Hi, the EBook (The Big List HTML5 Edition) is still the current edition. If you purchase through the Scirra store, you can download updates from the store as they come available. If you purchase from my website, updates go out by email. I generally try to update it monthly. I hope to have a new update out by the end of the week. I haven't had an opportunity to finish the listing on the Scirra store for the Full Edition yet.
The Full Edition has a lot more resources, including a complete list of all app stores.
You can check it out here on my website http://neoprofessor.com/?page_id=55. There is a comparison chart, so you can see the difference between editions.
Hope this helps. Have any more questions, just drop me an email or PM, I'll be happy to answer them.
