# Changelog

This file tracks user-visible changes in Red Bear OS.

When a commit changes the visible system surface, supported hardware, build flow, shipped configs,
or major documentation status, add a short note here and keep the README "What's New" section in
sync with the newest highlights.

## 2026-04-14

- Added a canonical GitHub-visible Red Bear OS implementation plan under `docs/` and linked it from the main README and docs index.
- Added a user-visible GitHub-facing "What's New" section to the root README and linked it to this running changelog.
- Added a new `redbear-kde` configuration and documented current KDE bring-up status as in-progress rather than not started.
- Refreshed top-level and docs status notes so historical roadmap documents no longer read as the current repo state.
- Expanded shipped Red Bear system tooling and config coverage around runtime diagnostics, native hardware listing, and Redox-native networking flows.
- Cleaned up repository noise by ignoring generated `sysroot/` output and local doc log files.
