v3.0.3
======

v3.0.3 adds first-class support for the NXP i.MX RT1060 (EVKB-MIMXRT1060)
board, including a serial bootloader (SBL) repair-and-reflash flow, alongside an
Auto Reconnect toggle, an RTSP stream player, and improvements to the Import
Helper and code-completion docstring parsing. The release is built on Qt
Creator 4.0.2, bumps the bundled OpenMV firmware to v4.4.2, and contains no
breaking changes for user projects.

Highlights
----------

- **NXP i.MX RT1060 support.** The EVKB-MIMXRT1060 board is now recognized and
  can be flashed directly from the IDE.
- **SBL bootloader repair flow.** A working serial download (``blhost``)
  bootloader flow can repair and reflash i.MX RT1060-based cameras, with an
  optional flash-filesystem erase.
- **Auto Reconnect to OpenMV Cam.** A new ``Tools`` toggle reconnects to the
  camera automatically when it is detected, without stopping the running
  script.
- **Play RTSP Stream.** A new ``Video Tools`` item plays a live RTSP stream via
  ``ffplay``.
- **Import Helper for nested modules.** Modules in non-flat folder hierarchies
  are now imported and copied to the OpenMV Cam correctly.

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

- **NXP i.MX RT1060** support adds a dedicated firmware flash loader that drives
  the bundled ``sdphost``/``blhost`` tools to program the EVKB-MIMXRT1060 over
  USB, with a new ``imx.txt`` config and ``boards.txt`` entry
  ``OMVRT60_IMXRT60_32768_SDRAM``
  (`6a040cda3 <https://github.com/openmv/qt-creator/commit/6a040cda3>`__,
  `e72ff6f52 <https://github.com/openmv/qt-creator/commit/e72ff6f52>`__).
- **SBL bootloader flow** lets users repair and reflash i.MX RT1060-based
  cameras over the i.MX secondary bootloader, with an optional flash-filesystem
  erase (driven by the existing erase action) when reflashing
  (`0bb648c94 <https://github.com/openmv/qt-creator/commit/0bb648c94>`__,
  `da591b7c9 <https://github.com/openmv/qt-creator/commit/da591b7c9>`__,
  `c08022fab <https://github.com/openmv/qt-creator/commit/c08022fab>`__).
- **Auto Reconnect to OpenMV Cam**, a checkable ``Tools`` menu item, reconnects
  to the camera automatically when detected without stopping the running
  script; the state is persisted across sessions and disables the manual
  ``Connect``/``Disconnect`` actions while active
  (`0546d806e <https://github.com/openmv/qt-creator/commit/0546d806e>`__).
- **Play RTSP Stream**, a new ``Video Tools`` item (non-Linux), prompts for an
  IP/domain, port (default 554), and TCP-vs-UDP transport, then plays the live
  ``rtsp://`` stream via ``ffplay``
  (`f6a39055d <https://github.com/openmv/qt-creator/commit/f6a39055d>`__).
- **MicroSpeech examples** for Yes/No keyword spotting were added for the Nicla
  Vision and Portenta H7 boards
  (`8cecde656 <https://github.com/openmv/qt-creator/commit/8cecde656>`__).

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

- The **Import Helper** now imports and copies modules in nested (non-flat)
  folder hierarchies correctly, computing dotted module names from relative
  paths and copying folders recursively;
  ``Documents``-folder modules override ``Examples`` modules
  (`e5696f6f8 <https://github.com/openmv/qt-creator/commit/e5696f6f8>`__,
  `33a703157 <https://github.com/openmv/qt-creator/commit/33a703157>`__,
  `1e4a27769 <https://github.com/openmv/qt-creator/commit/1e4a27769>`__).
- **Code-completion docstring parsing** now extracts function argument
  signatures correctly, including stripping optional-argument ``[...]`` markup
  from the bundled HTML documentation
  (`75cb80a09 <https://github.com/openmv/qt-creator/commit/75cb80a09>`__,
  `05125bec8 <https://github.com/openmv/qt-creator/commit/05125bec8>`__,
  `16fde1c1e <https://github.com/openmv/qt-creator/commit/16fde1c1e>`__).
- **Connect/disconnect reliability** improved: the text- and image-buffer
  draining loops now always run, with only ``scriptStop`` gated by the Auto
  Reconnect state, so buffers drain cleanly whether or not auto-reconnect is
  enabled
  (`6673302e1 <https://github.com/openmv/qt-creator/commit/6673302e1>`__).

Bug fixes
---------

- Fixed several i.MX RT flashing bugs: file paths were passed as literal strings
  instead of resolved paths, the ``sdphost`` jump command was misspelled
  ``jump-adress``, and the bootloader flasher binary name was corrected
  (`0bb648c94 <https://github.com/openmv/qt-creator/commit/0bb648c94>`__,
  `c08022fab <https://github.com/openmv/qt-creator/commit/c08022fab>`__).
- Corrected a typo in the update-available dialog text, ``reources`` to
  ``resources``
  (`798f55c31 <https://github.com/openmv/qt-creator/commit/798f55c31>`__).

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

- **Qt Creator base:** 4.0.2.
- **New board:** NXP i.MX RT1060 (EVKB-MIMXRT1060), board entry
  ``OMVRT60_IMXRT60_32768_SDRAM`` (firmware folder ``EVKBMIMXRT1060``)
  (`6a040cda3 <https://github.com/openmv/qt-creator/commit/6a040cda3>`__,
  `e72ff6f52 <https://github.com/openmv/qt-creator/commit/e72ff6f52>`__).
- **Bundled OpenMV firmware:** updated to v4.4.2 (via an interim 4.3.3 bump),
  with refreshed firmware/uvc/bootloader binaries for OPENMV2/3/4/4P/4_PRO/PT,
  NANO33, NICLAV, PORTENTA, and NANO_RP2040
  (`8cecde656 <https://github.com/openmv/qt-creator/commit/8cecde656>`__,
  `292950b60 <https://github.com/openmv/qt-creator/commit/292950b60>`__).
- **Bundled NXP tools:** ``blhost`` and ``sdphost`` are now marked executable on
  Linux and macOS so the i.MX bootloader flow can run them
  (`3c464ca5a <https://github.com/openmv/qt-creator/commit/3c464ca5a>`__).

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

None. This release introduces no breaking changes for user projects; the Qt
Creator base remains Qt Creator 4.0.2.
