Thanks to everyone involved in the beta-testing process, we have identified and fixed a number of bugs in the first beta of Rails 4.2.0. As we are moving further along into the release process, this is a great time to start testing it with your apps!
Also found in the same announcement blog post was the news that the legendary Yehuda Katz is retiring from the Rails core team. (Hint: It's a great time to send a thank you note on Twitter to express your gratutide.) Check out the core alumni page for a list of heroes who helped shape Rails into the framework we love today.
So far, I have been running this newsletter by myself. Unfortunately, as you might have noticed, I wasn't able to dedicate as much time to this newsletter as it deserves, especially when other tasks and travelling get in the way.
The Good News™? You can help! If you are interested in joining force to curate this newsletter, keeping our 1000+ readers in the loop about the latest development in Rails, please drop me a line!
(Special thanks to the Goodbits team for working on the new collebration features that makes this possible!)
In addition to fixtures, tag rendering is also getting a little bit of a speed boost. As noted in the pull request, the tag helpers in Rails used to sort the HTML attributes alphabetically, which turned out to be unnecessary.
If you making assertions on their output in your tests, you should switch over to the assert_dom_equal-family helpers.
You might not be aware of this, but defining callbacks (e.g. after_create) before the associations (e.g. has_many :comments) might result in undesirable side-effects. There are plans to improve this situation though, you can follow this ticket for progress.
Due to an upstream change in Rack, the default value for the -b (the bind address) option in rails server has changed from 0.0.0.0 (listen on all interfaces) to localhsot (listen on the loopback interface only), which means that, the development server can only be accessed from your own computer by default.
And that's it for this issue of This week month in Rails. As always, there are a lot more changes on Rails than what I can cover in this newsletter, so I encourage you to check them out yourself!
