I have noticed since the upgrade to Roon 1.5 that it is taking a bit longer for new music files to be loaded to Roon or amendments of current files to be reflected in Roon. This may, of course, have nothing to do with the upgrade but due to such things as the number of tracks I have has reached some critical point (around 95,000 classical music tracks and 3,400 albums). Updating used to be almost instantaneous. This is not a major issue but the almost instantaneous updating was a very nice feature which meant that I could upload albums and/or correct metadata on the fly, before doing a backup copy.
