TL; DR: We spoke with JRuby Co-Lead Developer Charles Nutter on JRuby’s journey during the COVID-19 pandemic, the open-source community, and the implementation’s compatibility and performance. JRuby released its latest version, JRuby 9.4, in November 2022 to match compatibility for applications that run on Ruby 3.1. Although the JRuby team plans to augment performance this year, JRuby remains the fastest way to run most Rails applications and provides top-notch scalability for large workloads.
