On this page, http://www.typosphere.org/trac/wiki/NewInTheTrunk, it says
a
new feature in the trunk is per category feeds. Is true, and if so, how
do
I use it?
Go the the category view page in your browser. Then either subscribe to
that page in your feed reader (if it supports RSS/Atom auto-discovery)
or
look at the page source (in the tag near the top) to get the feed
URL.
Every reader that I’ve used in recent memory supports autodiscovery, so
I
haven’t felt all that motivated to add a visual feed link.
