Restart UP Studio after every change in Material Manager?

Hello, i have read that i need to close the Material Profile Manager and need to restart UP Studio when i create a new filament profile. Do i need too, while im tweeking an existing profile or will the settings than be saved and updated automatically?

For more recent version of the software, there is no need to restart UP Studio to reload the parameters.

Given the negative experiences with some of the upgrades it could probably be a good idea to specify which version no longer needs a restart to avoid otherwise unnecessary updates?
