v2.6.9
======

v2.6.9 adds OpenMV Pure Thermal and Arduino Nano 33 BLE Sense support, fixes
byte-swapped RGB565 framebuffer colors and Python auto-indentation, and refines
the firmware-upgrade prompt and documentation tooltips. It is built on the same
Qt Creator 4.0.2 base as the previous release, and there are no breaking changes
to existing projects.

Highlights
----------

- **OpenMV Pure Thermal** (``OPENMVPT``) is now supported, with bundled
  firmware, bootloader, and UVC binaries plus a DFU flashing entry.
- **Arduino Nano 33 BLE Sense** support adds bundled firmware and a full set of
  board, sensor, Bluetooth, audio, and thermal-camera examples.
- **Fixed byte-swapped RGB565 colors** in the live framebuffer view and video
  transcoder.
- **Fixed Python auto-indentation** so a new empty line keeps the previous
  line's indent instead of resetting to column 0.
- **"Don't show this message again"** checkbox on the firmware-out-of-date
  upgrade prompt suppresses repeated nags.

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

- **OpenMV Pure Thermal:** added support for the ``OPENMVPT`` camera
  (OpenMV Pure Thermal, STM32H743 with SDRAM), including bundled firmware,
  bootloader, and UVC binaries and a new ``boards.txt`` entry for DFU flashing
  (`c5b7df59f <https://github.com/openmv/qt-creator/commit/c5b7df59f>`__).
- **Arduino Nano 33 BLE Sense:** bundled the Nano 33 BLE Sense firmware
  (`c5b7df59f <https://github.com/openmv/qt-creator/commit/c5b7df59f>`__) and
  added a full set of examples covering the board I2C scanner, the APDS9960,
  HTS221, LPS22, and LSM9DS1 sensors, BLE blinky/scan/temperature, audio FFT,
  and the thermal camera
  (`4e7bc157b <https://github.com/openmv/qt-creator/commit/4e7bc157b>`__).

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

- The firmware-out-of-date upgrade prompt now includes a **"Don't show this
  message again"** checkbox so users can suppress repeated upgrade prompts
  (`dd1ad68c4 <https://github.com/openmv/qt-creator/commit/dd1ad68c4>`__).
- Ctrl-clicking a method or attribute now shows only the documentation tooltip
  for that specific module, by filtering matches to the module name preceding
  the ``.``
  (`34d9a30bf <https://github.com/openmv/qt-creator/commit/34d9a30bf>`__).
- Examples submenu labels now display hyphens in folder names as spaces for
  cleaner titles (for example ``Nano 33 BLE Sense`` and ``Portenta H7``)
  (`34d9a30bf <https://github.com/openmv/qt-creator/commit/34d9a30bf>`__,
  `4e7bc157b <https://github.com/openmv/qt-creator/commit/4e7bc157b>`__).
- On Linux, the **DFU Util** and **Convert Video** progress dialogs now open
  without stealing window focus
  (`dd1ad68c4 <https://github.com/openmv/qt-creator/commit/dd1ad68c4>`__).
- The **TV Shield** example was updated to use SIF (352x240) resolution,
  optional triple buffering, and an FPS printout, and now notes that a wired TV
  shield is also supported; the same change also tidied the Portenta H7 LoRa
  example by dropping the explicit OTAA join timeout argument
  (`d54bb97e4 <https://github.com/openmv/qt-creator/commit/d54bb97e4>`__).

Bug fixes
---------

- Fixed RGB565 framebuffer colors appearing byte-swapped: images from older
  firmware (before 3.8.0) are byte-reversed while newer firmware is sent
  non-reversed, in both the live view and the video transcoder
  (`dd1ad68c4 <https://github.com/openmv/qt-creator/commit/dd1ad68c4>`__).
- Fixed incorrect Python auto-indentation by keeping the previous line's indent
  on the new empty line instead of resetting to column 0 after a blank line
  (`c33e9f354 <https://github.com/openmv/qt-creator/commit/c33e9f354>`__).
- Error-message click navigation no longer tries to open a nonexistent source
  file when the error originates from a built-in (frozen) module, avoiding
  spurious editor errors
  (`dd1ad68c4 <https://github.com/openmv/qt-creator/commit/dd1ad68c4>`__).

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

- **Qt Creator base:** 4.0.2.
- **New board:** OpenMV Pure Thermal (``OPENMVPT``, STM32H743 with SDRAM) with
  bundled firmware, bootloader, and UVC binaries
  (`c5b7df59f <https://github.com/openmv/qt-creator/commit/c5b7df59f>`__).
- **New board:** Arduino Nano 33 BLE Sense with bundled firmware
  (`c5b7df59f <https://github.com/openmv/qt-creator/commit/c5b7df59f>`__).
- **Bundled firmware:** OpenMV firmware updated 3.8.0 to 3.9.1
  (`c5b7df59f <https://github.com/openmv/qt-creator/commit/c5b7df59f>`__) and
  then to 3.9.2
  (`a707f6ebc <https://github.com/openmv/qt-creator/commit/a707f6ebc>`__).
- **IDE version:** bumped from 2.6.8 to 2.6.9
  (`d128254d7 <https://github.com/openmv/qt-creator/commit/d128254d7>`__).

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

None. This release adds boards and fixes without changing existing project
behavior, and the Qt Creator 4.0.2 base is unchanged.
