There’s an updated (October 2021) Power Platform Licensing Guide.
The main update is for the changes to Power Apps Per App licensing which is now just that – a single licence allows access to one app or one portal rather than the previous two apps and one portal. Entitlements for the new Intelligent Order Management are also added, and notice of end of support for WinAutomation at 31 December, 2021.
