Version 2.26.0 of the developer tools for the Slack automations platform is here!

    We've updated the formatting for section text and trace prints for the slack collaborator add, slack collaborator list, and slack collaborator remove commands.

Version 2.24.0 of the developer tools for the Slack automations platform has landed!
