Nov 1, 2025November 2025 focused on delivering cross-platform UI enhancements, improving reliability, and expanding internationalization support for Slint. Key feature work included conic-gradient rotation via the 'from' angle across all renderers, and a more usable printer demo with a resizable window and minimum dimensions. In WASM builds, I18n and dynamic CJK font loading were added to enable broader language support. Stability work reduced startup and resize panics (wgpu with zero-dim surfaces), and embedded/build reliability and documentation were improved for STM32 targets. These changes collectively increase business value by enabling richer visual design, broader user reach, and more predictable behavior across platforms.
