+# Changelog
+
+All notable changes, per version and per commit. Versions follow
+[Semantic Versioning](https://semver.org/) and were numbered from the start
+of the history.
+
+## 0.2.0 - 2026-09-24
+
+Watchable test runs and the lessons from testing cachyos-gamescope-boot 0.7.0
+(cachyos-vapor theme, LED driver on every kernel).
+
+- `b4114a1` **feat: Visible wizard runs, one-step VM reset and screenshots; skill updates**
+  - `scripts/vmreset.sh [--fremont]`: restore `ssh-ready`, boot, mount the repo,
+    set up the test autologin and wait for Plasma.
+  - `scripts/vmwatch.sh '<input>' [label]`: run the wizard in a visible Konsole
+    in the VM, so someone at the QEMU window can follow along.
+  - `scripts/vmshot.sh <out.png>`: screenshot via a user unit (spectacle
+    crashes when started straight from SSH).
+  - `scripts/vmstate.sh`: DKMS status per kernel, the DKMS override, the kernel
+    headers service, the dark look-and-feel, the wallpaper and the theme's
+    layout backup.
+  - `scripts/cmp.sh`: also compares `kcminputrc` and `ksplashrc`.
+  - Skill: VM directory outside the repo, the menu's first-run pre-ticks and
+    the conversion/single-user coupling, the repo mount lost on reboot,
+    re-applying the conversion resets the session to gamescope, the new
+    theme and LED checks in the test matrix, and the broken mirror workaround.
