entries. Use :ref:`bytes <func-bytes>` and :ref:`bytearray <func-bytearray>`

automatically, the daily documentation builds now disable the default output

caching features in Sphinx.

The build process on Windows no longer depends on Subversion, instead

pulling external code from GitHub via a Python script. If Python 3.6 is not
|
|
found on the system (via ``py -3.6``), NuGet is used to download a copy of
|
|
32-bit Python.
