Suggested change
# Multi-platform digest for Cosign v2.4.0
# Multi-platform digest for Cosign v2.4.0
# We pin Cosign to v2.4.0 for compatibility with our signing and verification scripts.
# If you need to update Cosign, ensure that all scripts and workflows using Cosign are tested with the new version.
# Check for breaking changes in Cosign's release notes: https://github.com/sigstore/cosign/releases
# Update the digest and version only after confirming compatibility.
