 release tag (so the auto-updater, D18, can compare versions).
 
+## [0.42.0] - 2026-05-29
+### Added
+- **Detect hard freezes that log no Xid.** The kernel-log scanner caught Xid codes, OOM, panic,
+  MCE, PCIe AER, thermal events, and amdgpu resets — but a crash that logs *no* Xid slipped
+  through. It now flags the NVIDIA open-kernel-module **VA-space mapping fault** (`gpu_vaspace.c`
+  / `dmaAllocMapping` assertions, NVKMS GEM-allocation failures) — a driver-internal error that
+  can storm for minutes and end in a freeze without the GPU ever "falling off the bus" (distinct
+  from Xid 79). A new `check_nvidia_module()` notes when the open module (`nvidia-*-open`) is
+  loaded — the context behind these faults — and a new `ai_knowledge` entry lets the assistant
+  tell the no-Xid freeze apart from the Xid 79 hardware drop.
+- **Add games no launcher reports (e.g. SPT).** A user-authored custom-games list
+  (`core/customgames.py`) shows alongside Steam/Lutris/Heroic in `rigdoctor games` and the GUI
+  ("Add game…"), for standalone mod launchers (Single-Player Tarkov), itch.io downloads, or any
+  hand-installed game. Each entry can carry a launch command and a log directory:
+  `rigdoctor games add "SPT" --command .../tarkov.sh` (a sibling `logs/` is auto-detected),
+  `rigdoctor games play "SPT"` launches it under the crash-capture wrapper (tagged with the real
+  name, not the script's), and the diagnostic now tails the game's *own* logs — SPT's
+  server/launcher logs — alongside the kernel log so the analysis sees what the game logged
+  before the freeze.
