RISC OS Open Ltd 于 2006 年 6 月 20 日成立 [1]，至今已走过二十个年头。这个项目成功地将一个专有操作系统转变为开源平台，并通过社区贡献实现了持续演进 [1]。
2013 年，RISC OS 被移植到 Raspberry Pi 上 [1]，为新一代用户打开了接触这一系统的大门。2014 年，项目代码库迁移至公开的 GitLab 平台，其中包含超过 106,000 个提交记录 [1]。2018 年，该项目在 Apache 2.0 许可证下完成重新授权 [1]。截至 2024 至 2025 年期间，RISC OS 接收了超过 1000 个合并请求 [1]。在第二十个年头（2025 至 2026 年），项目突破了 8GB Raspberry Pi 上的 32 位架构限制 [1]。
当前，RISC OS 正在推进"Moonshots"计划，其目标是将系统升级至 64 位 Arm 架构 [1]。
RISC OS Open Ltd marked two decades since its establishment on June 20, 2006, transforming a proprietary operating system into a community-driven open-source project [1]. The milestone comes as the initiative continues to expand its hardware support and release stable versions, with the 2013 port to Raspberry Pi introducing the system to a new generation of users [1].
The project has achieved significant technical milestones over its two-decade run. The codebase transitioned to public GitLab in 2014, preserving over 106,000 commits of development history [1], while the system was relicensed under the Apache 2.0 license in 2018 [1]. During the 2024-25 period alone, the project received over 1,000 merge requests from contributors [1]. Most recently, in Year 20 (2025-26), the team overcame the 32-bit limitation on 8GB Raspberry Pi devices [1]. Looking forward, RISC OS is pursuing its "Moonshots" initiative to upgrade the system to 64-bit ARM architecture [1].
