+## [0.36.0] - 2026-05-22
+### Fixed
+- **`.deb` now installs all dependencies automatically — no manual tool install.** The previous
+  `Recommends: python3-pyside6` named a package that doesn't exist on Debian/Ubuntu (PySide6 is
+  split per module), so apt silently skipped it and the GUI wouldn't start. Now it Recommends the
+  actual modules the GUI imports — `python3-pyside6.qt{widgets,gui,websockets,svg}` + `python3-pyte`.
+### Changed
+- **`apt install rigdoctor` sets up the whole toolset.** The `.deb` also Recommends the optional
+  diagnostic/gaming tools (smartmontools, lm-sensors, dmidecode, pciutils, libnotify-bin,
+  libsecret-tools, gamemode, mangohud) so they install by default — users never hand-install
+  tools. `cpupower` is a Suggests (kernel-tied); `--no-install-recommends` still gives CLI-only.

 ## [0.35.0] - 2026-05-22
 ### Added
 - **`.deb` package (M9 / D8)** — `packaging/make_deb.py` builds a `rigdoctor_<version>_all.deb`
