Something has changed in one of the recent dev builds that seems to have broken my personal theme's use of %ss and %St.
I have a location and naming convention for the Playlists directory on each of my various iPods that allows me to cache a string that my theme can then retrieve and use to display as a label in the theme's status bar. This allows each iPod to have a unique label while keeping the theme code generic. So if my iPod is named iPod_1, I name the Playlists directory PlaylistsiPod_1 and place it in the iPod's root directory. When my theme goes to draw that iPod's name in the status bar, it retrieves the name string with
%ss(10,-,%St(playlist catalog directory))
which strips away "/Playlists" and leaves "iPod_1". Or I should say it used to do that. Yesterday when I updated one of my iPods to the latest dev build I found that the label getting drawn in the status bar is now tsiPod_1, presumably starting with the last two characters of "Playlists".
I suspect this has been caused by the change in fdc3668a6a 23rd Mar 14:37, where enumeration of mounted volumes has been added/changed.
[edit] More to the point, it would seem that every theme's prior use of %St(playlist catalog directory) will be affected.
