What's new

v9.9.1Sep 21, 2026

Advanced GPU Color Filters & Reader Enhancements** * Introduced GPU-accelerated sharpening modes and line-darkening color filters with dedicated controls. * Added database migration (v32 to v33) to persist granular sharpening and line-darkening settings. * Redesigned `ColorFilterConfigActivity` UI with multi-column landscape configurations and real-time preview processing. * Optimized image transformations by processing preview bitmaps safely in memory to prevent potential concurrency race conditions and main-thread corruption.
**Alternative Cover Art & Manga Management** * Added UI support for discovering, selecting, and managing alternative cover art from multiple sources (`AlternativeCoversActivity`). * Implemented manga unavailability handling, including detailed error dialogs, notification badges, and parameterized error states. * Introduced settings to toggle NSFW content visibility within launcher shortcuts. * Added "recently read manga" classification and tracking enhancements.
**Search, Filtering & System Logs** * Added source search filtering, screen-based query logging, and tracking structures (`TrackLogsDao`). * Updated URI intent filters for `kotatsu.app` navigation. * Cleaned up obsolete database query methods across Favourites and History DAOs.
Code Cleanups & Removals: * Inlined and purged obsolete image processors (`VibranceProcessor`, `SharpnessProcessor`). * Removed legacy dither/grain CPU filter options and related settings. * Cleaned up dead code, redundant helper classes, and unused UI utilities (including `SectionedSelectionController`, `BackupEntriesAdapter`, and unused primitive extensions). * Removed unused localization resources (French strings and plurals).
Merged changes from Kotatsu Redo upstream: • Fix crashes • Alternatives as now disabled sources option • Fix Atsu • Fix Batcave • Fix Readcomicsonline search • Better handling of Mangago chapter branches • Ninemanga fixes.
