ReactOS is in development since 1998, so there's no "great news" about this.
Because ReactOS wasn't ready for the time I moved away from Windows in favour
for free software, I opted for Trisquel GNU/Linux instead, which I needed to
wait 3 years to become usable with the release of version 4.0 in 2010 (that I
still use on my older ThinkPad computer).
Where the GNU project and Free Software Foundation aimed to develop a
fully-free operating system, mimicking the Unix, there is ReactOS and the
ReactOS Foundation. Unlike GNU, the goal is to make a free replacement for
Windows that's binary compatible with the already available software/drivers.
Nowadays, despite many fundraising efforts, ReactOS remains a hobby project
lead by some few developers. It's developed by clean-room
reverse-engineering, so the developers doesn't use any code or binaries from
Microsoft, but some of the source code is shared with the Wine project. The
ReactOS uses it's own kernel, compatible with the Windows NT architecture.
