D Programming Language source (dmd, phobos, etc.) has moved to github

[David Wang]

Dear Walter,

I went to the github and try to download the source, I found that
the latest version on github is the old version.

for example:

druntime - Downloads: dmd-2.042
Phobos -   Downloads: phobos-2.046
DMD -      Downloads: dmd-2.046

I think the actural latest version of D should be 2.051.

Why github can not showing the 2.051 version(dmd, phobos,
druntime, and so on.) ?
