Bug fixes

• Swap ACCELEROMETER_RAW X and Y axis to match ACCELEROMETER readings
• Skip invalid devices ("") when searching and issue a warning instead.

Misc

• MSVC INTERPROCEDURAL_OPTIMIZATION fix
• Modified libnop library to not require MSVC conforming preprocessor anymore
• Specified minimum nlohmann version to reduce version conflicts

Release v2.14.1

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

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: #311
• Related PR: luxonis/depthai-shared#75

  • 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
