ReactOS turns 30, marking three decades of open-source Windows reimplementation with active work on test suite overhaul, WDDM support, and a new full-time hire.
Key Takeaways
ReactOS celebrates 30 years since first commit; many current contributors were not born when the project started.
Carl Bialorucki hired full-time by ReactOS Deutschland e.V. (May 2025) to fix the long-neglected test suite, which mixed custom and Wine-derived tests only validated against Windows Server 2003.
Test suite cleanup involves untangling heavily modified Wine tests with poor change documentation and updating validation targets beyond Server 2003.
WDDM investigation signals a push toward Vista-era and newer hardware support, a shift in project priorities in recent years.
ReactOS 0.4.15 shipped in March 2025 after the previous release manager stepped down, with Bialorucki stepping in to lead the release.
