Sort Order change from updated 8.1 compared with new install 8.2

[Peter@57m]

Ok I have to say I am 99% sure of this change but I can't easily go back to make 100% sure.

I have a custom tag which I use to tag recent albums. Currently there are 77 albums in this list. Initially I updated MinimServer to 8.2 and the sort order when I reached the 77 albums was Artist, Album - this is set in tagOptions as Album.sortTags={Artist,Album}. This was the order prior to the update as well.

I had allowed it to do the update but had seen the comment "If you have 0.8.1 installed already, you can either do a full install of 0.8.2 or you can stay on 0.8.1 and apply the online updates. You will get a few additional fixes if you install 0.8.2 (see the Release notes for details)."

So I thought that when I had time I'd install the complete new version. I did that tonight and then noticed that the sort order of the albums in the Recent list was now Album. When I updated the QPKG on the QNAP it retained the properties that were already setup. I thought that the retention of the system config files may be causing the problem. So I deleted MinimServer from my QNAP and did a complete re-install and recreated the properties but still the 77 albums sort alphabetically by album rather than Artist, Album.

Did anything change here to cause this behaviour? Am I right in thinking the tagOptions of Album.sortTags should change the order

PS: I did also update Java to 8.0.1 before doing the 8.2 QPKG install
