Prior to this change, a K8s branch (master as well as release) was pinned to a GCI milestone. It would pick up the latest GCI release on that milestone at the time of cluster creation. The rationale was the K8s users would automatically get the bug fixes in newer versions of GCI. However in practice, it makes the runtime environment non-deterministic, and lack of continuous e2e tests mean we would run into breakages sooner or later. With this change, each K8s release will pick a specific version of GCI by default (similar to how the Debian-based container-vm gets used). Users can override the default version through KUBE_GCE_MASTER_IMAGE and KUBE_GCE_NODE_IMAGE environment variables. We expect the default GCI version will be updated relatively frequently stay updated with newer GCI releases. We can also automate the process to automatically bump the hard-coded GCI version in future.
