CHANGELOG.md

@@ -5,6 +5,125 @@ 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).
 
+## [0.23.0] - 2026-05-22
+### Added
+- **Crash-logger trigger modes (M9 / D6)** via `systemd --user`, no root: **manual**,
+  **always-on** (a background service records continuously), and **game-launch** (auto-records
+  while a Steam game runs). Set it from **Settings → Recording trigger** or
+  `rigdoctor service mode <manual|always-on|game-launch>`; `rigdoctor service status` shows it.
+  `core/service.py` writes/enables the user units.
+- **Zero-config game-launch watcher** (`core/watcher.py`, `rigdoctor watch`) — polls Steam's
+  RunningAppID and brackets a focused capture around the running game (the D12 fallback for users
+  who don't add the `wrap` launch option; the wrapper stays the precise primary path).
+
+## [0.22.0] - 2026-05-22
+### Added
+- **M6 breadth.** Environment checks now also report **GPU PowerMizer** mode (NVIDIA, X — flags
+  Adaptive/Auto and suggests Prefer-Max-Performance), the **Wine** version, and the **Steam
+  client** version.
+- **Non-Steam launchers.** Lutris (its SQLite library) and Heroic (Epic + GOG JSON stores) are
+  detected (`core/launchers.py`) and listed on the Games page and `rigdoctor games`, tagged by
+  launcher. You can Run Diagnostic on them too (records while you play; auto-launch stays
+  Steam-only).
+### Notes
+- The zero-config game watcher (D12 fallback) is deferred to the M9 trigger-mode work, where the
+  service integration lives.
+
+## [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
+  **memory used/total**, a **status line** (Normal / Hot / GPU not responding), and is led by a
+  **Run Diagnostic** submenu (pick a detected game → the guided session), plus **Open dashboard**,
+  **Start/Stop recording**, **Snapshot (copy)**, and **Quit**. It reuses the dashboard's sample
+  stream (no extra sampling). With a tray present, **closing the window hides to the tray** (Quit
+  exits); `rigdoctor-gui --tray` starts hidden for autostart. Needs a tray host — on GNOME the
+  AppIndicator extension; degrades to a no-op if none is available. Completes the Desktop UI bundle.
+- **GUI smoke tests**: construct `MainWindow` headless and exercise the tray, so a startup crash
+  fails the build (closes the gap that let the 0.18.0 import regression ship).
+
+## [0.18.2] - 2026-05-22
+### Fixed
+- **GUI wouldn't start** (0.18.0 regression): the recording indicator used a wrong relative
+  import (`from .core` → `rigdoctor.gui.core`, which doesn't exist), crashing `MainWindow` on
+  launch. Corrected to `from ..core`.
+
+## [0.18.1] - 2026-05-22
+### Changed
+- Recording badge: dropped the sample count (not useful at a glance) — it now shows just
+  **● Recording** + the game, plus a **⚠ GPU-lost** line if one is detected.
+
+## [0.18.0] - 2026-05-22
+### Added
+- **Global recording indicator.** While a capture is running, the sidebar shows a red
+  **● Recording** badge on every page — with the **game** being captured and the live sample
+  count (and a GPU-lost flag if seen). It polls the recorder, so it reflects captures started
+  any way: manual `record`, a guided diagnostic, or the Steam launch wrapper.
+
+## [0.17.0] - 2026-05-22
+### Added
+- **Inventory page is back in the GUI** (it was removed in 0.7.2 in favor of the CLI). Sidebar
+  **Inventory** → System / CPU / Firmware / Memory / GPU / Storage / Display as cards, with
+  **Copy Markdown** and **Save…** for pasting into forum/bug reports, and **Refresh**. Root-only
+  details (motherboard/BIOS/RAM modules via dmidecode) fill in after the launch password prompt.
+  Backed by the existing M5 `core/inventory.py` — the CLI `rigdoctor inventory` is unchanged.
+
+## [0.16.0] - 2026-05-22
+### Added
+- **Automatic crash-capture via a Steam launch wrapper (M6/D12).** Set `rigdoctor wrap
+  %command%` as a game's Steam launch option (or in Lutris/Heroic's wrapper field) and RigDoctor
+  starts a focused, game-tagged capture when the game launches and stops it cleanly on exit — no
+  manual Run Diagnostic / Finish. A hard freeze leaves the capture unterminated, so it's flagged
+  as a crash next launch. The wrapper resolves the game name from Steam's `SteamAppId`, doesn't
+  disturb an existing capture, and returns the game's exit code. (`core/wrap.py`, `rigdoctor wrap`.)
+- GUI **Auto-capture…** helper on the Games page: shows the exact launch-option line (absolute
+  path, copy button) and how to set it in Steam.
+- Auto-capture preserves an unanalyzed crash (`diagnostic-crash.jsonl`) before starting a new
+  capture, so relaunching the game can't wipe a crash report you haven't seen yet.
+### Fixed
+- `docs/MODULES.md` status column was stale — M1, M3, M4, M5, M8, M10, and M13 are done and now
+  marked ✅ (only M2 and M11 remain not-started; M6/M9/M12 in progress).
+
+## [0.15.0] - 2026-05-22
+### Added
+- **Hard-crash detection & recovery for the guided diagnostic.** If a focused capture ends
+  without a clean stop (the recorder never wrote `session-stop` and isn't running), RigDoctor
+  treats it as a likely hard freeze. On launch the **Games** page shows a warning banner —
+  *"Your last diagnostic for <game> ended unexpectedly…"* — with **Analyze crash** / **Dismiss**.
+- **Deeper crash analysis.** *Analyze crash* combines the captured window (final readings before
+  the freeze + any GPU-lost event) with a focused scan of the **previous (crashed) boot's kernel
+  log** (`journalctl -k -b -1`: Xid/panic/OOM/MCE/AER/thermal) plus SMART/driver/persistence/
+  live-temp checks — the full "what happened" picture. `core/diagnostic.py` gains
+  `pending_crash()` / `analyze_crash()`; `health.check_previous_boot()` +
+  `run_health_checks(include_journal=False)` back it.
+
+## [0.14.0] - 2026-05-22
+### Changed
+- **Dashboard headline tiles are now history trend graphs** instead of single-value gauges —
+  GPU temp, GPU load, CPU temp, and memory each plot their recent history (with the current
+  value, window min/max, and a dashed warning-threshold line), so you can see changes over time
+  rather than only the instantaneous reading. New `HistoryGraph` widget (QPainter, no new deps).
+
 ## [0.13.0] - 2026-05-22
 ### Added
 - **Run Diagnostic now explains itself and can launch the game.** Clicking Run Diagnostic shows
