[vlc-devel] Which contrib for 1.1.2?

I may have missed something, but I didn't think a dated contrib was enough
to link it to a particuler VLC version. How does someone pick the correct
contrib? Is it simply looking at the date of the release and find the
contrib that has the latest date prior to the release date? I would have
though Jean-Baptiste might have already packaged contribs for a next release
while developement is ongoing. If it is always that the latest contrib is
for the latest VLC version, that's easy enough as far as I am concerned but
just need to know. Would it be something nice to add to the about box 'built
using contrb...' ?
