DEPRECATED Action signature. Must be `cli.ActionFunc`. This is an error in the application. Please contact the distributor of this application if this is not you. See https://github.com/urfave/cli/blob/master/CHANGELOG.md#deprecated-cli-app-action-signature
Thanks for letting me know about this, I've been happily running a build that was compiled a while ago and didn't have this warning. The fix is pushed and builds are building, I'll push a new release shortly.
I get this warning on most commands.
Everything still seems to work for now.
