さらに見る New in this Update:
- When Artwork Display setting is set to "Full Screen", higher resolution streaming artwork is cached for better quality full screen appearance.
- Artwork Reuse Model: Single Artwork file is now shared amongst tracks within the same album, so long as the media server reports they have the same artwork. This helps conserve bandwidth when streaming multiple tracks from the same album, and WatchAmp will now also reuse local artwork from cached or downloaded tracks for streaming tracks of the same album when available.
- Siri Announce Notifications now pause and resume audio rather than just lowering the volume.
- When viewing chapter list for an M4B audiobook, list now scrolls immediately to active chapter.
- Added additional hardening for successful track download verification.
Fixes in this Update:
- When using an Apple Watch that does not support Always On display, or when Always On Display was turned off and the screen went dark, watchOS could suspend playback between tracks. Audio would resume only when the watch was raised/activated. Updated enqueue method should allow watchOS to continue playback while screen is off.
- Fixed seeking unavailable on first start streaming tracks
- Fixed seeking bug that could cause audio to seeking when the display is covered.
- Tweaked Play Next/Later queue handling, cache prioritization, and Headphone Disconnect/Reconnect recovery
4.1.0 9月26日
Fixes in this update:

- WatchAmp background downloads queue persistence is no longer suspended immediately when lowering wrist or exiting to clock. watchOS will still suspend large queues over time, but queues will resume when WatchAmp is reopened and more tracks will download when WatchAmp is backgrounded than before. For large download queues, it is recommended to keep WatchAmp in focus and the screen on.
