1) Is there a way to access previous versions of api doc? I am using python across AGOL and ArcGIS Enterprise over a long time and the versions' feature differences are important to investigate.
As at writing https://esri.github.io/arcgis-python-api/apidoc/html/ is version 1.6.2. There is no way to look at 1.6.1 or 1.5.0 for example, or I do not know how to. And going by release notes is quite hard.
2) Also, is there or can there be a compatibility table somewhere that describes the versions across the two platforms:
ArcGIS API for Python Version | AGOL | ArcGIS Enterprise
1.6.2 | Jul 19 |
1.6.1 | Mar 19 | 10.7.1 (Apr 19)
1.6.0 | Sep 18 | 10.7.0 (Dec 18)
1.5.3 | Mar 18 | 10.6.1 (Jul 18)
1.5.2 | Sep 17 | 10.6.0 (Apr 18)
^^^ I am guessing compatibility and dates in the above table, probably not accurate.
