v0.3.0

This is the third release of cosign!

We still expect many flags, commands, and formats to change going forward, but we're getting closer.
No backwards compatiblity is promised or implied yet, though we are hoping to formalize this policy in the next release.
See #254 for more info.

• The -key flag now supports kms references and URLs, the kms specific flag has been removed
• Yubikey/PIV hardware support is now included!

v0.1.0

There were some ups and downs in today's release, but it's finally time to ride the cosign wave! After battling some last minute test flakes that were popping up at an alarming frequency and running in circles trying to squaring up loose ends, I couldn't find any other tangents to go off on. The first release is here!

My only regret is not thinking to get this release out on Pi day :(

Enhancements

This release added a feature to cosign called cosign. The cosign feature can be used to sign container images and blobs.

Bug Fixes

There was no way to sign container images. Now there is!

Known Issues

This release only contains a linux/amd64 binary. You can build and install cosign on other platforms with go install, but the main goal of v0.1.0 is to get a working build we can start packing to make signing releases of other tools easier. We'll add other platforms to the next set of releases!

Verifying

This release was self-signed! It was built in this Action run: https://github.com/sigstore/cosign/actions/runs/669626925

The public key used to sign this release is located here: https://github.com/sigstore/cosign/blob/083406c6e85284ded34af96048361d1e8c887e50/.github/workflows/cosign.pub

You should be able to verify it with the cosign verify-blob command using this key. Good luck!
