+* v0.12.2: Add proper CORS headers to S3 responses; expose SecretsManager secrets via SSM parameter references; fix parsing of Content-Disposition header in S3 multipart uploads; add carriage return to SQS message payload validation regex; add support for SQS queue names containing slashes; add support for resource policies in SecretsManager; add test for S3 precondition check; add test for Terraform API Gateway resources; use distinct values for missing CloudFormation resource props; handle non-zero ReceiveMessageWaitTimeSeconds for SQS; refactor CF tests; add support for custom CI build commands via $CUSTOM_CMD; add README instructions for test credentials required for presigned URLs; fix Content-Length mismatch issue for HTTP server responses; add util function to create API GW Lambda event request context; fix hypercorn response body on 412 status code; upgrade base image and local Lambda executor to Java 11; allow adding multiple permission statements to Lambda function policy; minor: fix logic for missing authorizerId in API GW authorizers
 * v0.12.1: Fix missing module import for Windows; set correct Id attribute in S3 notification messages; enable setting custom authorizers on API GW resource methods; add log output listener for shell command thread; fix DynamoDB streams sequence number mismatch on GetRecords; add docs about using AWS CLI v2 from Docker image; updates in developer documentation and README (e.g., docker-compose version); support filtering of events by pattern using eventPattern; add CloudFormation support for Lambda::Permission; fix date format in CloudWatch responses; fix service name and NS URLs for XML service responses; add Terraform test for several resources (Lambdas, S3 bucket CORS integration); fixed gzip encoding for empty response content; refactor StepFunctions integration tests; pass $EDGE_PORT to Lambdas; add test for creating SFN State Machine with Choice operator; add test for creating SQS queue with attributes via CloudFormation
 * v0.12.0: Single edge port now stable for all APIs; publish SNS messages asynchronously; fix edge route mapping for S3 HEAD requests; fix invalid account ID in CloudWatch logs listener ARNs; minor fix of XML root tag for S3 error responses; fix issue with blocking sockets in HTTP2 server; minor refactoring of /graph endpoint; fix numeric timestamp format in Kinesis records required by Go SDK; add CloudWatch as a static dependency for Lambda API; disable custom Java Lambda executor and replace with default lambci mechanism; add CBOR encoding support for Kinesis API; raise error when attempting to update CF stack with unmodified template; create env INIT_SCRIPTS_PATH to specify path for init files in Docker; add more fine-grained DynamoDB error injection with read/write error probabilities; extract InputPath expression for notification messages to EventBus targets; fix missing attributes when adding IAM permission to Lambda function; fix case sensitivity for bucket names in S3 bucket notifications; add simple integration test for Terraform resources; fix debug port parser for Java Lambda executor to support different formats; add signature and expiry validation for S3 presigned URLs
 * v0.11.6: !!Breaking Change!! Starting with this release, all services are now exposed via the edge service (port `4566`) only; fix boolean values in IAM responses; fix PutEvents API call with no source specified; add download URLs for Elasticsearch 7.7; minor refactoring in SFN test code; fix endless loop when S3 error document is missing; add integration test to verify MAP tasks in SFN state machines; refactor CF logic for API GW resources and empty/Null values; fix Python path when running Lambdas using local executor; refactor API Gateway utils and test code; refactor Lambda context handling; add LAMBDA_DOCKER_DNS config to utilise custom DNS server for Lambda containers; fix "TypeName" as optional param for Elasticsearch v7; refactor startup logs to print correct ports in output; extend Serverless tests with SQS and API Gateway resources; use S3 path addressing when host starts with localhost IP or hostname; add test to assert event deletion for SQS Lambda event source; fix error response for requests to non-activated APIs; add localhost.localstack.cloud as alias to SSL cert; fix network_mode:bridge in docker-compose.yml; add Serverless integration tests to cover DynamoDB and Kinesis resources; add switch to disable Lambda handler validation; add Lambda request body length check; use edge as single entry point; performance improvements in plugin loading; forward requests in-memory instead of opening port per service
