As per [their blog post of the 27th April](https://blog.readthedocs.com/securing-subdomains/) ‘Securing subdomains’:
> Starting today, Read the Docs will start hosting projects from subdomains on the domain readthedocs.io, instead of on readthedocs.org. This change addresses some security concerns around site cookies while hosting user generated data on the same domain as our dashboard.
Test Plan: Manually visited all the links I’ve modified.
The docs currently show passing a package's hash(es) in the form of
``--hash:sha256=...``. When trying to install something using this
format, pip fails with the error ``pip: error: no such option:
--hash:sha256``. This should be changed to match the output of ``pip
hash``.
We don't need to talk about the network, since HTTPS should ensure transmission integrity. We do need to watch out for the CA chain. Stop mentioning the CDN because it's a deep hole: we might as well mention Rackspace and Amazon and who knows who else.
packages". With pip's index caching, and wheel caching, the motivation
to find a way to speed up pip is not as pressing anymore, although it is
still true that people may need a local-only install for certain cases.
This adds constraints files. Like requirements files constraints files
control what version of a package is installed, but unlike
requirements files this doesn't itself choose to install the package.
This allows things that aren't explicitly desired to be constrained if
and only if they are installed.
With wheel autobuilding in place a release blocker is some granular
way to opt-out of wheels for known-bad packages. This patch introduces
two new options: --no-binary and --only-binary to control what
archives we are willing to use on both a global and per-package basis.
