Well, it takes you to the exact snapshot of the page of your 
selected version:

https://github.com/dlang/docarchives.dlang.io

That's why if you select anything before 2.079 at the spec pages, 
it won't even show the version chooser as it was introduced a bit 
before the 2.079 release (the Phobos documentation has had the 
button for a bit longer).

We can probably fix this by injecting a bit of custom JavaScript 
in the old snapshots that detects the current version and adds a 
"correct" version chooser button, but it's not on my priority 
list and no one else has bothered/cared enough about it either.
