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 Umbrel?

umbrelOS 2.1 beta edits Office files in Files and adds Android and Windows apps.

umbrelOS 2.0 went final on September 22 with Photos, iPhone and Mac apps, Machines, multiple users, an MCP server and FailSafe RAID, and 2.0.1 patched a kernel network CVE on November 1. Three days later the 2.1 Beta 1 opened the next line: a Files viewer that opens and edits PDFs, Word, PowerPoint and Excel files, Umbrel apps for Android and Windows, and bridged networking, USB devices and a shared clipboard for Machines. umbrelOS now also fits phones and tablets.

7.5

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

umbrelOS 2.1 beta edits Office files in Files and adds Android and Windows apps.

◆ Current state

umbrelOS 2.0 went final on September 22 with Photos, iPhone and Mac apps, Machines, multiple users, an MCP server and FailSafe RAID, and 2.0.1 patched a kernel network CVE on November 1. Three days later the 2.1 Beta 1 opened the next line: a Files viewer that opens and edits PDFs, Word, PowerPoint and Excel files, Umbrel apps for Android and Windows, and bridged networking, USB devices and a shared clipboard for Machines. umbrelOS now also fits phones and tablets.

◆ Where it's heading

Each release moves Umbrel further from a box that runs self-hosted apps toward a personal cloud that replaces everyday services: photo backup, file access from every desktop OS, document editing, and virtual machines that behave like real computers on the home network. The companion apps now cover iPhone, Mac, Android and Windows.

◆ Prediction

The 2.1 line will likely take one or two more betas before a stable release, following the 2.0 pattern of two betas then a final. Raspberry Pi devices still lack a patched kernel for the 2.0.1 CVE, so a follow-up fix for them is also likely.
