+### @aws-cdk/aws-apigateway:requestValidatorUniqueId
+
+*Generate a unique id for each RequestValidator added to a method* (fix)
+
+This flag allows multiple RequestValidators to be added to a RestApi when
+providing the `RequestValidatorOptions` in the `addMethod()` method.
+
+If the flag is not set then only a single RequestValidator can be added in this way.
+Any additional RequestValidators have to be created directly with `new RequestValidator`.

+### @aws-cdk/aws-ec2:restrictDefaultSecurityGroup
+
+*Restrict access to the VPC default security group* (default)
+
+Enable this feature flag to remove the default ingress/egress rules from the
+VPC default security group.
+
+When a VPC is created, a default security group is created as well and this cannot
+be deleted. The default security group is created with ingress/egress rules that allow
+_all_ traffic. [AWS Security best practices recommend](https://docs.aws.amazon.com/securityhub/latest/userguide/ec2-controls.html#ec2-2)
+removing these ingress/egress rules in order to restrict access to the default security group.

+| Since | Default | Recommended |

+| V2·NEXT | `false` | `true` |
+
+**Compatibility with old behavior:** 
+      To allow all ingress/egress traffic to the VPC default security group you
+      can set the `restrictDefaultSecurityGroup: false`.
+
+
+
+### @aws-cdk/aws-kms:aliasNameRef
+
+*KMS Alias name and keyArn will have implicit reference to KMS Key* (fix)
+
+This flag allows an implicit dependency to be created between KMS Alias and KMS Key
+when referencing key.aliasName or key.keyArn.
+
+If the flag is not set then a raw string is passed as the Alias name and no
+implicit dependencies will be set.

+### @aws-cdk/aws-route53-patters:useCertificate
+
+*Use the official `Certificate` resource instead of `DnsValidatedCertificate`* (default)
+
+Enable this feature flag to use the official CloudFormation supported `Certificate` resource instead
+of the deprecated `DnsValidatedCertificate` construct. If this flag is enabled and you are creating
+the stack in a region other than us-east-1 then you must also set `crossRegionReferences=true` on the
+stack.
