Release Notes

sigstore/cosign-installer (sigstore/cosign-installer)

v4.0.0

Compare Source

What's Changed?

Note: You must upgrade to cosign-installer v4 if you want to install Cosign v3+. You may still install Cosign v2.x with cosign-installer v4.

In version v3+, using cosign sign-blob requires adding the --bundle flag which may require you to update your signing command.

• Add support for Cosign v3 releases (#​201)

v3.10.1

Compare Source

What's Changed?

Note: cosign-installer v3.x cannot be used to install Cosign v3.x. You must upgrade to cosign-installer v4 in order to use Cosign v3.

Note: This is planned to be the final release of Cosign v2, though we will cut new releases for any critical security or bug fixes. We recommend transitioning to Cosign v3.
