airbrussh configuration of command_output not working

[avonderluft]

Steps to reproduce

Using default airbrussh format in cap 3.8

In my deploy.rb I'm setting command_output to false, but everything still shows on the console.

set :log_level, :info
set :format_options, command_output: false, log_file: "deploy_logs/deploying.log"

Expected behavior

no output (or minimal) to console

Actual behavior

Full output to console, no matter what is set as command_output false or :stderr

System configuration
