Thanks for clarifying!


So, in anticipation of push back, I also want to provide some stats. I
looked at overall traffic since Jul 1, 2018 to yesterday. Traffic to any
of the release notes in general was a very small chunk of it (< 0.5%).

When just looking at the subset of release notes, the top 5 receivers were:

1. 11.0
2. 10.5
3. 10.4
4. "current/static/release.html"
5. 9.6 release index

This constituted a little over 35% of the overall release note traffic.

My inferences are that people tend to go to the release notes for the
"latest" release.

Now, in terms of things like "/docs/9.5/9-4-19.html" and the like, the
only one that had significant traffic was
/docs/9.6/static/release-9-5.html, and that was #25 on the list (the
notes coming before it accounting for 60%+ of the traffic). In fact, I
did not see another of the "mismatch" URLs until #37 on the list, which
was /docs/10/static/release-9-5.html

From a user experience perspective, does it stink that we're potentially
creating a bunch of 404s? Yes. Is it going to upset some people? Yes,
and I'm sympathetic to that. However, looking at the overall numbers, I
think we'll be ok, even if we don't have the redirects per Magnus'
suggestion downthread (which I will also reply to).

Correct.

Thanks,
