v2.4.0

Compare Source

v2.4.0 begins the modernization of the Cosign client, which includes:

• Support for the newer Sigstore specification-compliant bundle format
• Support for providing trust roots (e.g. Fulcio certificates, Rekor keys)
  through a trust root file, instead of many different flags
• Conformance test suite integration to verify signing and verification behavior

In future updates, we'll include:

• General support for the trust root file, instead of only when using the bundle
  format during verification
• Simplification of trust root flags and deprecation of the
  Cosign-specific bundle format
• Bundle support with container signing

We have also moved nightly Cosign container builds to GHCR instead of GCR.

Features

• Add new bundle support to verify-blob and verify-blob-attestation (#​3796)
• Adding protobuf bundle support to sign-blob and attest-blob (#​3752)
• Bump sigstore/sigstore to support email_verified as string or boolean (#​3819)
• Conformance testing for cosign (#​3806)
• move incremental builds per commit to GHCR instead of GCR (#​3808)
• Add support for recording creation timestamp for cosign attest (#​3797)
• Include SCT verification failure details in error message (#​3799)
