+version 0.1.1
+==============
+- Packaging: Flatpak bundle (desktop entry, MIME, distributable .flatpak)
+  and AppImage (containerized build, runs on Arch / non-Debian hosts).
+- bins.py: host-only Python/Lua resolution from sandboxed bundles
+  (Flatpak / AppImage); fail fast at test load if the host interpreter
+  is missing.
+- run item: runtime-aware launcher (AppImage / Flatpak / PyInstaller /
+  source / wheel); drop testium_path / python_bin parameters.
+- dialog_env: auto-detect Wayland vs xcb from $DISPLAY / $WAYLAND_DISPLAY
+  instead of forcing xcb (was hanging dialogs on pure-Wayland sessions).
+- version: read TESTIUM_VERSION env in Flatpak/AppImage so the About
+  dialog stops reporting "unknown".
+- runtime_plot last_values: bump timeout 1s -> 5s and narrow the bare
+  except to queue.Empty.
+- py_func/__main__: robust sys.path init, diagnostic on import failure.
+- Subprocess stdio (py_func / lua_func) routed into the parent log.
+- README refocused on users (quick_start, tutorial); CONTRIBUTING filled.
+- Docs: CLAUDE.md Packaging section rewritten.
+- LICENSE file (EUPL-1.2) added.
