Release notes

🚀 v3.0.0 — Initial Release (Node.js Rewrite, ubuntu-slim Compatible)

This is the initial release of action-slack-notify, a fully Node.js–based reimplementation of the original [rtCamp/action-slack-notify](https://github.com/rtCamp/action-slack-notify).

The original rtCamp action runs a Go binary inside a Docker container. However, newer GitHub-hosted runners such as ubuntu-slim do not support Docker because they execute workflows in a containerized, restricted environment. As a result, the upstream action cannot be used on these lightweight runners.

This project solves that problem by providing a Docker-free JavaScript action that runs natively in the Node 20 runtime, making it compatible with ubuntu-slim and other environments where Docker is unavailable.

✨ Highlights

• Rewritten entirely in Node.js — no Docker required
• Works on ubuntu-slim, container-restricted runners, and self-hosted runners without Docker
• Drop-in replacement for the most common usage of the original rtCamp action
• Faster startup and lower overhead compared to container-based actions
• Easier to extend and maintain as a pure JavaScript action
