๐ Features
Thumbnail Decoding
- ๐ Supports to load the large web image with thumbnail, control the limit size and aspect ratio #2922 #2810
- ๐ Better than resize transformer, which does not allocate full pixel RAM and faster on CPU. If you've already use transformer to generate thumbnail, you'd better have a try

Core Image

- For CIImage based UIImage/NSImage, using the CIFilter to take shortcut, which is faster and lazy (rasterize on demand)
Cache

๐ Performances
- Using UIGraphicsImageRenderer on iOS 10+, save memory when image bitmap is RGB(-25%) or Grayscale(-75%) #2907
- ๐ Provide the polyfill APIs for firmware iOS 10- and macOS. If you already use
SDGraphicsBeginImageContext
for drawing, you'd better replace that instead.
๐ Fixes
