#Java19 is gonna be an amazing release 🤩 - the most break-through in a few years and probably for a few years to come. Here's why, from least to most groundbreaking feature (IMHO). 🧵 (If you want to follow up on something, the video description has tons of links.)

Vector API (4th incubator) Allowing reliable compilation to CPU vector instructions ("SIMD") is a great performance improvement for arithmetic-heavy code like image processing or machine learning. This API is mature, but needs to wait for Valhalla for final touches. 😕
Pattern Matching in Switch (3rd preview) Brings switch improvements, patterns, and sealed classes together, so we can finally use pattern matching. #Java19 doesn't finalize but makes progress (on null handling and case refinement) and I hope it's the last preview.
Foreign Function & Memory API (1st preview) After a few rounds of separate incubation, #Java19 moves foreign function and memory APIs into their final package for their first preview. They make handling off-JVM memory and code easier and faster - the rocky isthmus has been cut!
