Add

• Rewrite SwiftUI support based on @StateObject instead of the old @ObservedObject. It provides a stable and better data model backs the image rendering in SwiftUI. For this, Kingfisher SwiftUI supports from iOS 14 now. #1707
• Mark ImageCache.retrieveImageInMemoryCache(forKey:options:) as open to expose a correct override entry point to outside. #1703
• The NSTextAttachment extension method now accepts closure instead of a evaluated view. This allows delaying the passing in view to the timing which actually it is needed. #1746
• A KFAnimatedImage type to display a GIF image in SwiftUI. #1705
• Add a progress parameter to the KFImage's placeholder closure. This allows you create a view based on the loading progress. #1707
• Now KFAnimatedImage also supports configure modifier so you can set options to the underhood AnimatedImageView. #1768
• Expose AnimatedImageView fields to allow consumers to observe GIF progress. #1789 @AttilaTheFun
• An option to pass in an write option for writing data to the disk cache. This allows writing cache in a fine-tuned way, such as .atomic or .completeFileProtection. #1793 @ignotusverum

Fix

• Uses UIGraphicsImageRenderer on iOS and tvOS for better image drawing. #1706
• An issue that prevents Kingfisher compiling on mac Catalyst target in some certain of Xcode versions. #1692 @kvyatkovskys
• The KF.retry(:_) method now accepts an optional value. It allows to reset the retry strategy by passing in a nil value. #1729
• The placeholder view builder of KFImage now works when it gets changed instead of using its initial value forever. #1707
• Some minor performance improvement. #1739 @fuyoufang
• The LocalFileImageDataProvider now loads data in a background queue by default. This prevents loading performance issue when the loading is created on main thread. #1764 @ConfusedVorlon
• Respect transition for SwiftUI view when using KFImage. #1767
• A type of AuthenticationChallengeResponsable. Now use AuthenticationChallengeResponsible instead. #1780 @fakerlogic
• An issue that AnimatedImageView dose not change the tintColor for templated images. #1786 @leonpesdk
• A crash when loading a GIF image in iOS 13 and below. #1805 @leonpesdk

Remove

• Drop support for iOS 10/11, macOS 10.13/10.14, tvOS 10/11 and watch OS 3/4. #1802
• The workaround of KFImage.loadImmediately is not necessary anymore due to the model switching to @StateObject. The interface is kept for backward compatibility, but it does nothing in the new version. #1707
