version 0.2
==============
- Test items: each item type now declares its accepted parameters
  (``PARAMS = ParamSet(...)``). Typos in a ``.tum`` are surfaced as a
  WARN listing the accepted names instead of being silently ignored;
  missing required parameters error out at load time with the source
  ``.tum`` file as context. No change to valid existing tests.
- Editor support: testium now ships a language server. ``testium lsp``
  gives ``.tum`` files item-type completion, hover documentation and an
  outline view in any LSP-capable editor (a VSCode / VSCodium client is
  provided separately). ``testium schema`` dumps the item/parameter
  schema as JSON. The server works from every channel — bundled in the
  binary / Flatpak / AppImage, and pulled by ``pip install testium[lsp]``
  for wheel installs.
- build_all.sh: the four heavy channels now build in parallel (results
  reported as each finishes; Ctrl+C stops them cleanly). New ``--ram``
  option builds on a tmpfs (``/dev/shm``) and skips UPX for much faster
  packaging on USB-stick / SD-card storage.

version 0.1.3
==============
- Stop interrupts engaged blocking steps (console, py_func, lua_func,
  json_rpc, sleep) within ~200 ms instead of waiting for the step
  to finish.
- GUI Start / Stop / Pause flow simplified.
- lua_func: a function returning nil is no longer reported as a failure.
- ``-d python_bin=...`` and the GUI ``python_bin`` preference now reach
  the eval subprocess (used to be silently ignored). ``param.yaml`` can
  also override ``python_bin`` for py_func / cycle / post_exec.
- Validation suite: ``test/validation/run.sh`` (and ``run.bat``)
  runs the suite inside a dedicated venv in the system temp dir.
- build_all.sh: ``release_note.txt`` and the user manual copied into
  ``dist/``; warning if the file has no entry for the version being built.
- Flatpak: every GUI file/directory dialog (open test, save report, log
  path, default report/log dirs, python/lua interpreter pickers) now
  bypasses the XDG document portal — the v0.1.2 fix was only on the
  "open test" dialog.
- Flatpak: py_func / lua_func / run sub-instance now execute on the host
  via flatpak-spawn, lifting the previous glibc/ABI incompatibility that
  prevented user-configured host Python or Lua interpreters from being
  reached from the sandbox.
- Validation suite: single entry point with ``--mode source|wheel|
  pyinstaller|flatpak|appimage`` to validate any packaging channel
  against the same item set; reports are stamped per mode.
- GUI: the "Run tum" test item now uses the testium logo.

version 0.1.2
==============
- Flatpak: opening a test from the GUI now correctly finds its companion
  files (param.yaml, .py scripts, ...).

version 0.1.1
==============
- New install channels: Flatpak bundle and AppImage. The AppImage runs
  on any distribution (built inside a Debian container).
- About dialog: version is now correct in Flatpak and AppImage builds
  (used to display "unknown").
- GUI dialogs no longer hang on pure-Wayland sessions.
- Plot "last values" API: more tolerant timeout on loaded machines.
- run item: `testium_path` and `python_bin` parameters removed —
  sub-instances are launched in the same packaging mode as the parent.
- License: EUPL-1.2.
