What is CircleCI?

CircleCI Server 4.10.2 and 4.9.7 carry the eMudhra distrust to self-hosted installs.

CircleCI spent late October on two surfaces. In the cloud product, GitHub check runs now explain on-hold jobs and re-runs run as the person who clicked, and CLI 1.11 can script Slack notifications. On Oct 28, Server 4.10.2 and 4.9.7 stopped trusting the compromised eMudhra intermediates and fixed Details links, proxy-related 500s and a tracing crash loop. Vault is deprecated and will be unsupported in Server 5.0, with a script to migrate to Tink.

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.

CircleCI Server 4.10.2 and 4.9.7 carry the eMudhra distrust to self-hosted installs.

◆ Current state

CircleCI spent late October on two surfaces. In the cloud product, GitHub check runs now explain on-hold jobs and re-runs run as the person who clicked, and CLI 1.11 can script Slack notifications. On Oct 28, Server 4.10.2 and 4.9.7 stopped trusting the compromised eMudhra intermediates and fixed Details links, proxy-related 500s and a tracing crash loop. Vault is deprecated and will be unsupported in Server 5.0, with a script to migrate to Tink.

◆ Where it's heading

The platform keeps pulling identity and permission checks onto the real actor: scoped tokens, V3 OIDC claims and re-run attribution. The self-hosted line follows with its own permission and link repairs. Server 5.0 is taking shape as a breaking release, at least for secret storage.

◆ Prediction

Expect more Server 4.x patches ahead of 5.0, with Tink migration guidance repeated until Vault support ends.

5.0

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.
