Summary
We've got some major quality-of-life changes in this version. The Creator Companion no longer needs to open Unity in order to create new projects or migrate existing ones. This greatly speeds up the process. Once the project is created or migrated, the VCC will give you an easy "Open Project" button to open up your project in the right version of Unity, which may take a while since Asset Importing, etc is no longer handled as part of the initial process.
There's also a bevy of Canny bugs fixed below, thanks for reporting them!
