I've released an update to the DualFeeds plugin (which allows you to offer BOTH Full Post AND Summary feeds, so your readers can choose the format which suits them best).
The update only contains minor changes, including:
1. Added alt attribute to the image tags for better accessibility / validation.
2. Making the subscribe.png image 170px wide instead of 180px, so that it doesn’t break narrow sidebars.
3. Removing an extra space from the autodiscovery link for the Comments feed.
For more details on the changes see the release announcement.
