v4.4.1
======

v4.4.1 is a small patch release that polishes the editing experience and
hardens the camera connection. Autocompletion no longer triggers inside
comments and strings, the new-script template is modernized to current
MicroPython style, and serial polling is tuned for stability. This release
remains based on Qt Creator 14.0.2. There are no scripting API changes, but a
one-time settings reset occurs when upgrading from older versions.

Highlights
----------

- **No autocompletion in comments or strings.** Code-assist no longer pops up
  while the cursor is inside a ``#`` comment or a quoted string in ``.py``
  files.
- **Modernized new-script template.** The default ``Untitled`` template now
  uses current MicroPython style with separate ``import`` lines, a
  space-free ``sensor.skip_frames(time=2000)``, and a bare ``while True:``
  loop.
- **Tuned serial polling.** Framebuffer, state, and TX-buffer query intervals
  were increased to reduce serial traffic and improve camera stability.
- **Recoverable stuck connections.** The ``get_state`` command can again be
  used to unstick a stalled serial connection.

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

- The default new-script template was modernized to current MicroPython
  style: separate ``import sensor`` and ``import time`` lines,
  ``sensor.skip_frames(time=2000)`` without spaces, and a bare
  ``while True:`` loop.

Bug fixes
---------

- Autocompletion no longer pops up inside Python comments or string literals.
  The code-assist activation now scans the text from the start of the
  document up to the cursor and suppresses completion when the cursor ends up
  inside a ``#`` comment or a single- or double-quoted string.
  (`41b324978 <https://github.com/openmv/qt-creator/commit/41b324978>`__)
- Increased polling intervals for framebuffer, state, and TX-buffer queries
  (``FRAME_SIZE_DUMP`` and ``GET_STATE`` from 5ms to 50ms, ``GET_TX_BUFFER``
  from 5ms to 20ms) to reduce serial traffic and improve stability with the
  camera.
  (`195715061 <https://github.com/openmv/qt-creator/commit/195715061>`__)
- Re-enabled using the ``get_state`` command to recover a stuck serial
  connection (the previously hard-disabled path is now controlled by
  ``m_unstuckWithGetState``) and fixed the unstuck timer to restart
  correctly.
  (`aab1e1e2e <https://github.com/openmv/qt-creator/commit/aab1e1e2e>`__)
- On startup the IDE now wipes its stored user settings, resetting to
  defaults, when the saved resources version is older than 4.4.0, preventing
  incompatible old settings from breaking the app.

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

- **Qt Creator base:** 14.0.2.

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

User settings are reset to defaults on the first launch of v4.4.1 when
upgrading from a version whose stored resources are older than 4.4.0. This is
a one-time settings wipe and does not affect your scripts or projects.
