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

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.
