As per their email ‘Changes to project 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. One was not modified - `http://media.readthedocs.org/epub/pytest/latest/pytest.epub` - since it doesn't work on `readthedocs.io`.
While this leads to slightly more complicated user code for the common
case (checking if the exception is of a given type) it's easier to
implement and more flexible.
When __tracebackhide__ gets set to an exception type or list/tuple of
exception types, only those exceptions get filtered, while the full
traceback is shown if another exception (e.g. a bug in a assertion
helper) happens.
Since 'py.test --help' shows --full-trace as an option (and not --fulltrace)
even though both forms are accepted I assume --full-trace is the preferred form
and should therefore be used in the documentation.
