NEW CONTRIBUTOR LICENSE AGREEMENT I have set up a new CLA system based on https://cla-assistant.io/. The new CLA is based on a template from Nubank but is, to my eye, essentially the same as the old CLA. Essentially, it is confirming that you are authorized to grant the code changes to the Nubank organization. I have not used this tool before, and there doesn't appear to be a way to import prior data ... so, regrettably, you will need to re-sign the new CLA, but it's one time, easy, and should take only seconds.
I just ran through the process for a trivial PR and it was basically smooth.
It looks like I could import prior signers, but because the new CLA is slightly different (it references Nubank) I'd prefer if people did sign the new CLA instead.
