Installed iso for 142 Build: master/9ff65bfa. Restored backup config from 141. DNS server list from 141 did not import into 142 but apart from that everything I use seems to be working normally.
When I had went from 139 to 141 the backup from 139 broke DNS every time and had to manually type in all my configuration into fresh 141 install. Not fun but allowed for a little clean up of my settings.
