ArcGIS 10.7.1 works with the Redistricting Extension which is very useful. I've been told by customer service that it will not work with ArcGIS 10.8.1 or 10.8. I think this may be a simple software fix. Also, I would like to see some capabilities added that may be similar to Caliper's extension for ArcGIS (like statistical measures of district compactness, etc.). This should be simple as well. As we are moving into the season of redistricting for the next few years, this extension should be updated to work with the latest version of ArcGIS. Needless to say, not all discussions of redistricting can take place using ArcGIS Online.
