Project maintenance and future?

[pmlk]

This project seems to be fairly popular and I was unable to find a better alternative. However, seeing that the last commit in this project was almost two years ago, issues stay unanswered, PRs not reviewed and not merged, I'd consider this project no longer being actively maintained. For that reason I am reluctant to use it, and I'm sure others are as well.

What can we as a community do to help maintain this project?
