The Go memory model has been revised to align with the memory model used by C, C++, Java, JavaScript, Rust and Swift. Most of the changes in Go 1.19 are related to the toolchain, runtime, and libraries. Red Hat Enterprise Linux 9.2 comes with an updated version of Go 1.19. Optimized APIs such as proc_macro::Span::source_text and Option::unzip. This helps disable optimizations when running the benchmarking of code or examining machine code that the compiler generates. Red Hat Enterprise Linux 9.2 comes with a stable version of Rust 1.66 with stabilized APIs and functions. Red Hat Enterprise Linux 9.2 offers an updated version of Rust 1.66, Go 1.19, and LLVM 15, enabling developers to modernize their applications with the latest toolsets and compilers. The latest versions of toolsets and compilers This makes a compelling case for the PostgreSQL 15 upgrade, as this is a significant performance improvement over past versions. PostgreSQL 15 yields a fourfold improvement in row sorting speed for on-disk and in-memory sorts. This new permission model constrains ordinary users to user-private schemas. PostgreSQL 15 has a more secure permission model in which create permission is revoked for all users except the database owner. PostgreSQL 15 is the latest version of a popular open source database in Red Hat Enterprise Linux 9.2. This helps applications communicate with their peers securely by ensuring the client and server are using the most secure protocol available. Red Hat Enterprise Linux 9.2 also supports Application-Layer Protocol Negotiation (ALPN) as part of the Nginx 1.22 update. Nginx 1.22 is the latest version of the Nginx lightweight web server, which brings new capabilities, such as OpenSSL 3.0 compatibility, hardening against request smuggling, and cross-protocol attacks. Speed improvements from previous Python versions range from 10% to 50%, enhancing overall system performance. 
This feature optimizes operations, enabling code to run faster. This version includes the critical feature of Specializing Adaptive Interpreters. Python 3.11 is the latest version of the Python programming language.Many of the popular languages in web development and enterprise applications have been upgraded in Red Hat Enterprise Linux 9.2 such as: In this article, you will learn what's new in RHEL 9.2 and how it improves the developer experience. You can download RHEL 9.2 at no cost as part of the Red Hat Developer program subscription. Build, deploy, and manage applications and critical workloads faster and more efficiently with a consistent experience across physical, virtual, private, public cloud, and edge deployments. This release provides a flexible and stable foundation to support hybrid cloud innovations. Red Hat Enterprise Linux (RHEL) 9.2 is now Generally Available (GA).
