A fast and easy way to add RSS and Atom feeds to your WordPress blog.
This is the official plugin from the SimplePie team. It relies on the SimplePie Core plugin, and includes several features:
The major changes in version 2.2 are reliance on the "SimplePie Core" WordPress plugin, cache location fixes, updates for WordPress 2.5, much more noticeable error messages when dependencies are missing, and support for a variety of new SimplePie 1.1 features such as setting a per-feed item limit when using Multifeeds.
The major new feature in version 2.1 was support for "post-processing", which allows you to write small PHP scripts to alter the output from a feed. Popular uses include stripping out everything from a feed item except for images, and adding a target attribute to links to make them open in new windows. We've also added better support for error handling and messages, and made the plugin more aware of it's location, enabling a simpler install process.
