## Breaking CLI Change
* The `ziti edge enroll` and `ziti-tunnel enroll` subcommands no longer require a --jwt argument. Instead the JWT can be supplied as the first argument. So `ziti edge enroll --jwt /path/to/my.jwt` would become `ziti edge enroll /path/to/my.jwt`. For now the --jwt flag is still accepted as well.
