I released v0.2 of Tunnel Boring Machine for managing SSH tunnels. The core of this release is a significant improvement to the configuration file for my needs and the needs of the people I'm currently working with, although you can read through the GitHub issues if you want to know more.

I feel like the configuration file format is also stabilizing, so I've documented it reasonably thoroughly. There isn't that much left on my planned scope for v0.3, so I'll probably get that out sometime in the next month or so, although I do have some other things on my plate that will have to get done first.
