v1.1.0 - HCL Terraform parsing + dependency bumps Latest
Latest

What changed

Bug fixes

  • Native HCL Terraform parsing. Uploads of .tf files were silently dropped before reaching the model — the parser only handled Terraform's JSON syntax and threw on HCL. We now use @cdktf/hcl2json for HCL with a JSON fallback for .tf.json. Any infrastructure file where the structured parser produces zero resources also falls back to a raw-content path so the model still sees the source. Body is capped at 200KB to protect the prompt budget.

Dependency updates

  • uuid 9.0.1 → 14.0.0 (closes Dependabot PR #2). Requires Node 20+; both Dockerfiles already use node:20-alpine. @types/uuid removed since uuid v10+ ships its own types.
  • express 4.18.2 → 4.22.2 (transitively bumps qs 6.14 → 6.15.1, closes Dependabot PR #1).

v1.0.0 - Initial public release

First public release of the AWS Pricing Assistant — a sample reference architecture that helps customers estimate AWS costs through natural-language conversation.

What's in this release

  • Conversational pricing UX: Real-time chat with streaming responses, file upload (CloudFormation, Terraform, CDK), dark/light theme
  • Live AWS pricing data: Bedrock Converse API with inline tool use against the AWS Pricing API and Savings Plans API — no stale training data
  • Two Claude models: Default Claude Opus 4.6, optional Claude Sonnet 4.5 (both via cross-region inference profiles)
  • Production-ready architecture: Frontend + backend on ECS Fargate, internal ALB locked to the CloudFront prefix list, AWS WAF rate limiting, Bedrock Guardrails
  • Cost guardrails: AWS Budget hard cap with auto-attached deny IAM policy on breach
  • Optional authentication: Cognito user pool with admin-managed users (name attribute), FIDO2 passkeys via Amplify v6 (Touch ID, Windows Hello, YubiKey, etc.) with friendly names backed by DynamoDB, optional/mandatory TOTP MFA — flippable at runtime via the `AuthEnabled` CloudFormation parameter
  • GitOps deployment: 9-stack CloudFormation deployment driven by AWS CodePipeline
