+It's now possible to use the credentials from the `integrations.awsS3` config to authenticate with AWS S3. The new priority is:
+
+1. `aws.accounts`
+2. `techdocs.publisher.awsS3.credentials`
+3. `integrations.awsS3`
+4. Default credential chain
+
+In case of multiple `integrations.awsS3` are present, the target integration is determined by the `accessKeyId` in `techdocs.publisher.awsS3.credentials` if provided. Otherwise, the default credential chain is used.
