5 Years of Support + These Features? Java 25 is Unmissable
Java 25 dropped on September 16, 2025 — the first LTS release since Java 21. With 18 JEPs and 5+ years of premier support, it's the version every team should be planning to migrate to.
In this video I cut through the marketing and walk you through the features you'll actually use. No jargon, no fluff — just what changed, why it matters, and when to use it.
What you'll learn:
✅ Why JEP 512 is the biggest beginner-friendly change in years
✅ Module imports + flexible constructors — daily paper cuts, gone
✅ Scoped Values: the modern alternative to ThreadLocal
✅ The performance trio (JEPs 515, 519, 521) cutting startup & memory
✅ Preview features coming in Java 26+ (primitives in patterns, structured concurrency)
✅ A 30-second decision tree: should you upgrade?
