Announcing the next major release of Cosign!

Cosign v3 is a minor change from Cosign v2.6.x, with all of the new capabilities of recent
releases on by default, but will still allow you to disable them if you need the older functionality.
These new features include support for the standardized bundle format (--new-bundle-fomat), providing roots
of trust for verification and service URLs for signing via one file (--trusted-root, --signing-config),
and container signatures stored as an OCI Image 1.1 referring artifact.

Learn more on our v3 announcement blog post! See
the changelogs for v2.6.0, v2.5.0, and v2.4.0 for more information on recent
changes.

If you have any feedback, please reach out on Slack or file an issue on GitHub.

Changes

  • Default to using the new protobuf format (#​4318)
  • Fetch service URLs from the TUF PGI signing config by default (#​4428)
  • Bump module version to v3 for Cosign v3.0 (#​4427)

Summary of Changes

Hello @renovate-bot, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request performs a major version upgrade of the github.com/sigstore/cosign module from v2.6.1 to v3.0.2. This update introduces several new capabilities that are now enabled by default, such as the standardized bundle format and enhanced trust mechanisms. A notable change for users is that the --bundle flag, previously optional, is now a required parameter for specifying the Sigstore bundle output.

Highlights

  • Major Version Upgrade: The github.com/sigstore/cosign module has been updated from v2.6.1 to v3.0.2, representing a significant major version bump.
  • New Default Capabilities: Cosign v3 introduces new features that are now enabled by default, including the standardized bundle format, trusted roots for verification, and container signatures stored as OCI Image 1.1 referring artifacts.
  • Required Bundle Flag: The --bundle flag, used to specify an output file for the Sigstore bundle, has transitioned from an optional parameter to a required one in Cosign v3.

Code Review

This pull request updates github.com/sigstore/cosign from v2 to v3. As this is a major version bump, it introduces breaking changes that require manual intervention. The go.mod file now contains a duplicate dependency for cosign/v3, which needs to be removed. More importantly, the source code in pre-sync/oci-image-verification/main.go must be updated to use the new cosign/v3 import paths and any changed APIs. Without these updates, the project will not compile.
