LMS and iTunes 12.1 64 bit

I'm using a Windows 7 PC with iTunes installed, opening a library file and music saved on my Synology 213air.

I sync my iTunes library with Logitech Media Server on the Synology, so I can access all my music on my 3 Squeezeboxes around the house - does anyone know yet if the 64bit iTunes upgrade will affect LMS's syncing with my iTunes library? Should I hold off on upgrading iTunes?

I also use iTunesexport (http://www.ericdaugherty.com/dev/itunesexport/) to export my iTunes playlist to access and play on my Android mobile using DS Audio. Anyone know if Itunesexport will still work if I upgrade iTunes to 12.1 with 64bit? Don't want to upgrade it if I can no longer get my playlists into my phone. Does the 64bit upgrade change the nature of the library files, or just affect the way Windows runs the iTunes application?

Thanks

Andy
