Can we fix the links to gdcproject.org or change the site?

[James Lu]

Hello,

The links on the D IRC channel as well as 
https://dlang.org/download.html for GDC all point to 
https://gdcproject.org/downloads, which last appears to be 
updated several years ago.

Can we archive the old site and make GDC's website redirect to, 
say, a GCC 11 nightly build? Perhaps it should also have some 
information on what features are missing and/or the DMDFE version.

It looks bad to have one of the main compilers point to a website 
with downloads timestamped "2016."
