I found the following bugs.
No. 1: 'Play next' no longer works from the discography view. An album, single or EP will be placed at the end of the queue.
No. 2: The sorting of the discography view cannot be permanently changed. Each time the discography is opened, the sorting is back to 'Type'. This bug exists since Beta 8.46. With the official version 8.45.0.2, the desired sorting is saved permanently.
