Bumpy – versioning/changelog tool, fixed 120 open changesets issues
Meet bumpy - your new favourite open-source versioning, release, and changelog tool. Especially useful in monorepos with many related packages, but also great to use in simpler setups. This is a modern successor to the popular changesets tool, used by many open source projects. While changesets is great, and I love the file-based bump+changelog workflow, the project has hundreds of open issues, many of which have been open for multiple years. Bumpy fixes most of the important ones (over 120+ by my last count), and adds some new features as well. It also greatly simplifies things, so it…
What it does
In the maker’s words, at launch
Meet bumpy - your new favourite open-source versioning, release, and changelog tool. Especially useful in monorepos with many related packages, but also great to use in simpler setups. This is a modern successor to the popular changesets tool, used by many open source projects. While changesets is great, and I love the file-based bump+changelog workflow, the project has hundreds of open issues, many of which have been open for multiple years. Bumpy fixes most of the important ones (over 120+ by my last count), and adds some new features as well. It also greatly simplifies things, so it should be easier to evolve as folks start pushing its limits. Some highlights: - changesets is built as a monorepo with 20 subpackages, this is a much simpler monolith - changesets requires you install a github app, use a github action, an npm module, and another for changelog formatting (this is a single install) - much more flexible include/exclude logic, instead of assuming behaviour is the same for all private packages - allows custom publishing commands, does not assume/force npm publishing - more sane peer dependency bumping logic - built in formatters, and easier to write custom ones - non-interactive version of add command (useful for agents) - it's infested with delightful frogs - lots of other small quality of life improvements What's missing: - no prerelease workflows yet (changesets users say this part of it is very confusing, so want to get it right) - I want to allow multiple publish targets per package - Add plugin system to define common publishing targets (e.g., VSCode extension marketplace) Yes it was coded using AI, but carefully. There is a comprehensive test suite. We are using it actively to release varlock along with 25+ related libs and plugins. Run `bunx @varlock/bumpy init` to get started - if you are using changesets, it will help you migrate automatically.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
