# Utilities for parsing Kubernetes changelog.
# find_latest_patch_version finds the latest released patch version for the
# given branch.
# We use the version to track what API surface the generated Python client
# corresponds to, and collect all API change release notes up to that version.
# There is one tricky point: the code generator we use pulls the latest OpenAPI
# spec from the given branch. The spec may contain API changes that aren't
# documented in the Kubernetes release notes. Until the code generator pulls
# the spec from a tag instead of the branch, we can only collect the release
# notes the next time we generate the client.
