v4.8.10
=======

v4.8.10 adds support for the OpenMV AE3 board and refreshes the bundled AI
toolchains, updating the Ethos-U Vela NPU compiler to 5.0.0 and the ST Edge AI
tools to 4.0.0. This release remains based on Qt Creator 14.0.2, with no
rebase, and contains no breaking changes.

Highlights
----------

- **OpenMV AE3** Alif Ensemble E3 board is now supported, including
  ``alif_tools`` bootloader/DFU programming and per-core Ethos-U55 NPU
  acceleration.
- **Ethos-U Vela** NPU model compiler updated from 4.2.0 to 5.0.0, rebuilt
  against the Python 3.13 ABI.
- **ST Edge AI** (``stedgeai``) model conversion tools updated from 3.0.0 to
  4.0.0 on all platforms.
- **Faster connection fallback:** the IDE now gives up on a failed camera
  connection after 2 reconnect attempts instead of 10.

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

- **OpenMV AE3** Alif Ensemble E3 board support (internal codename "AE3
  classic"). Adds the ``AE3`` / ``OPENMV AE3 SBL2`` board type, with the IDE
  display name ``OpenMV AE3 SBL2`` (VID:PID ``37C5:16E3``), ``alif_tools``
  bootloader/DFU programming, a dual-core (HP/HE) romfs layout, and per-core
  Ethos-U55 Vela NPU acceleration configs (High Performance Core
  ``ethos-u55-256``, High Efficiency Core ``ethos-u55-128``). The board is a
  hidden/DFU-programmed target reached via its bootloader VID:PID mappings
  rather than a normally listed selectable connect target

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

- Reduced the maximum number of automatic camera reconnect attempts from 10 to
  2, so the IDE gives up faster on a failed connection
  (`2ddecec53 <https://github.com/openmv/qt-creator/commit/2ddecec53>`__).
- Updated the bundled **Ethos-U Vela** NPU model compiler from 4.2.0 to 5.0.0
  on Windows, Linux, and macOS arm64, rebuilt against the Python 3.13 ABI with
  the ``regor`` and ``mlw_codec`` binaries recompiled and the bundled
  ``numpy`` updated to 2.4.4 across all platforms
  (`be9d29d9d <https://github.com/openmv/qt-creator/commit/be9d29d9d>`__,

- Updated the bundled **ST Edge AI** (``stedgeai``) model conversion tools
  from 3.0.0 to 4.0.0 on Windows, Linux, and macOS arm64

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

- **Qt Creator base:** 14.0.2.
- **New board:** OpenMV AE3 SBL2 (Alif Ensemble E3), a hidden/DFU-programmed
  target programmed via ``alif_tools`` with dual-core Ethos-U55 NPU
  acceleration.
- **Ethos-U Vela** NPU compiler: 4.2.0 -> 5.0.0 (Windows, Linux, macOS arm64),
  reinstalled against the Python 3.13 ABI.
- **ST Edge AI** (``stedgeai``) tools: 3.0.0 -> 4.0.0 (Windows, Linux, macOS
  arm64).
- **Bundled numpy** (Vela environment): updated to 2.4.4 on all platforms.

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

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