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 ESPHome?

ESPHome 2026.10.1 follows the .0 by six days with OTA, MQTT and codegen fixes.

ESPHome shipped 2026.10.1 on Oct 27, six days after 2026.10.0. The patch keeps the OTA watchdog timeout on ESP32 hosted coprocessors, resends a fan's MQTT state when the first publish fails, fixes generated C++ for infinite floats, and handles version-less library dependencies the way PlatformIO does. 2026.10.0 itself rolled up six betas of ESP-IDF 6.1 groundwork, audio tuning and RAM savings.

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.

ESPHome 2026.10.1 follows the .0 by six days with OTA, MQTT and codegen fixes.

◆ Current state

ESPHome shipped 2026.10.1 on Oct 27, six days after 2026.10.0. The patch keeps the OTA watchdog timeout on ESP32 hosted coprocessors, resends a fan's MQTT state when the first publish fails, fixes generated C++ for infinite floats, and handles version-less library dependencies the way PlatformIO does. 2026.10.0 itself rolled up six betas of ESP-IDF 6.1 groundwork, audio tuning and RAM savings.

◆ Where it's heading

The monthly train is predictable: about three weeks of betas, a .0, then a .1 patch within two weeks. The focus this cycle was memory footprint on constrained chips and preparing for ESP-IDF 6.1, and the .1 is cleanup of codegen and build edge cases.

◆ Prediction

Expect the 2026.11 betas to start in early November, likely carrying more ESP-IDF 6.1 migration, and possibly a 2026.10.2 if more regressions surface.
