At risk
At risk: no human commits in a year.
Why
- No human commits since August 2020. (source 1, source 2, source 3, source 4)
- One person wrote 71% of human commits in the last year, and no human has committed in the last 90 days. (source 1, source 2)
What would change this
- A release or merged commit from a maintainer.
- A human commit in the last 90 days, or a second person taking a large share of commits.

Bursts
- Jul 6, 2015 to Aug 2, 2015: about 1.5k more stars than usual, peak 313 in one day, a spike that tapers off. Outside explanation: a jump in forks, a jump in issues and pull requests.
