release-1.0.3

This release, unfortunately, drops binaries for different OS and architectures. This is necessary because the previous binaries just didn't work - each would complain about the lack of CGO being present for the SQLite3 library.

In terms of functional changes we now only regard nodes as orphaned if they've not been seen for three and a half days, rather than 24 hours. It is also possible to prune orphaned hosts, via "puppet-summary prune -orphaned"
