Previously we listed both those as unsupported, which confused some users
particularly with new beta releases. While they are technically not supported
yet, it gave off the image that specific features would not be in newer
versions anymore, since they got listed as unsupported.
In passing, fix the style of the links in case they only exist in old
versions, which would put an extra | character in the version list.
This makes it possible to figure out when the docs were actually
loaded, since developer docs don't carry a version number. This is
actually going to be the docs *load* timestamp, and not build timestamp,
but they should be close enough together that it shouldn't matter.
Fixes#108
