v4.0.6
======

v4.0.6 is a focused release built on Qt Creator 10.0.1 that adds a
command-line registration-key dialog, a suite of compile-time ``FORCE_*``
macros for locked-down factory builds, and a fix that routes auto-reconnect
through the standard user connect path. There are no breaking changes.

Highlights
----------

- **Registration key dialog** can now be requested at startup with the new
  ``-form_key_dialog`` command-line option.
- **Factory build macros** add a suite of compile-time ``FORCE_*`` overrides so
  locked-down builds run without command-line arguments.
- **Auto-reconnect** now follows the same path as a user-initiated connect.

New features
------------

- **Registration key dialog.** Added a new ``-form_key_dialog`` command-line
  option that prompts the user to enter their OpenMV Cam Registration Key (form
  key) at startup. The last-entered key is remembered via a new ``LastFormKey``
  setting, and the application exits if the dialog is cancelled or left empty.

- **Factory-programming build macros.** Added a suite of compile-time
  ``FORCE_*`` build macros that hardcode factory-programming behaviors, covering
  forced list-ports, serial-number filter, auto-connect, auto-update,
  auto-erase, auto-run, disable-stop, full-screen, resource update, form key,
  form-key dialog, and read/stall timeout overrides. This lets locked-down
  factory builds run without command-line arguments.

Bug fixes
---------

- Fixed auto-reconnect to trigger the connect action signal instead of calling
  ``connectClicked()`` directly, so reconnection follows the same path as a
  user-initiated connect.

Platform and tool support
-------------------------

- **Qt Creator base:** 10.0.1.

Breaking changes
----------------

None. This release does not change any user-facing workflow or behavior; the
new options and macros are additive.
