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.
