RISC-V Officially Supported by CPython as Tier-2 Architecture in Milestone 3.15 Release

In a landmark milestone for open-source instruction set architectures (ISAs), the Python Steering Council has officially upgraded 64-bit RISC-V (rv64g) to Tier-2 supported status in CPython.

Tier-2 status mandates that CPython buildbots run full test suites on physical RISC-V hardware for every commit. Core developers guarantee that regressions targeting RISC-V architecture will block upstream patch merges, ensuring top-tier stability for edge computing and custom silicon developers.

Runtime engineers note that official CPython backing will accelerate RISC-V adoption across industrial IoT, automotive control systems, and specialized AI accelerator platforms.
