-# TypeType 1.7.3
+# TypeType 1.8.0
 
-TypeType 1.7.3 fixes BiliBili videos that failed during stream extraction after a metadata format change.
+TypeType 1.8.0 improves playback reliability, the watch experience,
+account portability, sharing and localization.
 
 ## Playback
 
-- Update PipePipeExtractor to the BiliBili metadata fix used by TypeType-Server.
-- Restore BiliBili stream extraction and preserve the available audio and video formats.
-- Update TypeType-Server to `1.7.2`. [PR #83](https://github.com/TypeType-Video/TypeType-Server/pull/83)
+- Recover stalled SABR segment requests instead of leaving playback stuck.
+- Preserve the exact playback position across WebKit provider changes.
+- Isolate WebKit seeks to prevent stale media state.
+- Improve paused Firefox seeks by filling the playback buffer first.
+- Synchronize compact player controls after seeking.
+- Reduce playback regressions when switching or recovering media sources.
+- Update TypeType-Player to MSE `0.1.59`.
+- Keep BiliBili stream extraction compatible with the fixes introduced in 1.7.3.
 
-No frontend change, configuration change or manual database migration is required.
+## Floating Watch Player
+
+- Keep the current video visible while scrolling through the page.
+- Add a draggable floating player.
+- Persist the floating player position and state across navigation.
+- Keep the compact player usable on mobile.
+- Disable the floating player in landscape layouts where it would obstruct content.
+- Keep the player stable when related videos are displayed.
+
+## Sharing
+
+- Add a compact share menu anchored to the share button.
+- Show the destination name next to each share icon.
+- Add direct links to the original provider.
+- Normalize YouTube Shorts share links.
+- Improve the share menu layout on desktop and mobile.
+
+## Playback Progress
+
+- Show playback progress directly on video cards.
+- Add batch progress lookup for faster history and recommendation loading.
+- Keep progress updates non-blocking during playback.
+
+## Volume Controls
+
+- Support mouse-wheel volume changes on every player layout.
+- Prevent the page from scrolling when the wheel is used over the volume slider.
+- Keep volume controls usable in the compact and floating players.
+
+## Localization
+
+- Add the German interface locale.
+- Add the German translation catalog.
+- Improve layout behavior for longer translated labels.
+- Make video settings responsive to the active locale.
+- Continue rejecting untranslated frontend messages during validation.
+
+## Account Portability
+
+- Support large YouTube Takeout archives.
+- Add ZIP64 archive reading for large imports.
+- Return a typed error when an upload is too large.
+- Preserve bounded import processing and progress reporting.
+
+## YouTube Login
+
+- Fix remote YouTube login completion after passkey or 2FA.
+- Stabilize remote YouTube input handling.
+- Improve diagnostics for failed remote-login sessions.
+
+## Server Reliability
+
+- Isolate the Server SABR contract behind explicit adapter boundaries.
+- Expand SABR contract and playback recovery tests.
+- Preserve bounded retries, playback generations and session isolation.
+
+No configuration change or manual database migration is required for this release.
