Bugs

 * The update process to this build has a chance of hanging for extended periods of time.
 * Live preview doesn't work for pinned site tabs on some machines, a gray window is seen instead of the intended content.
 * There's a chance of encountering an error with the error code 0x80070426 when using a Microsoft account to sign into certain apps. If this bug is encountered, it can be usually fixed by restarting the system.
 * The modern Disk Management page located at Settings → System → Storage → Manage Disks and Volumes in the Settings app is completely blank, and as a result it will not display any drives present on the system. To workaround this issue, use the legacy Disk Management tool to manage disk drives.
 * Some screens incorrectly have black text on dark backgrounds when using the dark theme.
