Java 25 – Better Language, Better APIs, Better Runtime
by Nicolai Parlog
Java 25 is the next release with long-term support and a lot has happened since the last one:

• from unnamed patterns and flexible constructors to module imports
• from the foreign-function and memory API to stream gatherers and the class-file API
• from a simpler `main` to launching multi-source-file programs
• from Markdown in JavaDoc to quantum-resistend encryption
• from faster launch times to improved garbage collection

There are plenty of features in the language, API, and runtime to discuss - whether new, improved, or finalized. So let's go over them!

We’re looking forward to another great evening of learning, sharing, and community.

See you on September 10th! 👋
