Homepage|Build Repository: Removed static packages for 1.9.7—1.9.9

Now that the 1.9 series has ended the index should only feature the
last 1.9.10-1 release.

Ideally I'd like to factor this s"folding" into the user interface
itself rather than at the point of page generation (so that the user
can still drill down to the earlier releases, should they wish).

Once the build events are stored persistently, the repository index
can be reimplemented using AJAX methodologies (with each event served
up to the client as a JSON object graph).
