dmd 1.062 and 2.047 release

[Lutger]

Great, thank you!

I noticed both std.concurrency and std.json are not (yet?) included in the documentation. Does that have any bearing on their status, are they usable and / or stable? 

There are some other modules without documentation like std.openrj and std.perf. Is there a page somewhere that documents their fate? I could only find this one:
