# Front Page Source: [https://reactos.org/](https://reactos.org/) ### Recent News ## [30 years of ReactOS](https://reactos.org/blogs/30yrs-of-ros/) Happy Birthday ReactOS\! Today marks 30 years since the first commit to the ReactOS source tree\. It’s been such a long journey that many of our contributors today, including myself, were not alive during this event\. Yet our mission to deliver “your favorite Windows apps and drivers in an open\-source environment you can trust” continues to bring people together\. Let’s take a brief look at some of the high and low points throughout our history\. ## [Progress update: fixing the ReactOS test suite](https://reactos.org/blogs/cbialorucki-tests-2/) For many years, the ReactOS test suite was neglected\. It was a random collection of our own tests and old Wine tests that were only checked against Windows Server 2003 and sometimes a random newer version of Windows up to the discretion of the contributor\. The Wine tests we imported were heavily modified and the changes made weren’t always well documented\. I’m here to clean up this mess\. I have been deeply involved with the ReactOS project since 2023 and in May of 2024 I became an official project developer\. ## [An initial investigation into WDDM on ReactOS](https://reactos.org/blogs/investigating-wddm/) The history of ReactOS spans a wider range than the lives of many of the people who work on it today\. Incredible individuals have come and gone from the project with vastly different goals for what they want to see developed\. In recent years, better hardware support has emerged as one of those goals\. As ReactOS gazes towards the world of Vista and beyond, a few questions about how hardware works emerge\. ## [Carl Bialorucki hired to improve ReactOS test suite](https://reactos.org/blogs/cbialorucki-tests/) Hi, my name is Carl J\. Bialorucki\. I started making a name for myself in the ReactOS community by contributing several shell improvements\. In May of 2024 I was added to the core development team and in March of 2025 I led the release of ReactOS 0\.4\.15 after the previous release manager was unable to continue working on the project\. I’m pleased to announce that I was hired for a full\-time contract position with ReactOS Deutschland e\.V\. in May of 2025\.
