This looks promising for the future of Ruby.

Meet Ruby Next, the first transpiler for Ruby that allows you to use the latest language features, including the experimental ones, today—without the stress of a project-wide version upgrade. Read the story behind the gem, discover its inner workings, and see how it can help in pushing Ruby into the future.

Discover the lesser-known parts of the next major framework upgrade, appealing to mature applications that have been around for a while. Instead of focusing on “greatest hits,” we will walk you through B-sides and rarities that make this new release enjoyable in subtler ways.

What B-sides and rarities are Vladimir speaking of?

While the most-advertised Rails 6 features like Action Mailbox and Action Text steal all the spotlight, it is unlikely that a real-life Rails application that has been around for a while will benefit from the ease of building WYSIWYG text editors right after the upgrade.

At the same time, less flashy features like multiple databases support or parallel testing can bring immediate gains to your productivity—and Rails 6 has enough of those to offer if you know where to look.
