MRI is excellent, but it is not the only option, and for two very specific workloads it is not the fastest one either. Meanwhile the two alternative runtimes have both shipped major releases in the last month: <strong>JRuby 10.1.2.0</strong> on 2026-09-21 and <strong>TruffleRuby 40.0.0</strong> on 2026-09-17.</p>
