33247	PDF documentation build broken	AndrewN	AndrewN	"https://readthedocs.org/projects/django/builds/ shows that PDF builds of the docs are failing.

The error message in a log from a recent build:

{{{

}}}

The [https://buildmedia.readthedocs.org/media/pdf/django/latest/django.pdf last generated PDF] has a date of September 27 and on that date in 5bac1719a2fcb “Refs #32355 -- Used @functools.lru_cache as a straight decorator”, `lru_cache()` was changed to `lru_cache` on that line.

I believe the issue is that readthedocs is currently using a too-old version of python for the documentation build."	Bug	closed	Documentation	3.2	Normal	fixed			Accepted	1	0	0	0	0	0
