🎉 Highlights

This release adds four new services (EMR, WAF v2, AWS Batch, RDS Data API), lands a substantial Glue partition and statistics pass, brings RDS provisioning support, and ships meaningful CloudFormation improvements with Lambda-backed custom resources and EC2 VPC/subnet provisioning. ELBv2, S3, SES, and ECS all see solid conformance work. Welcome to first-time contributor @LorenzoGalassi.

🆕 Four new services

• Amazon EMR management API (Phase 1) (#1321)
• AWS WAF v2 management API (Phase 1) (#1327)
• AWS Batch service support (#1332)
• RDS Data API (#1262)

That's a major catalog expansion in one release: from analytics (EMR) and edge security (WAF v2) to batch compute (Batch) and serverless SQL (RDS Data API).

🗄️ RDS provisioning support

Beyond the existing real-Docker-backed RDS engines, provisioning lifecycle is now supported (#1253), so the full create / describe / modify / delete flow works as real AWS would handle it.

🪨 Glue: partitions, statistics, and determinism

A coordinated Glue Data Catalog pass lands this cycle:

• Partition APIs support (#1315)
• Column statistics support (#1309)
• Table statistics deletion (#1324)
• Missing table deletes rejected (#1323)
• Deterministic partition ordering from GetPartitions (#1335)

🧱 CloudFormation: custom resources + VPC/subnet provisioning

Two notable CloudFormation improvements:

• Lambda-backed custom resources (AWS::CloudFormation::CustomResource) and layer versions now provision (#1146)
• EC2 VPC and subnet resources provision via CloudFormation so cross-stack exports resolve correctly (#1342)

🔐 STS session secret persistence

A subtle but important fix: STS session secret keys now persist (#1266), so IAM-token-based authentication against RDS and ElastiCache actually validates across requests.

🚨 SQS message size correction

MaximumMessageSize upper bound corrected from 256KB to the actual AWS maximum of 1MB (#1339). If your tests relied on Floci rejecting messages between 256KB and 1MB, those will now pass as they do in real AWS.
