This attempts to hide inter-keystroke timings by sending interactive
traffic at fixed intervals (default: every 20ms) when there is only a
small amount of data being sent. It also sends fake "chaff" keystrokes
for a random interval after the last real keystroke. These are
controlled by a new ssh_config ObscureKeystrokeTiming keyword/

This adds a ssh_config(5) "Tag" directive and corresponding
"Match tag" predicate that may be used to select blocks of
configuration similar to the pf.conf(5) keywords of the same
name.

This allows matching on the addresses of available network interfaces
and may be used to vary the effective client configuration based on
network location (e.g. to use a ProxyJump when not on a particular
network).

This option (default "no") controls whether the ~C escape is available.
Turning it off by default means we will soon be able to use a stricter
default pledge(2) in the client.

this also for IdentityFile in ssh_config.5, for documentation completeness.

ignored. If a host presents a host key beneath this limit then the connection
will be terminated (unfortunately there are no fallbacks in the protocol for
host authentication).

accurately reflects its effect. This matches a previous change to
PubkeyAcceptedAlgorithms. The previous names are retained as aliases. ok

PubkeyAcceptedAlgorithms. While the two were originally equivalent, this
actually specifies the signature algorithms that are accepted. Some key
types (eg RSA) can be used by multiple algorithms (eg ssh-rsa, rsa-sha2-512)
so the old name is becoming increasingly misleading. The old name is
retained as an alias. Prompted by bz#3253, help & ok djm@, man page help jmc@

The command accepts bunch of %-expansions, including details of the
connection and the offered server host key. Note that the command may
be invoked up to three times per connection (see the manpage for
details).
