Yes own install on a Pi
Master or Stable, what ever the original install instructions said 
How can I check? is it in the .git? Stable I am guessing.
Would it not be possible for the admin page to interrogate this file and put the information there? Perhaps a separate version status page would be a good addition? Is is apin to have to go into each module folder to test to see if there is an update or not.
Is there not an upgrading page anywhere? Do I need to stop any of the processes?
There is a comment on the need to update the settings file. Is there any more detail anywhere?
Cheers
