Jun 1, 2025June 2025: Delivered key texture group improvements in YoYoGames/GameMaker-HTML5. Added texturegroup_exists utility to verify texture group presence by name; stabilized HTML5 API by introducing safe stubs for texturegroup_add and texturegroup_delete and replacing silent no-ops with console error logging. These changes reduce crash risk, improve developer feedback, and lay groundwork for future API refinement across HTML5 builds.

Jan 1, 2025January 2025 monthly summary for YoYoGames/GameMaker-HTML5. Focused on stabilizing text rendering and improving cross-runner consistency to deliver a more reliable UX across HTML5 and IDE-style runners. Implemented robust text block splitting with synchronized newline interpretation against the C++ runner and added boundary checks to prevent out-of-bounds reads, reducing edge-case crashes and formatting glitches. Introduced a half-pixel spread parameter for SDF font rendering, extended yyFontManager to manage SDF shader uniforms (gm_SDF_Dist_UV basic and gm_SDF_Dist_UV__effect), and applied spread_half_pixel to the uniforms to improve font sharpness. These changes enhance rendering accuracy, reduce support issues related to text layout, and lay groundwork for future typography enhancements.
