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 Fluentd?

Fluentd's newest line spent its last release hardening the paths that accept untrusted data.

Two branches are live: 1.19.x carries features and 1.16.x takes occasional single-fix backports. The most recent 1.19.3 is a dense correctness release with a distinctly security-shaped batch — strict host validation for dynamic endpoints in out_http, size limits enforced on decompressed payloads in the buffer and HTTP input, strict path boundary validation for tags, and tightened default visibility for config, retry and debug information in the monitor agent.

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.

Fluentd's newest line spent its last release hardening the paths that accept untrusted data.

◆ Current state

Two branches are live: 1.19.x carries features and 1.16.x takes occasional single-fix backports. The most recent 1.19.3 is a dense correctness release with a distinctly security-shaped batch — strict host validation for dynamic endpoints in out_http, size limits enforced on decompressed payloads in the buffer and HTTP input, strict path boundary validation for tags, and tightened default visibility for config, retry and debug information in the monitor agent.

◆ Where it's heading

The feature work landed in 1.19.0 — zstd compression across buffer, out_file, out_forward and in_forward, chunk evacuation when the retry limit is hit, TLS 1.3 in out_http — and everything since has been reliability and input validation. That ordering makes sense for a log collector: the interesting failure modes are decompression bombs, path traversal through tag names, and sockets that never close, not missing features. Ruby 4.0 compatibility work is threaded through the recent releases.

◆ Prediction

Expect 1.19.x to keep shipping validation and socket-lifecycle fixes with Ruby 4.0 support consolidating, and 1.16.x to receive only isolated backports.
