ArcGIS Pro provides a nice GUI for updating python libraries used by the software. For folks like me this makes it so much easier to get started with the python features, since I don't have to worry about learning Conda. However, when I hear about a new version of the arcgis python library being available, when I go to the Python Package Manager, it is not shown as an option to update. I am curious why this flagship library from Esri is not available for update through this window when so many smaller ancillary libraries are available.
I do know that the Python API help has a page explaining how to do the update via the conda terminal: Install and set up | ArcGIS for Developers . However, the instructions don't look like they've been updated since 2.2. Also, it is a little clunky to go through these steps when Pro has a feature to make updates easier.
