I installed the v4.0.0-beta.1 release, but the "About" page shows the version number as 3.4.0.0

When the "Check For Update" button is clicked it states that a new update is available. This is despite the downloaded installer being v4.0.0-beta.1

I'm pretty sure this is the v4.0.0-beta.1 release as:
-it needed .NET 5.0
-it has the features added in that release (Group Packages by publisher, Download with IDM, etc...)
