Release v2.15.5.0

Bug fixes

• Updated FW with EEPROM fixes
• Fixed nlohmann json < v3.9.0 compatibility
• Fixed intermediary toolchain generation

Release v2.15.4.0

Features

• OV7251 (OAK-D Lite mono camera) configurable FPS (#566)
• Eeprom version v7
• Improve PoE throughput and latency for some usecases (#538)

Bug fixes

• Regression: setLoadMesh didn't overwrite useHomographyRectification behavior (337a746)
• VideoEncoder:
  • fix keyframe (IDR) rate config (before it didn't change from the default of 30)
  • fix resource computations for JPEG (preset FPS per instance was hardcoded to 30, it didn't allow video MJPEG at 4K 30fps + still 12MP at about 1fps). The encoder limit for JPEG is about 450.. 460 MPix/s
• Fixed incorrect stereo calibration for 2 batches of OAK-D-LITEs. Board revisions affected: boardName = OAK-D-LITE; boardRev = R1M1E1 and R0M0E0. If incorrect depth measurements were observed it's highly recommended updating to this version.

Misc

• Stereo: Auto enable distortion correction for fisheye lenses (#576)
• Stereo: Enable RGB alignment in examples where inference is performed on RGB camera (#567)

• Fix for focus control not working with some IMX477 cameras

Misc

• MSVC INTERPROCEDURAL_OPTIMIZATION fix
• Modified libnop library to not require MSVC conforming preprocessor anymore

Release v2.14.1.0

Features

• Added checks for StereoDepth if input/output messages are not connected as expected

Bugs

• Fixed regression from 2.14.0.0 for ColorCamera, StereoDepth initial config
• Edge case fixes for StereoDepth: post-processing + median OFF + disparity only triggered a crash

Misc

Release v2.14.0.0

Features

• Added watchdogInitialDelayMs to PrebootConfig, for the host to set optionally and override the device defaults, currently 8s for USB, 15s for Ethernet.
• Added libnop as serialization library instead of nlohmann, reducing CPU usage on both host and device side
• Added IO groups (Allows same names in different IO maps: node.inputs['test1'], node.passthroughs['test1']
• Added IO option waitForMessage to control this behavior
• Implemented stereo depth post processing filters:
  • Spatial filter

Bug fixes

• Fix an issue with watchdog timeout being overridden to 1.5s for Ethernet case. Normally the device will choose 1.5s for USB, 4s for Ethernet. Might have been a cause for watchdog induced crashes in case of network congestion, but not confirmed.
• XLink related fixes. Thanks to @diablodale
• Fix for Stereo HW desync when extended mode is enabled

Misc

• Fix typo: assigment -> assignment in ObjectTracker node
• Code changes: #472
