Release 0.18.4

What's New

• New ziti CLI command ziti ps set-log-level, allows you to set the application wide log level at
  runtime
• Allow invalid event types in controller config event subscriptions. Instead of failing to start,
  the controller will emit a warning. This allows us to use uniform configs across controllers which
  may not all support the same event types.
• Edge routers now have configurable timeouts when looking up API sessions and sessions

Edge Router: Configurable Session Lookup Times

An Edge SDK client will create and api session and session with the controller first, then attempt
to use those sessions at an edge router. The controller will push session information to routers as
quickly as it can, but clients may still connect to the edge router before the client can. We
previously would wait up to 5 seconds for session to arrive before declaring a session invalid, but
would not wait for api-sessions.

We can now wait for both api-sessions and sessions. Both timeouts are configurable. They are
configured in the router config file under listeners options.

• lookupApiSessionTimeout
  • How long to wait before timing out when looking up api-sessions after client connect. Default
    5 seconds.
• lookupSessionTimeout
  • How long to wait before timing out when looking up sessions after client dial/bind. Default 5
    seconds.

Example router config file stanza:

listeners:
  - binding: edge
    address: tls:0.0.0.0:6342
    options: 
      advertise: 127.0.0.1:6432
      lookupApiSessionTimeout: 5s
      lookupSessionTimeout: 5s
