Hello,
To clarify, the latest release did not introduce multisite support. Multisite support has been implemented since 2017. See the 2.2.3 release notes for multisite support, and the 2.4.0 release notes for network-active multisite support.
The latest patch 5.0.11 resolves an issue with installing the plugin on distinct sites in a network installation, as opposed to network-activating the plugin across all sites.
You bring up a valid point: I have put out too little information about this. I will write an in depth how-to guide on this topic, detailing all the different choices and trade-offs.
I will post the link here when it’s ready, hopefully later today.
with regards
