• IMX378 camera driver can also handle now IMX380 and IMX577 sensors, besides IMX477

Bug fixes

• FW Bug Fixes for PoE stability issues
• Modified default Script processor from MSS to CSS (stability improvement measure)
• Swap ACCELEROMETER_RAW X and Y axis to match ACCELEROMETER readings
• Skip invalid devices ("") when searching and issue a warning instead.
• Default orientation corrected on OAK-1 Lite and some newer OAK-1 devices (was upside down)
• 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
• Specified minimum nlohmann version to reduce version conflicts
• Documented and exposed many more environment variables to control library behavior
• Enabled queue size of zero for callback only operation
• Memory usage optimizations when ColorCamera still output is not used

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
  • Temporal filter
  • Speckle filter
  • Decimation filter
  • Threshold filter
• FeatureTracker: Add support for 4k/12MP inputs
• Add IMU support for CM4-POE board

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
• Related PR: luxonis/depthai-core#311

Release v2.13.3.0

Features

• Added manual white balance (color temperature) camera control
• Creating prebuilt Python wheels also for Raspberry Pi OS 'bullseye' (Python 3.9)

Bug fixes

• Firmware:
  • Fix a potential crash when VideoEncoder is used (regression from v2.13.0.0)
  • Fix a crash when more than 4x VideoEncoder instances are created
  • Fix a StereoDepth crash with RGB-depth alignment and missing RGB calibration (having the latest calib v6)
  • Fix RGB-depth alignment when running at full mono camera resolution
• XLink:
  • Fix a potential segmentation fault on device close
  • Fix some incorrectly calculated timeouts (on wait for reset)

Misc

• Code changes: #443; luxonis/depthai-core#288;

Known issues

• OAK-D Lite
  • FPS currently fixed to 30
  • Auto-exposure flicker may be seen on Mono cameras
