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.
More info can be found here. Release notes can be found here.
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.
