I have been using master binaries to test stuff and some of the latest master patch is not there. So, after investigating a bit, I think, the latest binaries are not being released for fd.io.master.ubuntu.trusty.main . The last release I see was on Fri May 19 13:02:45 UTC 2017 where as for fd.io.master.ubuntu.xenial.main the binary released is on Fri Jun 02 15:07:35 UTC 2017.

Is there any particular reason for that?
