ReactOS® is a free, modern operating system based on the design of Windows® XP/2003. Written completely from scratch, it aims to follow the Windows-NT® architecture designed by Microsoft from the hardware level right through to the application level. This is not a Linux based system, and shares none of the unix architecture.
It's difficult to sum up all of the changes which have taken place in the memory manager short of saying it's been almost a total rewrite. These changes have not only brought a much more stable and reliable component, but also now includes support for ARM processors. ARM memory management units (MMU’s) are handled in an entirely different manner than that of x86 and x86-64 MMU’s, however the ARM Mm component has been written alongside the x86 component with various areas sharing code when possible. Further to this, these changes bring much improved compatibility with WinDbg. WinDbg support is now at a level where the majority of everyday features are working and tasks which previously seemed so distant using WinDbg, such as stepping through the kernel, listing process threads or dynamically editing memory are now working. We're now at a level where having PDB's (Microsoft's debugging symbols) would make debugging the reactos kernel a similar experience to debugging the Windows kernel, with the added advantage of source mode.
The sound stack continues to see extensive work throughout all areas. This release brings with it support for wave recording and mixer support such as volume level adjustment and muting. Improved core component compatibility with WinXP means that more components now run within Windows and goes some way to showing the level of compatibility the sound stack is now achieving.
Compatibility and stability changes have been continuing throughout the entire operating system with a great deal of fixes coming from the Wine test framework used to ensure application interface compatibility.
