Thanks very much for this, but what has happened to the packages for the 
Mouse Genome 430 2.0 Array (aka "mouse4302" or "moe430_2"), which seem to 
have disappeared altogether?

Now that the MetaData packages have forked into release and developmental 
versions, can you say a few words about this distinction will work? I 
understand that the developmental versions will be built for the 
developmental version of R, at least once R-devel is into alpha and beta 
versions. Is it the intention that the packages in the release MetaData 
repository will, in future, be aligned with the current Bioconductor 
release, i.e., the packages will be frozen at the time of the official 
release and that the release MetaData packages will change only once every 
six months? Or will they be updated more often, as at present, and simply 
built for the same version of R as the current Bioconductor release? Will 
there be a fixed length cycle for the MetaData developmental packages as 
for the functional packages?
