For a long time we released every 4 to 6 weeks. We now release every week from a single GitHub Actions workflow. We built it using open-source tools and open-weights models and kept a human in the loop at the one place where judgment matters. Nothing in this post requires a vendor contract, a closed model, or infrastructure you can't run yourself. That was a design goal from the start since we wanted a workflow other maintainers could pick up and adapt.

By the end of this post, you'll have everything you need to build your own.

Writing good notes for a new version was the heavy part, aggregating tens of PRs on different topics. Nothing technically hard but a few hours of focused attention. Add the announcements on top and a minor release was easily a half-day of work spread over several days.

So we decided to streamline the whole thing. Looking at that list, the work splits in two.

Some steps are purely mechanical and can be automated: bumping the version, committing, tagging, pushing, opening downstream test branches, opening the post-release PR. Nobody needs to think about those. They just have to happen in the right order, every time, which is what a CI workflow is good at.

The rest is different. Writing release notes, deciding what to highlight, phrasing an announcement for a human audience: that's brain work. It's the kind of judgment that kept the release manual for years. This is where AI comes in, turning a blank page into a solid first draft in seconds.
