-You've now fully released a new version of the Operator SDK. Good work! Make sure to follow the post-release steps below.
-
-### (Post-release) Updating the operator-sdk-samples repo
-
-Many releases change SDK API's and conventions, which are not reflected in the [operator-sdk-samples repo][sdk-samples-repo]. The samples repo should be updated and versioned after each SDK major/minor release with the same tag, ex. `v1.3.0`, so users can refer to the correct operator code for that release.
-
-The release process for the samples repo is simple:
-
-1. Make changes to all relevant operators (at least those referenced by SDK docs) based on API changes for the new SDK release.
-1. Ensure the operators build and run as expected (see each operator's docs).
-1. Once all API changes are in `master`, create a release tag locally:
-    ```sh
-    $ git checkout master && git pull
-    $ export VER="v1.3.0"
-    $ git tag --sign --message "Operator SDK Samples $VER" "$VER"
-    ```
-1. Push the tag to the remote, assuming `upstream` is the name of the upstream remote:
-    ```sh
-    $ git push upstream $VER
-    ```
-
-### (Post-release) Updating the release notes
-
-Add the following line to the top of the GitHub release notes for `v1.3.0`:

-```md
-**NOTE:** ensure the `v1.3.0` tag is referenced when referring to sample code in the [SDK Operator samples repo](https://github.com/operator-framework/operator-sdk-samples/tree/v1.3.0) for this release. Links in SDK documentation are currently set to the samples repo `master` branch.
