How frequently are you referencing release notes from older versions --
and I don't mean ones that are just deprecated, but things like 8.2? Or
even minor versions such as 8.2.5?

Is there a way to keep a balance on the code side: keep the source files
in but don't reference them to be built? That may not help with the
tarball size, but would certainly still help build times + lower
HTML/PDF output.

We can set up some redirect rules for this in pgweb. We have a record of
what the latest version is, so we can intercept anything going to
`/current/release-(1?[0-9]+(\.[0-9]?` (untested regex) and point it to
the correct version.

The original thought process was to _not_ do that given the effort, but
if it's just for `/current/` it may not be so bad.
