v1.5.2
======

v1.5.2 is a feature and refresh release built on Qt Creator 4.0.2. It teaches
the framebuffer viewer to decode JPEG-compressed frames, adds a configurable
serial terminal tab size, declutters the Options dialog for OpenMV users, and
refreshes the bundled OpenMV Cam firmware to 2.3.0 along with a batch of new
example scripts. There are no breaking changes.

Highlights
----------

- **JPEG framebuffer decoding:** the framebuffer viewer now decodes and
  displays JPEG-compressed frame buffers, not just raw RGB, grayscale, and
  binary frames.
- **Bundled firmware 2.3.0:** the OpenMV Cam firmware shipped for both OMV2
  and OMV3 boards was updated to version 2.3.0.
- **Serial Terminal Tab Size** is now a configurable setting that applies live
  to the serial terminal instead of a hardcoded tab width of 8.
- **Decluttered Options dialog:** unused Qt Creator settings are hidden for
  OpenMV users and the ``Font & Colors`` page is renamed to ``Font``.
- **New bundled examples** for Pixy emulation, MAVLink, barcodes, and a WiFi
  MJPEG streamer.

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

- The framebuffer viewer can now decode and display JPEG-compressed frame
  buffers received over the 6-bit serial encoding, building the pixmap via
  ``QImage::fromData`` (`848215da8
  <https://github.com/openmv/qt-creator/commit/848215da8>`__).
- Added new bundled **Pixy emulation** examples that turn the OpenMV Cam into a
  Pixy-compatible AprilTag and blob tracker over I2C, SPI, and UART
  (`b3dac4090 <https://github.com/openmv/qt-creator/commit/b3dac4090>`__).
- Added new bundled **MAVLink** examples for streaming optical flow and
  AprilTag landing-target messages to a flight controller (`b3dac4090
  <https://github.com/openmv/qt-creator/commit/b3dac4090>`__).
- Added bundled examples for 1D barcode detection
  (EAN/UPC/ISBN/CODE39/CODE93/CODE128/etc.) and a WiFi MJPEG streamer that
  runs in Access Point mode (`b3dac4090
  <https://github.com/openmv/qt-creator/commit/b3dac4090>`__).

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

- Added a configurable **Serial Terminal Tab Size** setting to the editor
  Tab/Indentation options page; the value is persisted and applied live to the
  serial terminal (`848215da8
  <https://github.com/openmv/qt-creator/commit/848215da8>`__).
- Script execution in the terminal now sends the program to the camera one byte
  at a time to avoid overrunning the MicroPython board's input buffer
  (`848215da8 <https://github.com/openmv/qt-creator/commit/848215da8>`__).
- Decluttered the Options dialog for OpenMV users by hiding unused Qt Creator
  settings (encodings, mouse hiding and navigation, scroll-wheel zoom,
  camel-case and smart selection, auto-fold first comment, open-links-in-split,
  file-encoding display, antialiasing, and color scheme) and renamed the
  ``Font & Colors`` page to ``Font``; auto-folding of the first comment is now
  disabled by default in addition to being hidden (`848215da8
  <https://github.com/openmv/qt-creator/commit/848215da8>`__).
- Changed the default so that on-save whitespace cleaning now applies to the
  entire document instead of only edited lines (`848215da8
  <https://github.com/openmv/qt-creator/commit/848215da8>`__).
- Expanded the bundled offline documentation with new I/O and LED control
  tutorials, a high-resolution pinout image, and updated image and network
  library reference pages (`b3dac4090
  <https://github.com/openmv/qt-creator/commit/b3dac4090>`__).

Bug fixes
---------

- Fixed Python syntax highlighting of function-call arguments so that
  keyword-argument names highlight correctly and the ``=`` separator is treated
  as normal text (`848215da8
  <https://github.com/openmv/qt-creator/commit/848215da8>`__).

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

- **Qt Creator base:** 4.0.2.
- **Bundled OpenMV Cam firmware:** updated to 2.3.0 for both OMV2 and OMV3
  boards (`b3dac4090
  <https://github.com/openmv/qt-creator/commit/b3dac4090>`__).

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

None. This release introduces no user-visible workflow or behavior breaks;
existing projects continue to work unchanged.
