Version 2.2.1[Common]Updated to OpenCV3.3.0.[Common]Added dnn module.(win,mac,ios,android platform)[Common]Added img_hash, reg, text module.(all platform)[Common]Added MobileNetSSDExample, MobileNetSSDWebCamTextureExample, TensorFlowWebCamTextureExample, ThinPlateSplineShapeTransformerExample, TextDetectionExample, VideoWriterExample.[Common]WindowsStoreApp8.1 & WindowsPhone8.1 support have been deprecated.

Version 2.5.0 [Common]Added TransformECCExample, HumanSegmentationExample and ImageClassificationPPResnetExample.v [Common]Update TextOCRWebCamExample. [Common]Changed the setup procedure to use the SetupToolsWindow. [Common]Change the namespase under “OpenCVForUnity/Editor” folder from “OpenCVForUnity” to “OpenCVForUnity.Editor”. [Common]Added the ExampleAssetsDownloaderWindow that automatically downloads the necessary files to Examples. [Common]Added “OpenCVForUnity” folder under “StreamingAssets” folder. [Common]Added function to automatically move the StreamingAssets folder. [WebGL]Added Unity2022.2 or later support.

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.
