Warning about conversion from older project file

[paddy-exe]

Godot version: v4.0.dev.custom_build [1d6f8ad83]

Also not sure if that's related but I also get the following errors when opening the project:

Failed loading resource: res://example.gdextension. Make sure resources have been imported by opening the project in the editor at least once.

  res://main.gd:9 - Parse Error: "Example" was not found in the current scope.

Also not sure if that's related but I also get the following errors when opening the project:

I believe the GDExtension format has changed since it was first introduced, so you need to compile the extension again.

The project.godot format upgrade is required to allow for random subresource IDs. The project linked in the blog post probably won't be updated (as it doesn't use version control). Instead, a demo project can be added to this repository or in the godot-demo-projects repository.
