Oct 1, 2025

October 2025 across WordPress iOS/Android and Automattic Jetpack delivered a focused set of stability, performance, and UX improvements to the editor experience. Highlights include GutenbergKit dependency upgrades to latest stable builds on iOS and Android, a performance-oriented editor load warm-up and settings prefetch, a critical GutenbergKit memory-leak fix on iOS, relocation of editor theme styles to site settings aligning with web defaults, and Android UX enhancements (modal handling and UI feedback) plus a Pixel 6 Pro IME inset fix. These changes reduce first-load latency, improve reliability of editor/media flows, and establish cross-platform consistency with web-era defaults, ultimately supporting faster time-to-value for content creators and site editors.
