Just spotted this — thanks for the heads up, it’s now fixed.
Hi Sellingr,
I just updated the plugin to support WordPress 2.6. Download version 0.2 of Feed Wrangler and give it a go.
Have you tried get_the_excerpt() ?
I also needed to create custom feeds and this post came quite in handy.
I just added a plugin that might be relevant to those tackling the same problem, which might make custom feed creation a bit easier:
