version 1.1.7

The NTPsec Project is pleased to announce the tagging of version 1.1.7

As aways, the most accurate record of changes is in the NEWS file, the git log, and the git history.

The numeric literal argument of the 'time1' fudge option on a clock can now have one or more letter suffixes that compensate for era rollover in a GPS device. Each "g" adds the number of seconds in a 1024-week (10-bit) GPS era. Each "G" adds the number of seconds in a 8192-week (13-bit) GPS era.

The neoclock4x driver has been removed, due to the hardware and the vendor having utterly vanished from the face of the earth.

The NTS ALPN negotiation sequence has been modified for improved interoperability with other NTS implementations.

NTS key rotation now happens every 24 hours. It used to rotate every hour to enable testing of recovery from stale cookies.
