v1.6.0-rc1

[cube2222]

Time for our first prerelease!

This is a big step for us, and if all goes well, this version will become stable on the 10th of January.

This version includes the new module testing feature, an updated s3 backend, tons of minor improvements, bug fixes, and performance improvements. It also includes our new registry.

This release is a great time to take OpenTofu for a spin, integrate it with your 3rd party tooling, and prepare for the stable release coming soon. You can find our simple migration guide in our documentation.

Importantly, we've changed the identity of the cosign signatures to the new version branch, which means that when verifying binaries from GitHub releases, you'll need to pass --certificate-identity https://github.com/opentofu/opentofu/.github/workflows/release.yml@refs/heads/v1.6. This is because branch protection is much stronger than tag protection in GitHub.

You can find the full changelog here.
