What is AWS?

AWS brings its OpenAI models into GovCloud on the same controls as every other Bedrock model.

The late-October run is led by GovCloud. OpenAI GPT-5.6 (Terra and Luna) reaches the bedrock-runtime endpoint there with Cross-Region Inference, Daybreak Red arrives in GovCloud (US-East) for enrolled customers, and Kiro web search lands in GovCloud with admin off-switches. The rest is operator detail: CloudFront viewer ISP and post-quantum TLS headers, optional minor version upgrades on RDS for Oracle options, and draft saving in Amazon Connect Customer.

What is Chromatic?

Chromatic for React Native takes visual tests to iOS simulators and Android emulators.

Chromatic for React Native, previewed in May, now has its own announcement: React Native Storybook stories become visual tests that run in parallel on cloud iOS simulators and Android emulators. It follows October's automatic reviewer assignment and combined Library view, and September's flaky-test quarantine and Vitest Browser Mode launch.

AWS brings its OpenAI models into GovCloud on the same controls as every other Bedrock model.

◆ Current state

The late-October run is led by GovCloud. OpenAI GPT-5.6 (Terra and Luna) reaches the bedrock-runtime endpoint there with Cross-Region Inference, Daybreak Red arrives in GovCloud (US-East) for enrolled customers, and Kiro web search lands in GovCloud with admin off-switches. The rest is operator detail: CloudFront viewer ISP and post-quantum TLS headers, optional minor version upgrades on RDS for Oracle options, and draft saving in Amazon Connect Customer.

◆ Where it's heading

The through-line is making third-party models behave like native AWS services. On bedrock-runtime, OpenAI usage shows up in Bedrock invocation logs, CloudWatch metrics and Cost Explorer, which is what regulated buyers need before approving a model. The same pattern shows on the agent side, where Kiro's web tools ship with organization-level and per-agent controls.

◆ Prediction

Expect more GovCloud parity notices for models and agent tools already available in commercial regions. The entries do not show which model is next.

Chromatic for React Native takes visual tests to iOS simulators and Android emulators.

◆ Current state

Chromatic for React Native, previewed in May, now has its own announcement: React Native Storybook stories become visual tests that run in parallel on cloud iOS simulators and Android emulators. It follows October's automatic reviewer assignment and combined Library view, and September's flaky-test quarantine and Vitest Browser Mode launch.

◆ Where it's heading

Chromatic spent the year making its visual test signal trustworthy and widening entry points beyond web Storybook, first to Vitest and now to mobile. Review routing and spend controls are arriving alongside for larger teams, so the product is being fitted to organizations that run many test surfaces at once.

◆ Prediction

Expect a monthly changelog to spell out React Native limits and billing, since the announcement states neither. Further review-routing and ownership work for large design systems is the other likely thread.
