+- New setting, Playback → Music Screen When Idle: against burn-in (the default) dims the music screen after 10 minutes without a key or touch and shifts it a few pixels every minute; screen off blacks it out after 2 minutes while the music plays on. While lyrics are showing it stays as it is. Any key, touch or new cast wakes it, and media keys keep working.
+- Where castbay.weenas.com can't be reached (common in mainland China), the update check, problem reports and usage statistics go through a relay, cast.weenas.com, instead of failing; the [privacy policy](/privacy) describes it.
+- An update found on GitHub, when the website can't be reached, now comes with its release notes (What's New).
+- Problem reports always include CastBay's own recent log and the AirPlay protocol's, even on devices whose system log leaves apps out.
