So the ESRI Business Partner Conference and the Developer Summit is coming up and that means that ESRI will be showing the latest releases of their software. In preparation of the DevSummit, ESRI has published new features of ArcGIS 9.3.1. I’m interested to see the faster rendering and map optimization. One thing that did catch my eye:

Upgrading to ArcGIS 9.3.1 does not require uninstalling ArcGIS 9.3.

That should speed the upgrade times up from hours to minutes. Expect 9.1.1?9.3.1 second quarter (April, May, June) 2009.
