`v3.1.2`

Compare Source

This may be the last Cosign v3.1 release, as we finish deprecations and removing unused functionality. Soon we'll start work on Cosign v4 where we will remove things that are currently deprecated. We'll continue to support Cosign v3, with it's opt-in backwards compatibility, as described in our versioning policy.

If you haven't already, now is an excellent time to move to the bundle format that has been supported since Cosign v2.6.

We have received a ton of fixes over the past month from folks using Cosign in a variety of environments - thank you all!

`v3.1.1`

Compare Source

What's Changed

Note: v3.1.0 was skipped due to a bug in our release pipeline. v3.1.1 is identical to v3.1.0

This release deprecates a number of flags related to verification material input for trust root material, as well as the bundle format, standardized across Sigstore SDKs, which is now the default output and input for signing and verifying respectively. You may continue to use the deprecated flags with Cosign v3.x releases. The deprecated flags will be removed in a future Cosign v4 release.

This release also updates the signing path for logging to Rekor v2. DSSE attestations will be logged as hashed entries, using the DSSE's pre-auth encoding (PAE). This should unblock developers who want to upload large signed DSSEs such as SBOMs.

`v3.0.2`

Compare Source

v3.0.2 is a functionally equivalent release to v3.0.0 and v3.0.1, with a fix for CI to publish signed releases in the new bundle format.

Note that the --bundle flag specifying an output file to write the Sigstore bundle (which contains all relevant verification material) has moved from optional to required in v3.

Changes

`v3.0.1`

Compare Source

v3.0.1 is an equivalent release to v3.0.0, which was never published due to a failure in our CI workflows.

Note that the --bundle flag specifying an output file to write the Sigstore bundle (which contains all relevant verification material) has moved from optional to required in v3.

Changes

`v3.0.0`

Compare Source

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)

`v2.6.4`

Compare Source

This release is a backport of OCI manifest fixes, and better support for cosign attestation download when you are using a mix of old Cosign signatures with the more recent bundle format.

We strongly encourage folks to continue their migration to the bundle format. The Cosign v3.1.x releases support both formats; the primary change being that the default for signing is the bundle format (although you can specify --new-bundle-format=false to sign with the old format). The verification commands in Cosign v3.1.x support both formats, and will try to detect the format for you for maximum compatibility.

Changelog

26261f0 Allow attestation download to handle both bundle types (#4996) (#5017)
d49a0c1 fix: include artifactType in OCI 1.1 signature referrer manifest (cherry-pick PR-4997 to release-2.6) (#5002)

Thanks to all contributors!
