+## [0.5.26](https://github.com/nicklockwood/Euclid/releases/tag/0.5.26) (2022-07-24)
+
+- SceneKit meshes are now more reliably sealed at import time
+- Improved triangulation/tessellation of complex convex polygons
+- Fixed case where `loft` could produce a mesh with redundant back-face polygons
+- You can now create `Path`s with a single point (useful when lofting)
+- Fixed crash when lofting zero-scale path
+- Fixed assertion failure when scaling path by zero vector
+- Reduced false negatives when comparing `Plane` equality
+- Improved performance of uniform `Plane` scaling
+- Added `Sendable` conformance to all applicable types when building with Xcode 14
+- Converted unintended static `var` values to `let`
+- Fixed warnings in Xcode 14 beta
+
 ## [0.5.25](https://github.com/nicklockwood/Euclid/releases/tag/0.5.25) (2022-07-03)
 
 - Added `Mesh.submeshes` property
