'New Music' doesnt' list new albums for me, aditonal question about new release updat

Hello,

Two short questions if I may:

i) When I add new albums/CD's to my music folder , for me they don't always seem to appear under 'New Music' for some reason following a rescan for new music. I can't find any specific setting that might effect this. Even if I perform a full rescan (manually) selected I get the same. Is there some suttle paraments taken from the content that determines it's presence or not. Or mereley the date it's added to the music folder. Can anybody throw any light on this please.

ii) The latest server update process now smatly downloads the latest version of the server software. Simply following the given install instruction appears to install without issue. But I note it doesn't appear to remove the existing instance of the program , but merely replaces the current installation. Learned Linux/Unix people tell always best to uninstall first. I trust the developers know exactly what their doing so I wonder why this is OK in this instance ?

Thanks as always for the support on this fantastic forum
