What is CircleCI?

CircleCI's SSH reruns now open from the browser, through one trusted address.

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

What is ESPHome?

ESPHome's fourth 2026.11 beta tightens ESP8266 timing and BLE before release.

ESPHome is four betas into 2026.11. Beta 4 on November 12 locks interrupts more narrowly in ESP8266 software serial and IR transmission, sends BLE advertising as raw packets while keeping Improv in them, keeps bond keys on ESP-IDF 5.5.6, skips OTA authentication when the password is empty and stops MIPI DSI panels freezing during flash writes. Earlier betas fixed ESP32-P4 deep sleep and RTL8710B timers.

6.3

CircleCI's SSH reruns now open from the browser, through one trusted address.

◆ Current state

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

◆ Where it's heading

CircleCI is closing old paths (lenient config, v1 API fields, old Xcode images) while making failures easier to reach: job-linked commit statuses last week, browser SSH this week. The newer Functions beta and API v3 are where users are being steered.

◆ Prediction

Expect more debug tools on the job page and further v1 API removals pointing users to v3 before year end.

5.0

ESPHome's fourth 2026.11 beta tightens ESP8266 timing and BLE before release.

◆ Current state

ESPHome is four betas into 2026.11. Beta 4 on November 12 locks interrupts more narrowly in ESP8266 software serial and IR transmission, sends BLE advertising as raw packets while keeping Improv in them, keeps bond keys on ESP-IDF 5.5.6, skips OTA authentication when the password is empty and stops MIPI DSI panels freezing during flash writes. Earlier betas fixed ESP32-P4 deep sleep and RTL8710B timers.

◆ Where it's heading

The project keeps its monthly train: weekly betas of chip-specific fixes and footprint trims, then a release around the third week. This cycle's attention is on low-level timing on ESP8266 and RTL8710B and on Bluetooth reliability.

◆ Prediction

Expect one more beta at most and 2026.11.0 around November 18-20.
