floci-io/floci 1.5.29 on GitHub

🎉 Highlights

This release adds AppSync Phase 4 with a full VTL engine, lands cross-account assumed-role routing, ships state reset and nuke endpoints, and brings substantial ECS conformance improvements alongside persistence work for Transcribe vocabularies. Welcome to first-time contributor @dnlopes.

🧩 AppSync Phase 4: VTL Engine

The AppSync VTL story completes its build-out across four releases (Phase 1 through Phase 4). This release lands a full VTL Engine (#1288), evaluating template logic end to end. Combined with the Phase 3 $util runtime library, AppSync resolver templates now execute with real semantics rather than fixture responses.

🔐 IAM: cross-account assumed-role credentials

A meaningful identity improvement: assumed-role credentials now route to the target account (#1549). Multi-account testing patterns that rely on sts:AssumeRole to switch contexts now behave correctly, which unlocks more realistic enterprise-style IAM workflows.

🔄 State reset and nuke endpoints

floci-core gains state reset and nuke endpoints (#1482). Useful for CI suites that want a known-clean starting state without restarting the container, and for development workflows where wiping state mid-session is faster than a full restart.

🚢 ECS conformance pass

A coordinated ECS improvement set:

Task portMappings hostPort honored when launching containers (#1610)
Persisted model records registered for native-image reflection (#1606)
Idempotent ECS resource deletion on CloudFormation stack delete (#1645)

💾 Persistence improvements

Two notable persistence fixes:

Transcribe vocabularies now persist across restart (#1608)
Persisted state flushed before container teardown on shutdown (#1607)

The shutdown-flush fix is particularly important: it closes a small but real window where state changes immediately before shutdown could be lost.

🌐 ELBv2: resolvable local ALB DNS names

ALB DNS names are now resolvable locally (#1492). This addresses a common Terraform / SDK pattern where the ALB DNS name returned by DescribeLoadBalancers needs to actually resolve for the next test step to connect.
