CHANGELOG.md

@@ -5,6 +5,27 @@ All notable changes to RigDoctor are recorded here. Format follows
 (`MAJOR.MINOR.PATCH`, pre-1.0). `__version__` and `pyproject.toml` must match the git
 release tag (so the auto-updater, D18, can compare versions).
 
+## [0.21.0] - 2026-05-22
+### Added
+- **Live monitor TUI (M2).** `rigdoctor monitor` is now a proper **curses** dashboard:
+  current / session-min / session-max per sensor, grouped by subsystem, with temperature and
+  utilization **color bands** (and GPU-lost flagged red). `q` quits, `r` resets the session
+  min/max. Falls back to a plain full-screen redraw on a non-TTY (`--plain` forces it). The
+  terminal face of the same live data the GUI dashboard graphs. Completes the Monitoring bundle.
+
+## [0.20.0] - 2026-05-22
+### Changed
+- **Reorganized navigation** into grouped sidebar sections — **Monitor** (Dashboard) ·
+  **Diagnose** (Games, Recordings, System Health, Tuning) · **System** (Inventory) · **App**
+  (Settings, Share) — so it's clear where to go.
+- **Renames for clarity:** *Health → System Health* (it's the overall 7-day system scan, not
+  per-game), *Environment → Tuning* (gaming tunables + fixes), *Logs → Recordings*,
+  *Setup → Settings*.
+- **Settings** absorbed **Notifications** (alerts) — app configuration (components/deps, alerts,
+  account access, uninstall) now lives in one page; Notifications is no longer a separate item.
+- **Recordings** is now a hub: pick which captured log to view (always-on capture, last
+  diagnostic, or a preserved crash), **Analyze crash** in place, alongside the recorder controls.
+
 ## [0.19.0] - 2026-05-22
 ### Added
 - **System-tray applet (M11, D13).** A tray icon whose menu shows live **CPU / GPU temp** and
