One of the results from our development meeting on September 14th was that I'd organize a testing matrix for features to be tested in VyOS 1.2 nightly builds.
Testing matrix is here: https://docs.google.com/spreadsheets/d/19jT6_erlS2bKGXJaAWQU-LIrMiWYv2Hok1ZqWK1dC3k/edit#gid=0
If you want to test a feature or submit feedback on a nightly build, please comment here and I'll grant you write access to the spreadsheet.
If you've discovered a bug in a nightly build, please raise a case as well.
