New release of Entur GTFS feed
Entur plans to roll out an updated version of their GTFS feed on April 30th 2020.
This is a technical update aimed at improving the speed of the export process and reducing resource consumption on Entur's system.
The data scope and semantic is unchanged. Two minor changes in the data format are detailed below. They are not expected to impact data consumers.
1. Latitude/Longitude format

2. Point sequences in shape data.
According to the GTFS specification, point sequence values "must increase along the trip but do not need to be consecutive"
With the existing algorithm, this was achieved by incrementing a sequence number unique across the dataset.
The new algorithm resets the sequence for each shape object. Example:
