Ah - sorry - I saw your original mention of `bugfix-2.2.x-mfs` and forgot we’re actually using `bugfix-2.1.x`.

All built firmware is against `bugfix-2.1.x`.

I’ll continue this on at the following thread - instead of having two parallel ones for the same info:

> [@Configuration file downlaod button](https://marlin.crc.id.au/forum/t/configuration-file-downlaod-button/1530):
>
> I suggest adding a Configuration.h and Configuration\_adv.h download button so people who want to edit something that isn’t in the Firmware Builder can do it by themselves.
