Arch has been hosting a patchwork instance for many years and the time has come to retire this service. Most project has been moving to Gitlab, with pacman moving at the end of this year, and there is no real use for this anymore to my knowledge.
Project maintainers should take a look over the projects and collect up any patch links they want to work on in the future. I have posted a small script on the pacman issue if people want to pull old patches from the mailing list.
The EOL date is 1st of January 2023.
We will probably make a static archive of patchwork as a backup incase we need it, but this probably won't be hosted anywhere.
