v3.5.1
======

v3.5.1 fixes the TensorFlow ``conv2d`` / ``sepconv3`` operations, updates
TensorFlow and :mod:`ulab`, and improves image-format error messages. It
introduces **no breaking API changes** — v3.5.0 scripts run unchanged.

Highlights
----------

- **TensorFlow fixes** — corrected ``conv2d`` and ``sepconv3`` boundary
  handling, plus a TensorFlow update.
- **Clearer errors** — more specific image-format error messages.
- **No breaking API changes** — reflash and your v3.5.0 scripts run
  unchanged.

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

- Updated TensorFlow and :mod:`ulab`; disabled :mod:`ulab` on the OpenMV 2 (M4,
  which lacks the space for it) and the WiFi debug feature on older boards
  (especially the OpenMV 3); removed unused submodules; updated the WiFi
  firmware-update script.

Bug fixes
---------

Machine learning:

- Fixed the TensorFlow library ``conv2d`` and ``sepconv3`` boundary handling.

Imaging:

- Fixed the ``mutable_bayer`` error message and made image-format errors more
  specific.

System:

- Fixed debug-build linker errors.

Breaking API changes
--------------------

v3.5.1 introduces **no breaking Python API changes**. Scripts that ran on
v3.5.0 run unchanged on v3.5.1 — just reflash the firmware. (Note: :mod:`ulab` is
not available on the OpenMV 2 due to its limited flash.)
