Talked to Scott James Remnant today, and asked him about the bug with atom.xml parsing and \<br/> elements; he pointed me at his arch tree and told me to update from there, which I've done.
Net effect, a tiny bump and all of a sudden atom.xml feeds are looking dead sexy. Anybody who's currently blogging on blogspot - your feeds should no longer look like crap! There was a small bug for a minute with the old template, where the (feed) links in the sidebar on the right were all pointing back to planetKDE.org instead of pointing to the actual RSS feed from the developer. That's been fixed.
If you notice any other issues, please let me know!
