Red Hat Enterprise Linux 9 extends RHEL 8's module packaging features.These application streams, called rolling streams, are fully supported for the full life of RHEL 9. Application stream contents also include tools and applications that move very fast and are updated frequently. Developers can select from multiple versions of user-space components as application streams that are easy to update, providing greater flexibility to customize RHEL for their development environment.

Red Hat Enterprise Linux 9 improves the application streams experience by providing initial application stream versions that can be installed as RPM packages using the traditional yum install command.

With next-generation application streams, developers will have more choices when it comes to versions of popular languages and tools.

That gives developers a better handle on how their code performs. The new GCC compiler comes with modifications for C and C++ code compilation, along with new debugging messages for logs. The new features in the GCC compiler help users better track code flow, improve debugging options, and write optimized code for efficient hardware usage.

RHEL 9 ships with updated versions of core developer toolchains such as GCC (11.2.1), glibc (2.34), and binutils (2.35).

Red Hat Enterprise Linux 9 is built with a number of the latest runtimes and compilers, including GCC 11.2.1 and updated versions of LLVM (13.0.1), Rust (1.58.1), and Go (1.17.1), enabling developers to modernize their applications.

RHEL 9 can be downloaded for free as part of the Red Hat Developer program subscription. It can run your code efficiently whether deployed on physical infrastructure, in a virtual machine, or in containers built from Red Hat Universal Base Images (UBIs). This release is designed to meet the needs of the hybrid cloud environment, and is ready for you to develop and deploy from the edge to the cloud. Red Hat Enterprise Linux (RHEL) 9 is now generally available (GA).
