Everything you need to know about Rails 4.0

updated over 7 years ago; latest suggestion over 7 years ago

This proposal has been withdrawn...

An overview of the upcoming release of Rails, including:

  • New features
  • Deprecations
  • Security improvements
  • Upgrade gotchas

I'll try and cover all of the big things and some of the more interesting small changes as well as tips for upgrading existing 3.2.x apps

    I think Steven makes a good point. Instead of covering everything we need to know, maybe you could do a deep dive on a single topic?

    With the hoo-ha about params last year and the recent patch fever it feels like security would be a good choice. I know strong parameters are coming, but are there other things that will make my app more secure by default? If not, are there things I should be switching on (or off), or approaches I should be taking that Rails 4 makes easy (or hard)?

    What can we get out of this which we couldn't get out of a blog post?
