ESRI has announced that ArcGIS 9.1 is now available. ArcGIS 9.1 is a full release of ArcGIS Desktop (ArcReader, ArcView, ArcEditor, and ArcInfo), ArcGIS Engine, ArcGIS Server, ArcIMS, and ArcSDE. In addition, it is the main vehicle for the release of Network Analyst on the ArcGIS platform.

Key features of ArcGIS 9.1 are that it has improved quality, stability, and performance. ArcGIS 9.1 includes user-requested quality improvements and enhancements across all products and adds support for large datasets.

This new extension to the ArcGIS platform provides network-based spatial analysis including routing, travel directions, closest facility, and service area analysis in addition to multimodal network support. The Network Analyst functionality is available for ArcGIS Desktop, ArcGIS Engine, and ArcGIS Server.
