 ### Additions
 
 - Add "panic" level for --zap-stacktrace-level (allows "debug", "info", "error", "panic"). ([#3040](https://github.com/operator-framework/operator-sdk/pull/3040))
-- The `operator-sdk` binary has a new CLI workflow and project layout for scaffolding Go operators that is aligned with Kubebuilder's CLI and project layout. See the new [Quickstart Guide](https://master.sdk.operatorframework.io/docs/golang/quickstart) and the new [CLI reference](https://master.sdk.operatorframework.io/docs/new-cli) for more details. ([#3190](https://github.com/operator-framework/operator-sdk/pull/3190))

([#3190](https://github.com/operator-framework/operator-sdk/pull/3190))
 - `bundle validate` can now use a containerd image ("none") tool to unpack images, removing the need for an external image tool like docker/podman. ([#3222](https://github.com/operator-framework/operator-sdk/pull/3222))
 - The SDK `scorecard` command adds a new test image, scorecard-test-kuttl, that allows end users to write and execute kuttl based tests. ([#3278](https://github.com/operator-framework/operator-sdk/pull/3278))
 - Add "--olm-namespace" flag to olm subcommands (install, uninstall) to allow users to specify the  namespace where olm is to be installed or uninstalled. ([#3300](https://github.com/operator-framework/operator-sdk/pull/3300))

 ### Removals
 
-- The `operator-sdk new` command no longer supports scaffolding new Go projects with the `--type=Go` flag.  To scaffold new projects, users are expected to use `operator-sdk init` as part of the  [new CLI](https://master.sdk.operatorframework.io/docs/new-cli) for Go operators.

 ### Deprecations
 
-- With the introduction of the new [Kubebuilder aligned CLI](https://master.sdk.operatorframework.io/docs/new-cli)  and project layout for Go operators, the [old CLI](https://sdk.operatorframework.io/docs/cli)  will still continue to work for Go projects scaffolded in the old layout with `operator-sdk new`. However the old CLI is now deprecated and will be removed in a future release. ([#3190](https://github.com/operator-framework/operator-sdk/pull/3190))

 - Deprecate 'operator-sdk add crd'. Use 'operator-sdk add api' instead. ([#3180](https://github.com/operator-framework/operator-sdk/pull/3180))
 - `bundle create` is deprecated in favor of a combination of `generate bundle` and `docker build -f bundle.Dockerfile ...`. ([#3323](https://github.com/operator-framework/operator-sdk/pull/3323))
