BREAKING CHANGES

• The ec2.Connections object has been changed to be able to manage multiple
  security groups. The relevant property has been changed from securityGroup
  to securityGroups (an array of security group objects).
• aws-codecommit: this modifies the default behavior of the CodeCommit
  Action. It also changes the internal API contract between the
  aws-codepipeline-api module and the CodePipeline Actions in the service
  packages.
• applets: The applet schema has changed to allow Multiple applets can be
  define in one file by structuring the files like this:
• applets: The applet schema has changed to allow definition of multiple
  applets in the same file.

The schema now looks like this:

applets:
  MyApplet:
    type: ./my-applet-file
    properties:
      property1: value
      ...

By starting an applet specifier with npm://, applet modules can directly be
referenced in NPM. You can include a version specifier (@1.2.3) to reference
specific versions.

• aws-sqs: queue.grantReceiveMessages has been removed. It is unlikely
  that this would be sufficient to interact with a queue. Alternatively you can
  use queue.grantConsumeMessages or queue.grant('sqs:ReceiveMessage') if
  there's a need to only grant this action.

v0.14.1

Bug Fixes

• aws-cdk: fix bug in SSM Parameter Provider (#1023) (6e6aa1d)

v0.14.0

IMPORTANT NOTE: when upgrading to this version of the CDK framework, you must also upgrade
your installation the CDK Toolkit to the matching version:

$ npm i -g aws-cdk
$ cdk --version
0.14.0 (build ...)

BREAKING CHANGES

• DynamoDB AutoScaling: Instead of addReadAutoScaling(), call autoScaleReadCapacity(), and similar for write scaling.
• CloudFormation resource usage: If you use L1s, you may need to change some XxxName properties back into Name. These will match the CloudFormation property names.
• You must use the matching aws-cdk toolkit when upgrading to this version, or context providers will cease to work. All existing cached context values in cdk.json will be invalidated and refreshed.
• ec2.AllConnections was renamed to ec2.AllTraffic.

v0.13.0

Highlights

• A new construct library for AWS Step Functions
  (docs).
  The library provides rich APIs for modeling state machines by exposing a
  programmatic interface for Amazon State
  Language.
• A new construct library for Amazon S3 bucket deployments
  (docs).
  You can use now automatically populate an S3 Bucket from a .zip file or a
  local directory. This is a building block for end-to-end support for static
  websites in the AWS CDK.

• aws-s3-deployment: bucket deployments (#971) (84d6876), closes #952 #953 #954
• docs: added link to CloudFormation concepts (#934) (666bbba)

BREAKING CHANGES

• aws-apigateway: specifying a path no longer works. If you used to
  provide a '/', remove it. Otherwise, you will have to supply proxy: false
  and construct more complex resource paths yourself.
• aws-lambda: The construct lambda.InlineJavaScriptLambda is no longer supported. Use lambda.Code.inline instead; lambda.Runtime.NodeJS43Edge runtime is removed. CloudFront docs stipulate that you should use node6.10 or node8.10. It is always possible to use any value by instantiating a lambda.Runtime object.

v0.12.0

IMPORTANT NOTE: This release includes a fix for a bug
that would make the toolkit unusable for multi-stack applications. In order to benefit from
this fix, a globally installed CDK toolkit must also be updated:

$ npm i -g aws-cdk
$ cdk --version
0.12.0 (build ...)

Like always, you will also need to update your project's library versions:

Language	Update?
JavaScript/TypeScript (npm)	npx npm-check-updates -u
Java (maven)	mvn versions:use-latest-versions
.NET (NuGet)	nuget update

Bug Fixes

• aws-codebuild: allow passing oauth token to GitHubEnterpriseSource (#908) (c23da91)
• toolkit: multi-stack apps cannot be synthesized or deployed (#911) (5511076), closes #868 #294 #910

Features

• aws-cloudformation: add permission management to CreateUpdate and Delete Stack CodePipeline Actions. (#880) (8b3ae43)
• aws-codepipeline: make input and output artifact names optional when creating Actions. (#845) (3d91c93)

BREAKING CHANGES

• aws-codepipeline: this commit contains the following breaking changes:
  • Rename 'artifactName' in Action construction properties to 'outputArtifactName'
  • Rename the 'artifact' property of Actions to 'outputArtifact'
  • No longer allow adding output artifacts to Actions by instantiating the Artifact class
  • Rename Action#input/outputArtifacts properties to _input/_outputArtifacts

Previously, we always required customers to explicitly name the output artifacts the Actions used in the Pipeline,
and to explicitly "wire together" the outputs of one Action as inputs to another.
With this change, the CodePipeline Construct generates artifact names,
if the customer didn't provide one explicitly,
and tries to find the first available output artifact to use as input to a newly created Action that needs it,
thus turning both the input and output artifacts from required to optional properties.

v0.11.0

IMPORTANT NOTE: This release includes a breaking change
in the toolkit <=> app protocol. This means that in order to synthesize CDK apps that use this version,
the globally installed CDK toolkit must also be updated:

$ npm i -g aws-cdk
$ cdk --version
0.11.0 (build ...)

Like always, you will also need to update your project's library versions:

Language	Update?

Java (maven)	mvn versions:use-latest-versions
.NET (NuGet)	nuget update

v0.10.0

This release introduces a better way to "escape" L2 constructs in case of missing features
by adding the ability to add arbitrary overrides for resource properties:

const bucket = new s3.Bucket(this, 'L2Bucket');

// access L1
const bucketResource = bucket.findChild('Resource') as s3.cloudformation.BucketResource;

// strongly-typed overrides
bucketResource.propertyOverrides.bucketName = 'NewBucketName';

// weakly-typed overrides
bucketResource.addPropertyOverride('BucketName', 'NewerBucketName');

• core: resource overrides (escape hatch) (#784) (5054eef), closes #606
• toolkit: stop creating 'empty' stacks (#779) (1dddd8a)

BREAKING CHANGES

• cdk: the constructor signature of TagManager has changed. initialTags is now passed inside a props object.
• util: @aws-cdk/util is no longer available
• aws-elasticloadbalancingv2: adds classes for modeling Application and Network Load
  Balancers. AutoScalingGroups now implement the interface that makes
  constructs a load balancing target. The breaking change is that Security
  Group rule identifiers have been changed in order to make adding rules
  more reliable. No code changes are necessary but existing deployments
  may experience unexpected changes.
• aws-cloudformation: this renames all CloudFormation Actions for CodePipeline
  to bring them in line with Actions defined in other service packages.
• aws-codepipeline, aws-codecommit, aws-s3: change the names of the source Actions from XxxSource to XxxSourceAction.
  This is to align them with the other Actions, like Build.
  Also, CodeBuild has the concept of Sources, so it makes sense to strongly differentiate between the two.

v0.9.2

NOTICE: This release includes a framework-wide breaking change which changes the type of all the string resource attributes across the framework. Instead of using strong-types that extend cdk.Token (such as QueueArn, TopicName, etc), we now represent all these attributes as normal strings, and codify the tokens into the string (using the feature introduced in #168).

Furthermore, the cdk.Arn type has been removed. In order to format/parse ARNs, use the static methods on cdk.ArnUtils.

See motivation and discussion in #695.

• cfn2ts: use stringified tokens for resource attributes instead of strong types (#712) (6508f78), closes #518 #695 #744
