Version 1.60.0

Skia m60 upgrade with new platform support · Released February 23, 2018 · NuGet · GitHub Release

Highlights

SkiaSharp 1.60.0 upgrades to Skia milestone 60, bringing major improvements to GPU-backed rendering and texture-based surfaces. This release also introduces preview support for Apple watchOS and GTK#, and cleans up the API surface by removing previously obsoleted types and members.

Breaking Changes

• Removed many obsolete types and members that were previously marked with [Obsolete]. Code referencing these removed APIs will need to migrate to their recommended replacements.
• Removed confusing and incorrect SKCanvas overloads that could produce unexpected results.
