This is Prathamesh bringing you the changes from this week in Rails!
This week we had 22 awesome people making Rails better. We also had 3 people contributing for the first time.
Ruby 2.4 is coming! If you have already tried it with Rails 5, a key must be 32 bits error was raised due to a breaking change in Ruby 2.4 related to openssl cipher key lengths. It is now fixed, while keeping backward compatibility with any existing signed data. 🎉
Now we can download email attachments in mailer previews similar to real-world emails thanks to this change.
This change makes sure that the fixture_file_upload test helper works properly in integration tests. In case you missed it, integration tests are the default way of testing controllers in Rails 5.
Rails 5 introduced ApplicationJob as the default base class for Active Job classes. When testing these classes, the proper test adapter was not being invoked due to looking for subclasses of ActiveJob::Base instead of its descendants. This change fixes it.
Although I enjoyed reviewing all the commits from the last week, there were as usual too many to mention exhaustively. But do check them out yourself here! Until next week!
