July 2025: Implemented two critical reliability fixes in keiyoushi/extensions-source. 1) Poseidon Scans base URL migrated to https://poseidonscans.com with a version increment to reflect the change, ensuring content is sourced correctly. 2) Mangas-Origines chapters fetch reliability improved by adding an AJAX-based fallback when the primary selector fails, with a corresponding version bump. Together, these fixes reduce fetch failures, improve user experience, and strengthen release traceability through linked tickets.

April 2025: Core platform cleanup and feature expansion through Shadowtrad removal and Royal Manga Source integration, delivering reduced maintenance effort and expanded content reach. Shadowtrad extension was removed end-to-end, including build scripts, resources, and the main Kotlin source, with deprecated functionality eliminated from the codebase. Royal Manga Source was added with build configuration and integration, including selectors for popular manga, details, genres, author, and page lists, plus rate limiting for network requests to improve reliability and API usage compliance. These changes establish a cleaner codebase and set the stage for future source integrations and scalable content delivery.
