Apr 1, 2026April 2026 (2026-04): Delivered RTL text rendering improvements and configurable word-boundary line breaking for galacean/effects-runtime. Refactored line-breaking logic to separate RTL and LTR paths, implemented word-based line breaking across all text types, and introduced a wordBreak option to control wrapping behavior. These changes enhance internationalization support, provide consistent text wrapping across locales, and establish a foundation for more robust multilingual rendering.

Feb 1, 2026February 2026: Focused stability and memory-management improvements in the effects-runtime video subsystem, delivering a robust lifecycle cleanup and precise end-state handling. Implemented fixes that prevent memory leaks, ensure proper resource cleanup on component destruction, and correct end-state determination. Also introduced safeguards by clamping currentTime to non-negative values to avoid negative playback times.
