November 2024 highlights: Delivered major UX improvements and reliability upgrades across ReVanced patches and the Revanced Manager. Key user-facing features include YouTube UX and compatibility updates (icon handling for YouTube 19.34+, API v4 announcements, and Shorts UI hiding) and Cross-App UX enhancements (screen capture restrictions removal, GMS Core support, TikTok/Twitch ad controls, and YouTube UI tweaks like alternative thumbnails and enhanced player controls). Behind the scenes, patch engine reliability was strengthened via patcher version bumps, increased heap size to mitigate OOMs, and dependency/patch fixes for Twitter and TikTok; fingerprinting and patch targeting were refined across multiple apps; and a Kids Playback fix was implemented for iOS/Android VR clients. Revanced Manager saw dependency upgrades, build system improvements, API v4 migration and URL handling refinements, and patch-performance optimizations using Set-based collections to avoid recomputation, all contributing to faster, more stable updates and broader compatibility.
