Some parameter names were changed. This could affect any custom scripts you have.

1. Create a copy of PlanetCNC installation folder (normally this includes all your profiles)
2. Extract .exe and two .dll files from BETA .zip and replace existing files
3. Now you have both versions installed simultaneously. Firmware is the same so you can use which one you want.

I recommend that you do this because eventually BETA will become current.
Everything is ready except some parameters need to be documented:

And I'm doing minor tweaks like the one you requested.
