Advisories and Breaking Changes

Major breaking changes

Due to the new unmanaged memory engine, we had to redesign our pixel processing and low level memory management API-s. The most visible change is that the GetPixelRowSpan() methods have been replaced with ProcessPixelRows() variants. This was done to guarantee memory safety. For more details see:
- 2.0 documentation on Working with Pixel Buffers
- 2.0 documentation on Memory Management
- Pixel processing breaking changes & API discussion - #1739
Png and Jpeg now decode to pixels formats closer to the encoded format when using the non-generic API. (For example Jpeg now decodes to Image<Rgb24> instead of Image<Rgba32>.) This was done to reduce memory usage and remove some surprises for users.
We've dropped the old NetStandard 1.3 target. This targeted frameworks not supported by Microsoft and was adding overhead to development.

Complete list of breaking PR-s

Add Abgr32 pixel type, extend IPixel<T> - #1886 via @ynse01, @antonfirsov, @JimBobSquarePants
Remove netstandard 1.3 target - #1888 via @JimBobSquarePants
