Highlights

SkiaSharp 2.80.4 is a focused servicing update for the 2.80 line. It tightens text rendering behavior, makes failed surface allocations degrade more safely, and fixes up Windows ANGLE packaging so the native dependencies arrive together.

Breaking Changes

None in this release.

Bug Fixes

Rendering

• Consistent anti-aliasing and edging — IsAntialias now also controls the edging behavior, bringing text rendering into line with caller expectations. (#1802)
• Safer allocation failures — Surface allocation failures now return an empty surface instead of failing more abruptly. ❤️ @richirisu (#1784)

Platform

• Windows ANGLE packaging fix — The ANGLE distribution now includes its additional zlib1.dll dependency. (#1807)
