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 2.6.4 [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 1.3.2 [iOS]Fixed libopencvforunity.a Bitcode Setting. [Common]Added Beta16 Version of “OpenCV for Untiy” based on “OpenCV3.0.0”.
