Instapaper 3.0.2 has hit the app store. This is the first version of Instapaper to support x-callback-url. Marco Arment, the developer behind Instapaper, was important to the formation of the ideas in x-callback-url, and we’re excited to see this version hit the store.
Instapaper’s integration with Terminology also represents the first “in-the-wild” use of x-callback-url’s two way callback support. If you select to lookup a word in Terminology from Instapaper, you are provided an easy way to jump right back to where your were. See Marco’s post for details.
