Upgrading to Rails 4
I read through a book named Upgrading to Rails 4. It's a must-read book for all the Rails users. You'll definitely face with upgrading your existing apps to Rails 4, so it's better for you to read it and get knowledge in advance.
The books gives us what we need to know about Rails4 from 3 aspects:
- Deprecations
- New Features
- Common upgrading scenarios
Even though many chapters to be left as "coming soon", it has been ready to be read, I think. I investigate Rails 4 for this slides, but now you don't need to do such labor. Just read this book.
