Latest release notes

We are pleased to announce the latest update to Altitude, released on April 23, 2026.

Portal 2.0 2.4.0

OD Corridor Zone Access: Updated the corridor access check to allow origin and destination zones that touch — but do not overlap — to be used in corridor analysis. This expands the range of valid zone configurations supported in corridor analyses.
Map Zone Visibility: Adjusted default opacity values for zones on the map so that hovered and selected zones remain visually distinct from the default state.
Custom Zones Data: Added an isPurchased attribute to the custom zones data, making it easier to identify which zones belong to a purchased dataset.
Internal: Miscellaneous UI fixes.
