Deprecated APIs
===============

On developing Sphinx, we are always careful to the compatibility of our APIs.
But, sometimes, the change of interface are needed for some reasons.  In such
cases, we've marked them as deprecated. And they are kept during the two
major versions (for more details, please see :ref:`deprecation-policy`).

The following is a list of deprecated interfaces.
