The Supported Versions has been updated to reflect MS name change choice:
VSTS -> Azure DevOps.
But now it's even more confusing since Azure DevOps (cloud) is different to Azure DevOps Server (on-prem).
Given the REST API take a while to trickle down to the on-prem, it's possible the Supported capabilities differ between the two (assuming there are more tfs-plugin updates to come).
"Azure DevOps (cloud)" and "Azure DevOps Server (on-prem)" should be shown separately.
