We are enabling CgroupV2 support globally, which requires Docker 20.10. It is possible to return to CgroupV1 locally via kernel commandline, but that will still work with Docker 20. If someone really needs older Docker versions we will recommend to also fetch torcx packages from older releases or rely on upstream binaries.
