Version 2.6.4 [Common] Added various data access methods to the Mat class, including ptr(), at(), AsSpan(), and AsSpanRowRange(). [Common] Updated get() and set() methods in the Mat class to support Span and generics, and updated MatUtils.copyFromMat() and MatUtils.copyToMat() to support Span. [Common] Added structs and ValueTuples corresponding to the data formats of basic OpenCV classes, and created overloads for methods that use these basic classes as arguments, allowing the use of structs and ValueTuples instead. This update simplifies code, enables more efficient memory usage, and improves data access speed. [Common] Added Utils.getFilePathAsyncTask() and Utils.getMultipleFilePathsAsyncTask() methods. It is an asynchronous Task return version of the existing Utils.getFilePathsAsync() method. It can be seamlessly integrated with other asynchronous code. [Common] Added Utils.texture2DToMatRaw() and Utils.matToTexture2DRaw() methods. [Common] Added methods for conversion between Mat and RenderTexture using ComputeShader (Utils.matToRenderTexture(), Utils.renderTextureToMat()). [Common] Added the WebCamTexture2MatAsyncGPUHelper class. [Common] Updated the DebugMatUtils class to support displaying Texture2D and RenderTexture. [Common] Added a face blurring feature to FaceDetectorYNExample. [iOS] Fixed an issue where AddToEmbeddedBinaries was processed redundantly with each incremental build.

Version 2.6.3 [Common]Fixed CountFingersExample. [Windows][UWP]Fixed native library build settings for ARM64 architecture.

Version 2.6.2 [Common]Changed the minimum supported version to Unity2021.3.35f1. [Common]Added AsyncGPUReadback2MatHelper. [Common]Updated MultiSource2MatHelperExample. [Common]Separated the examples using the Built-in Render Pipeline and Scriptable Render Pipeline. [Common]Fixed a memory leak in Converters.cs.

Version 2.6.1 [Common]Updated to OpenCV4.10.0. [Common]Added MultiSource2MatHelperExample.

Version 2.6.0 [iOS]Added separate plugin files for iOS for devices and simulators. [WebGL]Added plugin files with only simd enabled.

Version 2.5.9 [Common]Added PoseSkeletonVisualizer to HandPoseEstimationMediaPipeExample and PoseEstimationMediaPipeExample. [Common]Changed to use unsafe code by default. [Common]Optimized the amount of memory allocation, mainly in the Convertor class.

Version 2.5.8 [Common]Updated to OpenCV4.9.0. [Common]Added DebugMatUtilsExample and MultiObjectTrackingExample. [Common]Updated VideoWriterExample, VideoWriterAsyncExample, TextRecognitionCRNNExample, TextRecognitionCRNNWebCamExample and TrackingExample. [Common]Changed the minimum supported version to Unity2020.3.48f1. [WebGL]Added support for “WebAssembly 2023”. [iOS]Changed “Target minimum iOS Version” to 11.0. [Common]Removed TrackerGOTURN from TrackingExample and added TrackerVit.

Verson 2.5.7 [Common]Added FeatureMatchingExample. [WebGL]Added a plugin file with threads and simd enabled for the WebGL platform. This update removes support for the WebGL platform in Unity 2021.1 and below. (Select MenuItem[Tools/OpenCV for Unity/Open Setup Tools/WebGL Settings])

Version 2.5.6 [Common]Added PoseEstimationMediaPipeExample. [Common]Updated VideoWriterExample, VideoWriterAsyncExample (support URP and HDRP) .

Version 2.5.5 [Common]Updated to OpenCV4.8.0. [Common]Added ImageCorrectionExample, YuNetFaceDetectionExample and FaceDetectionYuNetV2Example. [Common]Updated HumanSegmentationExample, BarcodeDetectorExample. [Windows]Added Support for ARM64. [WebGL]Added Unity2023.2 or later support.
