Greetings, folks! If you haven’t been keeping up with the latest Rails news, we have a new version! Ruby on Rails 3.2.1 has recently been released with some very welcome changes!

• Faster development mode – Rails now only reloads the classes you’ve actually changed between requests in development mode.
• Explain queries – In development mode, you can automatically show the explain of certain queries by calling .explain at the end of your query. The results will go in your log.
• Active Record Store – Active Record now has a built in way to do key/value storage right from your models. No plug-ins or external gems required!

You can also check out the change log of all of the fixes and changes, both big and small. Enjoy!
