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.) ?
