and SPARC64. In July 2010, version 8.0 (codenamed "Phoenix") was released. In April 2021, version 21.4 was released. In July 2022, version 22.6 was released. In April 2024, version 24.5 was released. In June 2024, version 24.6 was released shipping Wine for Windows application compatibility as well as LibreOffice and Thunderbird for a complete Linux desktop experience. In July 2024, version 24.8 was released shipping OpenJDK for Java compatibility as well as a multi-architectural MIPS64 Linux kernel built for SGI IP27, IP30, IP32 (r5k & r10k) as the first Linux OS release to boot on multiple SGI RISC workstations and servers. In December 2024, version 24.12 was released with initial support for running on Nintendo Wii U, improved SPARC64 and IA-64 stability, an improved global t2 package manager frontend and various other improvements. In April 2025, version 25.4 was released with worlds-first demonstrating AMD's ROCm HPC/AI stack running on RISCV and ARM64.
