Cranko is a release automation tool that enables a novel workflow that I call just-in-time versioning. The latest release, 0.4.0, adds support for repos containing Python projects, to go along with existing support for Rust and NPM projects.
I created Cranko because, after many years of being dissatisfied with my release workflows, I think I finally came up with a sound approach. I've found it hard to convey in writing just why I think it's such a big deal, so: here's a video!
(You might notice from the release notes that Python support was added in the 0.3 series, not 0.4, but Python support is the most interesting new feature since I last posted about this project here.)
