Constrain blurb to version 1.1 or older

[AA-Turner]

Rebuilding 3.5, 3.6, and 3.7 fail with the following error. Try constraining them to a previous version of blurb.

Do we need to rebuilt EOL versions at all?

Do we need to rebuilt EOL versions at all?

It's always a good idea to be able to do so:

• To add the EOL banner (once).
• To update the sidebar maybe.
• To update any other thing that we would need to update like meta tags, or I don't know.

Let's continue in #298.
