v4.2.1#

v4.2.1 is a maintenance release that refreshes the bundled OpenMV firmware to v4.5.8 across every supported board. It remains based on Qt Creator 10.0.1, and also adjusts the Windows code-signing script alongside the version bump. There are no breaking changes.

Highlights#

  • Bundled firmware updated to v4.5.8 for all supported boards, so the IDE ships the latest OpenMV firmware out of the box.

Other changes and improvements#

  • Updated the bundled OpenMV firmware from v4.5.6 to v4.5.8 for all supported boards (OPENMV2/3/4/4P/PT, OPENMV_RT1060, Arduino GIGA, Nano RP2040 Connect, Nicla Vision, Portenta H7, and Nano 33 BLE Sense), including the firmware.bin/.dfu/.uf2/.hex, UVC, and bootloader binaries (4ef02d2a6).

  • Stopped code-signing bundled .dll files on Windows in scripts/sign.py, signing only .exe binaries to reduce per-signature costs (9ff6990b8).

Platform and tool support#

  • Qt Creator base: 10.0.1.

  • OpenMV IDE version: bumped to 4.2.1 (85928e586).

  • OpenMV firmware: v4.5.6 -> v4.5.8 for all supported boards.

Breaking changes#

None. This release does not change any IDE workflows or behavior for existing projects.
