<div dir="ltr">I would strongly urge that any new tarballs be released under new names, and that the old tarballs be kept in place. Changing existing tarball URLs silently causes breakage for Nix, and, I would imagine, for any other build systems that are particularly concerned with reproducibility. Nix packages based on GHC use an SHA-256 hash of the tarball to check it when downloading, which of course will be broken by any change, no matter how minor.<div><br></div><div>Of course, this doesn't necessarily impact the version number directly.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Apr 4, 2017 at 8:15 AM, Phyx <span dir="ltr"><<a href="mailto:lonetiger@gmail.com" target="_blank">lonetiger@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><p dir="ltr">We have discussed a few options on what to do, but haven't gotten a conclusion/concensus yet. </p>

See [1] for the previous discussion, [2] and [3] for the tickets discussing this. From what I read on the GHC 8.2 status wiki page, there might be an interval of some weeks where it will not be possible to compile a Haskell program on any up-to-date Windows
