Version v0.14.0 "Roland"

What's Changed

• Herd now has more generous default timeouts and adapts them based on the specified parallelism
• Connections are closed immediately after running a command, making herd much faster in environments where having thousands of open connections simultaneously is a problem
• Herd now makes multiple connections to your SSH agent, massively speeding up herd when run remotely with a forwarded agent.
• Hosts that exit with non-zero exitstatus and hosts where an error occurred now appear differently in the output. A side-effect is that all colors can now be customized.
• It is now possible to use host lists and results from previous commands as input for commands, making it easy to e.g. re-run commands or select hosts on which a command previously failed.
• Herd can now connect succesfully to hosts where 2fa is used but bypassed for the host herd is connecting from
• openssh configuration is now parsed with a real parser
• When redirecting herd's output, log and progress messages appear on stderr to avoid polluting the redirected output

Breaking change (cli):

• The known_hosts provider is no longer loaded by default, due to its tendency to collect outdated information

Breaking changes (API)

• The signature of the NewExecutor and NewSimpleUI functions has changed
• The UI interface no longer has a Write method
