Up to date documentation on D implementation.

[ReneSac]

Hi.

I'm totally new to D, and would like to use it to prototype some 
compression software ideas. But everywhere in old posts I see 
that some XYZ feature of the language is buggy, subject to 
change, etc. But I don't know how it is today, and I would rather 
not learn what is wrong with the feature in the hard way, by 
stumbling in the compiler bugs. My hand will be full with my own 
bugs, and I would like to suppose an correctly working language...

So, is there any up to date documentation on D implementation, 
saying what is stable, what is beta quality (and I should use 
with caution), what is alpha (and I should really avoid), and 
what is unimplemented?

Also, witch compiler I should use? In the 
[url=http://dlang.org/dmd-windows.html]DMD requirements[/url], it 
says "32 bit Windows (Win32) operating system, such as Windows 
XP", so I guess I'm out of luck with Windows 7 64 bits... Do I 
really have to use a VM to develop in D for running in Windows? 
And on linux, which is the most stable? Which is the faster one 
for my use case?

Thanks.
