What is ESPHome?

ESPHome 2026.10.0 lands after six betas of audio, memory and ESP-IDF 6.1 work.

ESPHome shipped 2026.10.0 on Oct 21, two weeks after beta 1 and one beta more than 2026.9 needed. The release entry only links to the changelog. The betas show its content: ESP-IDF 6.1 groundwork, TAS58xx audio tuning, RAM savings on ESP8266, RP2040/RP2350 fixes, TCP-UART entities and an Intel Mac sunset notice.

What is Knock?

Knock adds single-step test runs and retries for failed workflow runs.

Knock is a notification infrastructure platform that spent September and October wiring itself into AI assistants (Claude, ChatGPT/Codex, Cursor) and Stripe Projects. Its latest two releases turn to the workflow debugger: a failed run can now be retried from where it stopped, and a single channel step can be tested in sandbox without running the whole workflow.

ESPHome vs Knock: editorial side-by-side

ESPHome

INFRA · APIS

5.0

ESPHome 2026.10.0 lands after six betas of audio, memory and ESP-IDF 6.1 work.

◆ Current state

◆ 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. Audio hardware support continues to grow each month.

◆ Prediction

Expect 2026.10.1 within two weeks with post-release fixes, and the 2026.11 betas to start in early November, likely carrying more ESP-IDF 6.1 migration.

Knock

INFRA · APIS

5.0

Knock adds single-step test runs and retries for failed workflow runs.

◆ Current state

◆ Where it's heading

With distribution through AI tools in place, Knock is now improving the day-to-day build-and-debug loop for workflows, following the September analytics tab. The pattern points to more operational tooling around runs, not new channels.

◆ Prediction

Expect further debugger and test-runner features, such as bulk retries or replays with edited data, given two debugging releases in three days.
