What is Chromatic?

Chromatic opens a beta that lets coding agents read and fix visual test failures.

Chromatic spent 2026 moving beyond Storybook: Vitest Browser Mode launched in September and React Native visual testing on cloud iOS and Android devices was announced in October. On November 5 it opened Chromatic for agents in beta, where a coding agent reads the test results, fixes the regressions and repeats until the pull request is ready.

What is runc?

runc patches one restore bug across four release lines at once.

runc shipped 1.5.3, 1.4.4, 1.3.7 and 1.6.0-rc.2 on the same day, all fixing CVE-2026-119101: a crafted image could make runc restore bind-mount any host directory into a restored container, read-write. Only people who checkpoint and later restore untrusted containers as root are exposed. The 1.6.0 candidate also changes how mount destinations that start with the rootfs path are read, following the runtime spec literally.

Chromatic opens a beta that lets coding agents read and fix visual test failures.

◆ Current state

Chromatic spent 2026 moving beyond Storybook: Vitest Browser Mode launched in September and React Native visual testing on cloud iOS and Android devices was announced in October. On November 5 it opened Chromatic for agents in beta, where a coding agent reads the test results, fixes the regressions and repeats until the pull request is ready.

◆ Where it's heading

Chromatic is turning from a review screen for humans into a feedback loop that coding agents can act on. Each new entry point (Vitest, React Native, now agents) widens who and what sends work through its visual tests.

◆ Prediction

The beta post is brief, so how agents connect is unclear; expect a follow-up naming the supported agents and moving this toward general availability.

5.0

runc patches one restore bug across four release lines at once.

◆ Current state

runc shipped 1.5.3, 1.4.4, 1.3.7 and 1.6.0-rc.2 on the same day, all fixing CVE-2026-119101: a crafted image could make runc restore bind-mount any host directory into a restored container, read-write. Only people who checkpoint and later restore untrusted containers as root are exposed. The 1.6.0 candidate also changes how mount destinations that start with the rootfs path are read, following the runtime spec literally.

◆ Where it's heading

The project now maintains four supported branches and backports security work to each one in lockstep, while 1.6.0 keeps trading quiet tolerance for strict spec behaviour: refused read-only configs in rc.1, literal mount paths in rc.2. Users relying on runc's old lenient handling will feel 1.6.0 more than any feature it adds.

◆ Prediction

Expect 1.6.0 final after one more candidate, with 1.3.z ending since 1.3.7 is labelled the probable last patch.
