Looking at Pharo 4.0 First, I'm a little confused by the Configuration Browser - did this replace Monticello?. I'm not clear on the difference between a package and configuration and also the "Load Stable" vs "Load Configuration". Is Load Configuration the bleeding edge or something? I guess I could use a primer on the new modern way of managing code packages. I have a project to do that will involve a raspberry pi 2, a data feed from an arduino managing sensors, mapping/navigation, and a touch screen. In my googling I have spotted some articles on running Pharo on raspberry pi, and open street map with roassal2. I'm basically building an appliance here but would love to develop on my mac and deploy to the raspberry pi 2 as full screen. I looked at the release notes for raspbian OS and it seems a package 'squeak-vm' was updated in 2013 for it. Not sure about cairo for roassal2? Any pointers? I think this could be a really cool use case for Pharo. Thanks -Todd Blanchard
