Happy Holidays from Heroku. Congratulations to the ruby-core team on a successful 2.3.0 release, which is now available on Heroku -- you can learn more about Ruby on Heroku at We had the pleasure of speaking with Matz (Yukihiro Matsumoto), the creator of Ruby and Chief Ruby Architect at Heroku, about the release.

What’s New in Ruby 2.3: Interview with Matz

Ruby releases happen every year on Christmas day. Why Christmas?

Ruby was originally my pet project, my side project. So releases usually happened during my holiday time. Now, it’s a tradition. It’s ruby-core’s gift to the Ruby community.

We're pleased to announce the beta of SSO for Heroku.

At the center of this, we built a new operations console to give ourselves a bird's eye view of the entire system, be able to drill down into issues in a particular space, and everything in between.

The operations console is a single-page React application with a reverse proxy on the backend to securely access data from a variety of sources. The console itself started off from a mashup...

A year and half ago, we launched support for PHP on Heroku, built from the ground up with modern features designed to give developers a more elegant and productive experience on the platform. Last week, we made PHP 7 available on top of a new, reworked version of our PHP support, and our users are adopting PHP 7’s exciting new features and stellar performance improvements quickly—we’re already seeing PHP 7 being used in the majority of PHP deploys on Heroku.

Under the hood, much of the logic that handles a deploy has changed, but not the fundamental principles upon which our support for PHP applications is designed. We've always been determined to provide a fully standards-based...
