ArcGIS Pro 2.3 just became available today. Check out what’s new here.
Quite a few customer requests were added to this release. To view what they are, ESRI has made a video of each request.
The system requirements for 2.3 can be found here. ArcGIS Pro will not be supported on Windows 7 after January 2020.
And if you have been running ArcGIS Pro on a Mac using Parallels or VMware Fusion, at 2.3 you will not be able to do that anymore. Instead you must use Boot Camp. Read more about that here.
