Cab3 Updates - Where to Find Future Updates?

@JamesR posted:

We know there will be updates to Cab3 to add and fix certain features. I am most interested in enabling assigning TR1 and TR2 to my Powermasters so I can control track voltage/run conventional locos. Instructions are included on the Power and Control website, but it doesn't work.  Dave said this was on his "to do" list in response to an earlier post about that issue.

Here is the question: Where would be the best place to look for updates to Cab3 and information on what has been updated/fixed?

Will iPhones/iPads automatically look for new versions of the Cab3 app as they do for other apps and tell us what has been changed/fixed? Should we look on the Power and Control website for references to changes/fixes? Some Lionel facebook page? - there are many.

For the App they should either update automatically or ask you to update it.  This is all done through their respective App stores.

I would think the P&C website would at some point list the fixes if Lionel wants to or if you go to the App store once it updates they usually put a list of what the version correct.
