Vendor updated containers/image and containers/storage, along with any new dependencies they drag in, and updated versions of other dependencies that happen to get pulled in. github.com/coreos/go-systemd/daemon/SdNotify() now takes a boolean to control whether or not it unsets the NOTIFY_SOCKET variable from the calling process's environment. Adapt. github.com/opencontainers/runtime-tools/generate/Generator.AddProcessEnv() now takes the environment variable name and value as two arguments, not one. Adapt.
