[pmwiki-users] pmwiki-2.1.beta14 released, improved RSS and Atom feeds

[DaveG]

Interesting to hear that they are very different. I didn't get that from 
the RssFeedDisplay which has
 >> add the line include_once("$FarmD/local/rssdisplay.php");
 >> or include_once("local/magpie/rss_fetch.inc"); to your local/config.php

I was actually looking to cache the RSS feed generated by pmWiki, and 
thought Magpie was the answer. Reading your comments, and thinking about 
it a little more, I see that caching the AllRecentChanges is pretty 
meaningless -- it's a pretty low hit already, so caching won't make much 
difference.

I'll add some text to the RssFeedDisplay to make the difference clearer.
