Java 27 Launch Stream

Java 27 was released on September 15th 2026! We celebrated that on the Java YouTube channel, where we hosted a 3-hour live stream covering the launch of Java 27, and the platform changes, as well as the latest developments at the intersection of Java and AI. Special guests from the JDK team and community shared what they have been working on and what they are looking forward to in JDK 27.
