v4.1.8
======

v4.1.8 is a maintenance release that bundles OpenMV firmware and examples
v4.5.5 and fixes the ``FORCE_FULL_SCREEN`` build configuration. It remains
based on Qt Creator 10.0.1, and there are no breaking changes.

Highlights
----------

- **Bundled firmware v4.5.5** for all supported OpenMV and Arduino boards,
  with refreshed firmware, bootloader, and UVC binaries.
- **Updated example scripts** migrated to the new image hint API and the new
  ``img.to_jpeg()`` JPEG API.
- **FORCE_FULL_SCREEN fix** so the forced-fullscreen build now compiles and
  runs correctly.

Other changes and improvements
------------------------------

- Bundled OpenMV firmware and examples updated to **v4.5.5** across all boards
  (OpenMV M2/M3/H7/H7 Plus/PT/RT1060, Arduino Giga/Portenta H7/Nicla
  Vision/Nano RP2040 Connect/Nano 33 BLE Sense), including refreshed
  firmware/bootloader/UVC binaries. Example scripts were migrated to the new
  image hint API (used by ``image.scale()``, ``to_rainbow()``, ``to_jpeg()``,
  etc.) with constants such as ``image.AREA``, ``image.ROTATE_180``, and
  ``image.VFLIP``/``HMIRROR``/``TRANSPOSE``, replacing ``mean_pooled()``,
  ``replace()``, and ``assign()``. The examples also migrated the deprecated
  JPEG API, replacing ``img.compress()`` and ``frame.compressed()`` with
  ``img.to_jpeg()`` and ``to_jpeg(copy=True)`` across the Time-of-Flight,
  thermal, RPC remote-control, MJPEG streamer, and board ``usb_vcp.py``
  examples
  (`0604d5284 <https://github.com/openmv/qt-creator/commit/0604d5284>`__).

Bug fixes
---------

- Fixed the ``FORCE_FULL_SCREEN`` build configuration so the forced-fullscreen
  code block compiles and runs correctly by moving the opening brace outside
  the preprocessor ``#else``/``#endif`` guard, ensuring both the
  ``FORCE_FULL_SCREEN`` and ``-full_screen`` argument paths share the same
  block
  (`4354cf8f4 <https://github.com/openmv/qt-creator/commit/4354cf8f4>`__).

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

- **Qt Creator base:** 10.0.1.
- **Bundled firmware and examples:** updated to v4.5.5 (from v4.5.4).

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

None. This release bundles new firmware and a build fix; existing IDE projects
and workflows are unaffected.
