[1.1.18] — 2026-04-02

Added

• EC2 DescribeInstanceCreditSpecifications — returns standard CPU credits; fixes Terraform v6 provider compatibility
• EC2 Terraform v6 stubs — DescribeInstanceMaintenanceOptions, DescribeInstanceAutoRecoveryAttribute, ModifyInstanceMaintenanceOptions, DescribeInstanceTopology, DescribeSpotInstanceRequests, DescribeCapacityReservations all return sensible empty/default responses
• Lambda Node.js warm worker pool — Node.js functions now use the same persistent warm worker as Python; supports async/await, Promise, and callback handlers; AWS SDK v2 endpoint patching for local development
• Docker image includes Node.js — nodejs added to Alpine base image so container-based Node.js Lambda execution works out of the box in Docker Compose / CI environments
• Lambda S3 code fetch — CreateFunction and UpdateFunctionCode now accept S3Bucket/S3Key in addition to ZipFile; returns error if S3 object not found
• Lambda versioning — Publish=True on CreateFunction and UpdateFunctionCode now creates immutable numbered versions with their own code_zip
• DynamoDB Streams — StreamSpecification on CreateTable now emits INSERT/MODIFY/REMOVE records on all write operations (PutItem, UpdateItem, DeleteItem, BatchWriteItem, TransactWriteItems); respects StreamViewType
• Kinesis ESM polling — Lambda event source mappings now support Kinesis streams in addition to SQS

Fixed

• SNS Subscribe ignores Attributes parameter — RawMessageDelivery, FilterPolicy, FilterPolicyScope, DeliveryPolicy, and RedrivePolicy passed at subscription creation time are now applied immediately

• Lambda warm worker not invalidated on code update — UpdateFunctionCode and DeleteFunction now invalidate the warm worker pool so the next invocation picks up the new code

• Lambda module-level imports — removed lazy from ministack.core.lambda_runtime import inside functions; moved to module top level

• S3 chunked transfer encoding — AWS SDK v2 sends PutObject with STREAMING-AWS4-HMAC-SHA256-PAYLOAD chunked encoding; body was stored with chunk headers causing corrupt GetObject responses; now decoded before storage

• Kinesis validation limits — PutRecord and PutRecords now enforce AWS limits: max 1 MB per record, max 500 records per batch, max 5 MB total payload, max 256-char partition key

• S3 Control routing via s3-control.localhost host — requests with host header s3-control.localhost were intercepted by the S3 virtual-hosted bucket handler instead of reaching the S3 Control API; fixes Terraform ListTagsForResource returning 404 NoSuchResource

• EC2 security group rule deduplication — AuthorizeSecurityGroupIngress/Egress no longer appends duplicate rules; fixes Terraform showing constant drift

• EC2 default egress rule on created security groups — non-default security groups now include the standard allow-all egress rule matching AWS behaviour

• EC2 VPC Peering missing Region field — requesterVpcInfo and accepterVpcInfo now include <region> in all responses; fixes Terraform failing to parse peering connections

• Lambda PublishVersion FunctionArn — no longer appends version number to FunctionArn (version is in the Version field); fixes Terraform ARN comparison drift

• Lambda FunctionUrlConfig hardcoded region — now uses MINISTACK_REGION instead of hardcoded us-east-1

• Lambda handler validation — returns proper Runtime.InvalidEntrypoint error if handler name has no . separator instead of crashing

• RDS error code — DBInstanceAlreadyExists corrected to DBInstanceAlreadyExistsFault matching AWS error codes

• Thanks to @lubond @jimmyd-be @abedurftig @mig_mit for reporting issues and testing
