Oracle has published its latest quarterly update to GraalVM, the open-source Java JVM/JDK implemented in Java that also supports other execution modes and programming languages from Python to R to Ruby.

Given last month's release of Java 17 / OpenJDK 17, GraalVM 21.3 has added Java 17 support. Plus there are many other improvements to its various language front-ends and other components. Some of the GraalVM 21.3 highlights include:

- Java 17 support with GraalVM builds based on Oracle Java 17 and OpenJDK 17. OpenJDK 11 also continues to be supported while OpenJDK 8 is no longer supported by GraalVM.

- New optimizations and other improvements for the Native Image support.

- GraalVM's JavaScript support has implemented the proposals around Error Cause and Import Assertions. The JavaScript code has also expanded on its WebAssembly completeness.

- The Ruby support now has TRegex enabled by default for much faster matching of regular expressions. The Ruby code also has fully integrated support for foreign object traits.

- More of the core Python language support has been intrinsified and optimized for faster start-up and smaller footprint. There is also now a binary-compatible back-end for HPy 0.0.3, support for the Python multiprocessing module, support for the ctypes module, and other additions.

- The LLVM Runtime has been re-based to LLVM toolchain version 12.0.1.

- Various compiler optimizations and other performance tuning limited to GraalVM Enterprise, including better SIMD vectorization out of sequential code.
