Yes, the project is still alive and well! It also powers our very alive commercial service, Write.as, which has most of my attention. The open source project is just moving at a one-maintainer pace because it only has one maintainer :)
There will definitely be future releases, especially once we get through a roadblock with the tool we use to cross-compile WriteFreely [0]. Otherwise, anyone who wants to see the project move faster is more than welcome to contribute, especially with tasks like code review, to help clear out those PRs [1].
