This blog post provides the latest updates regarding deprecated features in ArcGIS 10.4 and in the recent release of ArcGIS 10.4.1.
With each release, the platforms and functionality supported in the ArcGIS platform are assessed and adjusted based on customer needs and technology trends. The purpose of the Deprecated Features for ArcGIS document is to provide as much advanced notice as possible regarding these changes.
