The record

Purpose: Bumpy is a package versioning, release, and changelog generation tool built for monorepos and also usable in simpler projects.
Workflow: It uses Markdown bump files to declare package bump levels and changelog descriptions, which can be reviewed in pull requests.
Release automation: Two GitHub Actions workflows can check pull requests, maintain a release pull request, and publish packages when that release pull request is merged.
Dependency propagation: Configurable rules control how version bumps cascade through the package dependency graph.
Publishing targets: Per-package custom publish commands can target destinations such as VSCode extensions, Docker images, JSR, and private registries.
Release options: It supports aggregated GitHub releases, branch-based prerelease channels, commit-based bump-file generation, and pluggable changelog formatters.
Security-related design: The repository says Bumpy uses OIDC and staged publishing, and does not require a separate GitHub action or app.
AI tooling: Bumpy includes an agent skill for creating and updating bump files and lists compatibility with Claude Code, Cursor, OpenCode, Codex, and other agents.
Installation: The repository documents installing @varlock/bumpy as a development dependency with Bun, npm, pnpm, or Yarn.
License: The project is released under the MIT license, which grants permission to use, copy, modify, distribute, and sell copies subject to the license conditions.
Known roadmap limits: The roadmap lists a standalone binary and better support for non-JavaScript packages as future work.
Maker: DMNO Inc. identifies Bumpy as one of its products; its site names Theo Ephraim and Phil Miller as founders.
