The Rails Gravatar Plugin has undergone a bunch of changes recently. Highlights for this 0.0.2 relase are as follows.
- It is now bundled into a gem hosted over on Gemcutter. (Still works as a plugin also)
- Support for pulling Gravatars off of a secure https server was added.
- Support for using Gravatar ratings was added.
- Support for specifying a file extension was added.
All the old and new features and usage is well documented in the projects README.
