JRuby in 2017: Rails 5, Ruby 2.4, Performance
We'll survey the work going on to make JRuby more compatible and faster in 2017
JRuby has been compatible with various Ruby versions during its lifespan, ranging from the 1.6 series through today's 2.4. JRuby has supported Rails in some capacity since the 1.0 days. And at the same time, we've continued to improve performance. In this talk we'll explore JRuby's level of compatibility today and discuss the challenges of keeping up with an actively-developed language and ecosystem.
