+## PR [#814](https://github.com/cloudposse/terraform-aws-components/pull/814)
+
+### Possible Breaking Change
+
+The `module "datadog_integration"` and `module "store_write"` had been changed
+in an earlier PR from a module without a `count`
+to a module with a `count` of zero or one. This PR changes it back to a module
+without a count. If you were using the module with a `count` of zero or one,
+applying this new version will cause it be destroyed and recreated. This should only
+cause a very brief outage in your Datadog monitoring.
+
+### New Integration Options
+
+This PR adds the following new integration options:
+
+- `cspm_resource_collection_enabled` - Enable Datadog Cloud Security Posture Management scanning of your AWS account. See [announcement](https://www.datadoghq.com/product/cloud-security-management/cloud-security-posture-management/) for details.
+- `metrics_collection_enabled` - When enabled, a metric-by-metric crawl of the CloudWatch API pulls data and sends it
+to Datadog. New metrics are pulled every ten minutes, on average.
+- `resource_collection_enabled` - Some Datadog products leverage information about how your AWS resources (
+such as S3 Buckets, RDS snapshots, and CloudFront distributions) are configured.
+When `resource_collection_enabled` is `true`, Datadog collects this information
+by making read-only API calls into your AWS account.
