certainly, in terms of the engineering of the tree itself (names
change, things move, things get better, certain vestigial features are
trimmed), but i'm speaking in slightly more gross terms.

i always believed that, as far as support for devices goes, the
current "trunk" (from which all releases are grown) contains support
for all the stuff that any release ever contained, whereas current has
support in it for things that no release (yet) has supported.  that,
to me at least, makes current a proper superset of the release, or
conversely, the release a proper subset of the "trunk".  no?

je ne sais pas.  :(
