10.3.1

Zielon/INSTA10.3.1Aug 15, 2026by github-actions[bot]

AI Summary

This release focuses on bug fixes and performance improvements, addressing issues with path handling, line drawing (including tension and bezier curves), color parsing, and arc rendering. It also includes optimizations for text rendering and transformer operations.

Key Highlights

Fixed `getPointAtLength` to return the last point for closed paths.
Fixed `Arc.getSelfRect` to correctly report full circles for zero-degree arcs.
Enhanced color parsing to support HSL hues, RGB percentages, and the 'transparent' named color.
Fixed bounding box calculations for lines with tension and multi-segment bezier curves.
Performance improvements for text rendering and transformer operations.
