst still giving integrators a smooth migration path and plenty of time to update their integrations.
We’ve been rendering GeoJSON files
for a while now, but now it’s even easier to preview them if you edit them in the
web view. Simply click the “Preview” button while editing to view a live preview of
the file as you’ve edited it. If you run into any issues, check out the
map help documentation.
