+## 0.7.0 - 2026-09-24
+
+The SteamOS theme comes from CachyOS's `cachyos-vapor` package, applied with
+Vapor's own desktop layout, and gains the SteamOS desktop extras. The Steam
+Machine LED driver works on every installed kernel and survives kernel updates.
+
+- `978f5a1` **feat: SteamOS theme from cachyos-vapor with its desktop layout, plus SteamOS desktop extras**
+  - Installs `cachyos-vapor` instead of extracting Valve's `steamdeck-kde-presets`
+    into `~/.local/share`; removes it on disable if the wizard installed it.
+  - Applies the Vapor global theme with "Desktop and window layout": Steam Deck
+    wallpaper, SteamOS panel and launcher icon. Layout files are backed up and
+    restored; every key from Vapor's defaults goes through the undo journal.
+  - Restores the real previous color scheme on disable (CachyOS's BreezeDark
+    colors have no scheme name), instead of falling back to light Breeze.
+  - Registers Vapor as the dark theme, so Plasma's Dark Mode toggle shows on.
+  - Drops the extra SteamOS desktop defaults (GTK, Konsole, gsettings, panel tweaks).
+  - New SteamOS desktop extras, downloaded from Valve's newest
+    `steamdeck-kde-presets` (checksum verified) into `/usr/local`: Add to Steam,
+    Nested Desktop, the SteamOS Return to Gaming Mode icon, the Steam Keyboard
+    window rule and an empty KWallet (only when there is no wallet yet).
+  - Single user mode's launcher settings are re-applied after the layout reset.
+- `7802d90` **fix: LED driver for every kernel, kernel headers at boot, console power button, kernel overview**
+  - DKMS override (`/etc/dkms/leds-valve-dkms.conf`) so the LED driver builds
+    for every installed kernel (the LTS kernel failed) and on kernel updates.
+  - `ensure-kernel-headers.service` installs missing kernel headers at boot, so
+    a newly added kernel gets the LED driver too.
+  - Power button sleeps and no automatic suspend on mains power (Steam Machine).
+  - Menu shows every kernel with its headers, Steam controller driver and LED
+    driver, plus whether the LEDs are loaded.
+  - The selected menu row is highlighted in full.

+Installs CachyOS's `cachyos-vapor` package (the SteamOS Vapor theme the
+CachyOS handheld edition uses) from the CachyOS repository and switches your
+desktop to its Vapor global theme, including its desktop and window layout
+(like ticking "Desktop and window layout" in System Settings): Vapor colors
+and Plasma style, the SteamOS panel and launcher icon, and the Steam Deck
+wallpaper. Run it from the Plasma desktop: applying the layout needs a
+running Plasma session.
 
-- the Vapor global theme, color scheme, Plasma style, wallpapers and icons;
-- the Vapor GTK theme, Konsole profile and user avatars;
-- Valve's SteamOS desktop defaults, merged into your own config: Noto Sans
-  fonts, no Xwayland input-permission prompt for Steam Input, the window
-  rule that keeps the Steam keyboard on top and out of the taskbar, no
-  welcome screen, light file indexing;
-- the SteamOS panel: solid (not floating), full width, 44 px high, tray icons
-  scaled to fit, date below the time, and the SteamOS launcher icon;
-- dark mode for GTK, libadwaita and portal-aware apps (Firefox, Flatpaks).
+It also adds the SteamOS desktop extras that `cachyos-vapor` doesn't ship,
+taken from the newest `steamdeck-kde-presets` on Valve's SteamOS mirror

-effect at the next desktop login.
+- **Add to Steam** in the right-click menu of apps, AppImages and `.exe`
+  files, and in the launcher: adds them to Steam as non-Steam games;
+- **Nested Desktop**: add it to Steam from the launcher, then start it in
+  gaming mode for a Plasma desktop inside gaming mode;
+- the SteamOS **Return to Gaming Mode** icon (Steam logo with a return arrow);
+- a window rule that keeps the **Steam keyboard** above other windows;
+- an empty, password-less **KWallet**, only if you don't have a wallet yet,
+  so nothing asks for a wallet password after autologin.
 
-**Package version.** The script always takes the newest
-`steamdeck-kde-presets` from the highest-numbered SteamOS release repository
-on the mirror (`jupiter-3.9`, `jupiter-3.10`, ...). That repository's pacman
-database gives the exact file name and SHA-256 checksum, which is verified
-after downloading. If the lookup fails, it falls back to the known-good
-3.9.4 (see `install_vapor_theme()` in `lib/vapor-theme.sh`). To check the
-current version yourself:
-
-```bash
-m=https://steamdeck-packages.steamos.cloud/archlinux-mirror
-r=$(curl -fsL $m/ | grep -oE 'jupiter-[0-9]+\.[0-9]+/' | tr -d / | sort -V | tail -n 1)
-curl -fsL $m/$r/os/x86_64/$r.db | bsdtar -tf - | grep -o '^steamdeck-kde-presets-[^/]*' | sort -u
-```
