The cause is GitHub deprecating the undocumented cache API that Magic Nix Cache relied on, replacing it with a new Twirp/Protocol Buffers-based API whose .proto source files have not been released. With insufficient time to reverse-engineer or rewrite the integration, the free GitHub-Actions-based cache will be discontinued. Users are directed to migrate to FlakeHub Cache, with a one-month free coupon available, and open source maintainers can request a free account. ## Full article daily.dev links to this article rather than hosting it.
