ReactOS Online Front Page

ReactOS is an Open Source effort to develop a quality operating system that is compatible with Windows NT applications and drivers.

Relationship with the WINE project
ReactOS has always planned to work with the WINE project to share as much programming effort as possible.
This will mainly concern User Mode DLLs and will happen once ReactOS's Kernel Mode areas are more complete, as those areas form the underlying infrastructure. Other areas of cooperation lie in applications and testing suites.


Future compatibility
The ReactOS project, although currently focused on Windows NT 4.0 compatibility, is always keeping an eye towards compatibility with future Windows NT releases, that is, Windows 2000 (NT 5.0) and Windows XP (NT 5.1).


Supporting other System Applications

More details:
http://www.reactos.com/
The Windows NT architecture allows for subsystems, as does the ReactOS architecture. A subsystem is an implementation of the APIs of another operating system, allowing ReactOS to run applications from other systems. We are already looking at subsystems for: Java, OS/2 and DOS and possibly others in the future.

ReactOS 0.3.4 Released
A new release of the ReactOS operating system

ReactOS 0.3.4 Released
We are pleased to announce the release of the next version of ReactOS in the 0.3 series. This is a culmination of the last 3 months of development, and some significant progress has been made in various areas.

Release cycle
Starting from version 0.3.3 we have aimed to move our release cycle to a 2 month period. There are various reasons for this, but the two which are key to this decision is a desire to keep the main development tree in a stable condition, and an effort to keep up the interests of the people who follow the project, by providing regular release builds to play with.

To explain the first one in a little more detail; one of the problems we were experiencing as a project was huge system regressions at release time. Our release cycle used to be around the 6 month mark and we were finding that after 6 months of heavy development, we would branch and start to test only to find regressions had appeared all over the operating system. A list of blockers was then generated and this could take a huge amount of time to clear, at which point developers were concentrating on trying to fix regressions and development came to a halt.

We stumbled across this post from Linus Torvalds which showed the linux kernel was experiencing the same problems we were having, and discusses the changes which worked for Linux.

We opted for a similar approach of shortening the release cycle, which is keeping our main trunk much more stable and means we can virtually release trunk ‘as is’ without the need for lengthy branch periods. It also means more releases from the project, which is hoped will raise awareness and interest in ReactOS.

We did slightly overshoot the 2 month release period, but this is to be expected whilst we bring the new model into play. We expect to meet our targets with greater ease as the model becomes more established.
