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.
