+# create-aws-codedeploy-deployment Action Changelog
+
+## Version v0.5.1
+
+- Update action code to use the AWS JavaScript SDK v3, to make warnings about the upcoming v2 EOL go away
+
+## Version v0.5.0
+
+- Added a second action to remove deployment groups, e. g. after a PR has been closed or merged. In order to serve both actions from a single repository, the actions were moved to subdirectories. Refer to actions as `webfactory/create-aws-codedeploy-deployment/create-deployment@v0.5.0` and `webfactory/create-aws-codedeploy-deployment/delete-deployment-group@v0.5.0` respectively in your workflow's `uses:` clause.
+
+## Previous versions
+
+No dedicated changelog file has been written. Refer to https://github.com/webfactory/create-aws-codedeploy-deployment/releases for release information.

 First, this configures AWS Credentials in the GitHub Action runner. The [aws-actions/configure-aws-credentials](https://github.com/aws-actions/configure-aws-credentials) action is used for that, and credentials are kept in [GitHub Actions Secrets](https://help.github.com/en/actions/configuring-and-managing-workflows/creating-and-storing-encrypted-secrets).

 Commits on the `master` branch are to be deployed in a Deployment Group called `production`. All other commits will create or update a Deployment Group named `$BRANCH.staging.acme.tld`, where `$BRANCH` will be replaced with a DNS-safe name derived from the current branch. Basically, a branch called `feat/123/new_gimmick` will use `feat-123-new-gimmick` for `$BRANCH`. Since the Deployment Group Name is available in the `$DEPLOYMENT_GROUP_NAME` environment variable inside your CodeDeploy Lifecycle Scripts, you can use that to create "staging" environments with a single, generic configuration statement.

 ### Input
 
 * `application`: The name of the CodeDeploy Application to work with. Defaults to the "short" repo name.
+* `skip-sequence-check`: When set to `true`, do not attempt to make sure deployments happen in order. Use this when the workflow count has been reset or changed to a lower value; possible cause is renaming the workflow file.
+* `config-name`: Name used to look up the deployment config in the `branch_config` section of the `appspec.yml` file. Defaults to the current branch name. By using this override, you can force a particular config to be used regardless of the branch name. Or, you can run the action several times within the same job to create multiple (different) deployments from the same branch.
 
 ### Outputs
 
 * `deploymentId`: AWS CodeDeployment Deployment-ID of the deployment created
 * `deploymentGroupName`: AWS CodeDeployment Deployment Group name used
-* `deploymentGroupCreated`: True, if a new deployment group was created. False, if an existing group was updated.
+* `deploymentGroupCreated`: `1`, if a new deployment group was created; `0` if an existing group was updated.
+
+You can use the expression `if: steps.<your-deployment-step>.outputs.deploymentGroupCreated==true` (or `...==false`) on subsequent workflow steps to run actions only if the deployment created a new deployment group (or updated an existing deployment, respectively).
+
+## Cleaning Up
+
+Sooner or later you might want to get rid of the CodeDeploy Deployment Groups created by this action. For example, when you create deployments for pull requests opened in a repo, you might want to delete those once the PR has been closed or merged.
+
+To help you with this, a second action is included in this repo that can delete Deployment Groups, and uses the same rules to derive the group name as described above.
+
+Here is an example workflow that runs for closed pull requests:
+
+```yaml
+# .github/workflows/cleanup-deployment-groups.yml
+on:
+    pull_request:
+        types:
+            - closed
+
+jobs:
+    deployment:
+        runs-on: ubuntu-latest
+        steps:
