Moonfin v1.3.0 Release Notes

New Features

Added full localization framework with Flutter l10n support, enabling community-contributed translations across the entire app

Completely redesigned the book and audiobook library UI with a brand-new layout, added bookmarks and table of contents support to the book reader

Default audio language preference — set a preferred audio language in playback settings so tracks are selected automatically
Dolby Atmos labels — audio profile detection and display for Dolby Atmos metadata on item detail pages
Subtitle stroke/shadow support — added stroke and shadow rendering for subtitles in both video and live TV player screens

Window state persistence — window size and position are now saved and restored between sessions on desktop platforms

Seerr navigation icon is now hidden when no Seerr instance is configured via the Moonfin plugin, preventing a broken entry point in the toolbar and sidebar

The Windows (Inno Setup) installer now upgrades the existing installation in-place instead of creating a new side-by-side install each time

Audio too quiet / stereo downmix broken — refactored audio channel handling and volume management, increasing the max internal volume ceiling from 100 to 200 to resolve low audio on surround-sound content
Missing TV guide data — fixed EPG time window calculation that was not using UTC, causing guide data to appear missing for certain time zones; also improved the EPG grid to expand dynamically with screen size on desktop
Media bar 401 errors — resolved an issue where the media bar returned HTTP 401 after a user's library permissions were changed server-side
Seerr 400 errors on media requests — fixed Seerr returning HTTP 400 when requesting media
Seerr rows sync — fixed discover-row synchronization from the Moonfin plugin for Seerr/Jellyseerr
iOS brightness control — fixed missing screen_brightness_ios dependency that prevented brightness gestures from working on iOS
