I have started the process of migrating GHC’s Trac content to GitLab.
GitLab (https://gitlab.haskell.org) and Trac (https://ghc.haskell.org) will be down
until this process has finished. I will post updates as necessary.
However, if you do need to refer to a ticket, you are welcome to use the
staging server, which has a reasonably up-to-date (read-only)
snapshot of our Trac tickets. However, do note that unfortunately
authentication via GitHub will not work on this site.
