[CentOS] centos' current release versions?

hi,
what is the current release versions for centos? it seems to a trivial
question although:
- centos/3 -> 3.4 why not to 3.5?
- centos/4 -> 4.0 why not to 4.1?
on the other hand
# rpm -q centos-release
centos-release-4-1.2
why not centos-release-4.1-2? in the current case we can't write in
yum's repo file we can't write:
.../centos/$releasever/os/$basearch/
since $releasever is 4 and not 4.1 (or 4.0) so we have to lean on the
symlink which currently point to an older version. but even if it's
point to the right version imho it'd be better if $releasever should be
4.1 rather then 4.

just my 2c.
yours.
