It looks as though the information from refcounts.dat isn't making it into the online docs for 3.4 and 3.5.  See e.g., the documentation for PyList_GetItem.  For 3.3 [2], there's a "Return value: Borrowed reference." annotation supplied by Sphinx's refcounting extension.  For the 3.4 and 3.5 docs that annotation is missing.

Issue originally reported by Jianfeng Mao on the python-dev mailing list [1].

N.B.  When I build the docs locally on the default branch (using 'make html' from the Docs directory on a clean checkout), I *do* see the refcounting annotations in the html output.

New changeset 8c12d3e0f1de by Benjamin Peterson in branch '3.4':
fix ref count annotations on sphinx >= 1.2.1 (closes #21286)
