The Ruby committers have again continued their annual holiday tradition of gifting us a new Ruby version: Ruby 2.6 was released today, including the long awaited Just-In-Time (JIT) compiler that the Ruby team has been working on for more than a year.

Just-In-Time compilation requires Ruby to spin up a compiler process on startup, and we're proud to say that this feature is supported today on Heroku thanks to the diligent efforts of our very own Richard Schneeman. We'd also like to thank fellow Herokai Nobuyoshi Nakada for his effort making sure the new JIT works well with all of the officially supported compilers: GCC, Clang and Microsoft Visual C++.

Using Ruby 2.6 on Heroku

Rubyconf is upon us, and most of engineering team will be present in Orlando this week.

If you’re attending, or maybe just nearby, this would be a great opportunity to say hi and/or ask those burning questions you’ve got about Heroku. Whether you’re wondering if Heroku will be a good fit for your needs, or have questions about a currently hosted app, we’re happy to make time for you. Just email us here and we’ll find a time/place to talk.

Last but not least, don’t forget to catch Adam and Blake presenting on Lighweight Web Services with Sinatra and Restclient on Friday at 1:15pm.

See you there!
