This is an additional security hardening step, to make Zulip default
to preventing SSRF attacks. The overhead of running Smokescreen is
minimal, and there is no reason to force deployments to take
additional steps in order to secure themselves against SSRF attacks.
Deployments which already have a different external proxy configured
will not gain a local Smokescreen installation, and running without
Smokescreen is supported by explicitly unsetting the `host` or `port`
values in `/etc/zulip/zulip.conf`.
Previously, our docs had links to various versions of the Django docs,
eg https://docs.djangoproject.com/en/1.10/topics/migrations/ and
https://docs.djangoproject.com/en/2.0/ref/signals/#post-save, opening
a link to a doc with an outdated Django version would show a warning
"This document is for an insecure version of Django that is no longer
supported. Please upgrade to a newer release!".
This commit uses a search with the regex
"docs.djangoproject.com/en/([0-9].[0-9]*)/" and replaces all matches
inside the /docs/ folder with "docs.djangoproject.com/en/3.2/".
All the new links in this commit have been generated by the above
replace and each link has then been manually checked to ensure that
(1) the page still exists and has not been moved to a new location
(and it has been found that no page has been moved like this), (2)
that the anchor that we're linking to has not been changed (and it has
been found that this happened once, for https://docs.djangoproject.com
/en/1.8/ref/django-admin/#runserver-port-or-address-port, where
/#runserver-port-or-address-port was changed to /#runserver).
The links we have now redirect to "My groups" and not to our
Google group. Also, the RSS feed is no longer supported by Google,
so we should no longer link to it.
Fixes#19560.
Thumbor and tc-aws have been dragging their feet on Python 3 support
for years, and even the alphas and unofficial forks we’ve been running
don’t seem to be maintained anymore. Depending on these projects is
no longer viable for us.

This new pages accomplishes several interrelated things:
* Documents that Zulip Cloud runs master and how that works.
* Documents policies on how long client apps are expected to support
old releases in our compatibility matrix.
* Removes the 3-years-stale roadmap article.
* Provides a central place to talk about different versions in Zulip.
* Provides a better place to link to from our "you need to upgrade" nag.
This content is not intended to be final, but should be finalized in
the next week or so.
Fixes#18322.
This likely still needs work on updating the list of highlights, as
well as an editing pass, but we shouldn't need to read the whole
`git log --stat` again.
