This update fixes a crash in the Album Browser that could happen when using keyboard navigation together with Random sort. For Linux and Docker users, we addressed an issue where in-container upgrades could fail on some hosts with more restrictive file permissions. We also fixed an edge case involving the library-level import date setting, where streaming service content could appear in the wrong order after a sync when import dates were configured to use modification dates, and minor focus bugs in ARC. As always, thanks to everyone who reported these issues and helped us track them down.
