+### ⚠ BREAKING CHANGES
+
+* L1 resources are automatically generated from
+public CloudFormation Resource Schemas. They are built to closely
+reflect the real state of CloudFormation. Sometimes these updates can
+contain changes that are incompatible with previous types, but more
+accurately reflect reality. In this release we have changed:
+
+aws-appstream: AWS::AppStream::Stack: Id attribute removed.
+aws-appsync: AWS::AppSync::GraphQLApi: LogConfig.CloudWatchLogsRoleArn
+property is now required.
+aws-appsync: AWS::AppSync::GraphQLApi: LogConfig.FieldLogLevel property
+is now required.
+aws-kafkaconnect: AWS::KafkaConnect::Connector:
+ProvisionedCapacity.McuCount property is now required.
+
