I don't see a 8.0 preview 4 tag at https://github.com/dotnet/aspire/tags yet.

Yes, I believe @joperezr still needs to create it.

Hello @KalleOlaviNiemitalo, thanks for raising this. This is expected, as we are just waiting on merging the internal branch that is used to build the releases into GH so that we can get the right SHA. We typically do this 1 or 2 days after the actual release, so hopefully I can get this done today.
