backlog_timestamp must be used instead.
The default behavior is unchanged and can explicitly used with:
backlog_timestamp = "time";
The "none" value can be used with the backlog_timestamp parameter in
order to use the same behavior that the "no" value of the deprecated
parameter backlog_no_timestamp provided.
The date can now be displayed (in addition to the time) while backlogging:
backlog_timestamp = "datetime";
In "basic" mode, normally un trusted certificates get to be trusted if they are
manually trusted by user. This provides an SSH like private key auth mechanism.
Expired certificates were considered invalid in this mode which does not make
much sense.
