The JDK 19 feature set is currently frozen, and Java 19 is expected to be officially released in September of this year. Take a look at these 7 new frozen features of JDK 19.
Record Patterns (Preview) Enhance the Java programming language to deconstruct record values with Record Patterns, which can nest record patterns and type patterns to enable powerful, declarative, and composable forms of data navigation and processing.
This is a preview language feature.
Java 19 Officially released on September 20, 2022, Java 19 is not a long term support release until March 2023 when it will be replaced by JDK 20, this update brings a total of 7 new features.
The update brings seven new features. ➜ bin . /java -version openjdk version "19" 2022-09-20 OpenJDK Runtime Environment (build 19+36-2238) OpenJDK 64-Bit Server VM (build 19+36-2238, mixed mode, sharing) OpenJDK Java 19 download: https://jdk.
JDK 19 / Java 19 Official GA JDK 19 / Java 19 has been officially released.
The new release contains a total of 7 new JEPs.

Java 19 was officially released a few minutes ago, a non-LTS (long term support) release with seven features including structured concurrency, record mode, a preview of external functions and memory APIs, and support for the open source Linux/RISC-V instruction set architecture (ISA).

JDK 18/Java 18 was released last month, and JDK 19 is scheduled to be released in September this year, so before many developers can use Java 18, two of the latest target features about Java 19 have been revealed.
There are two official features that will be released in the next version. One is the Vector API, and the other is the porting of the JDK to RISC-V. The former Vector API is an API that expresses vector computation and will be incubated for the fourth time in the next Java release; the latter proposed feature is the porting of the JDK to the open source Linux/RISC-V instruction set architecture (ISA).
Introduction From the Overview page of JDK 19, it appears that JDK 19 is in the Rampdown Phase Two, the entire feature set has been frozen and no further changes will be made to the JEP.
Java 19 has only 7 new features.
