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.

What is Coder?

Coder now patches three release lines at once, and the fixes keep landing on agent access.

Coder's feed shows patch releases on v2.29, v2.34 and v2.36 within three days, which means a v2.35 and a v2.36 mainline shipped that this feed never captured. The late-October fixes are permission work: new API keys stay within the caller's scopes, fetching external agent credentials now requires SSH permission, and read_skill_file reads are confined to the skill directory. Everything else is release-script and DERP client fixes.

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.

5.0

Coder now patches three release lines at once, and the fixes keep landing on agent access.

◆ Current state

Coder's feed shows patch releases on v2.29, v2.34 and v2.36 within three days, which means a v2.35 and a v2.36 mainline shipped that this feed never captured. The late-October fixes are permission work: new API keys stay within the caller's scopes, fetching external agent credentials now requires SSH permission, and read_skill_file reads are confined to the skill directory. Everything else is release-script and DERP client fixes.

◆ Where it's heading

The security surface is moving to the AI agent features. Two of the three substantive fixes this round concern what an agent can read or which credentials it can obtain, following the June hardening drop on OIDC linking and token theft. The multi-branch backporting continues, so enterprise customers on older lines like 2.29 still get the same permission fixes as the mainline.

◆ Prediction

Expect more permission checks around agent credentials and skills as those features get exercised; the feature releases themselves are not visible in this feed, so their direction is unclear from these entries.
