Broken link in PyMC3 docs
A Google search of "bayesian linear regression pymc" leads me to this old page, which has the handy link at the top:
Note
You are not reading the most recent version of this documentation. v4.1.3 is the latest version available.
Unfortunately this link looks broken. The correct link seems to be https://www.pymc.io/projects/docs/en/stable/learn/core_notebooks/GLM_linear.html.
Thanks @maresb. We have opened a related issue on this with #5996.
I am not sure there is anything we can do other than making the 404 page more friendly or informative. Very little pages have not been modified and restructured between v3 and v4, and the version switcher changes the version but not the rest of the url (which is what would be needed here).
The google search now leads to this issue, and the old page didn't show up for me at all..
Also, we have abandoned v3, so... wontfix
For me it looks like this:

The top PyMC3 link has the same issue as before, but at least the second link is now the correct one. Not perfect, but at least the correct page is now easily discoverable, so good enough. Thanks for closing!
