Release Notes

sigstore/cosign (sigstore/cosign)

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!
