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.
What is OpenMQTTGateway?
OpenMQTTGateway returns after 22 months with a security-first 1.9.0.
OpenMQTTGateway shipped v1.9.0 on November 7, its first release since January 2025. It moves to the Arduino ESP32 core 3.x, ships Theengs Decoder 2.5.0 with a fix for a BLE advertisement parsing flaw affecting every earlier release, and hardens buffer handling across MQTT, HTTP, BLE and RF input. Upgrade notes warn that some Home Assistant unique_ids change and that encrypted BLE devices are skipped until a key is set.

Knock
5.0INFRA · APIS
Knock adds single-step test runs and retries for failed workflow runs.
◆ Current state
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.
◆ 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.
OpenMQTTGateway
2.5INFRA · APIS
OpenMQTTGateway returns after 22 months with a security-first 1.9.0.
◆ Current state
OpenMQTTGateway shipped v1.9.0 on November 7, its first release since January 2025. It moves to the Arduino ESP32 core 3.x, ships Theengs Decoder 2.5.0 with a fix for a BLE advertisement parsing flaw affecting every earlier release, and hardens buffer handling across MQTT, HTTP, BLE and RF input. Upgrade notes warn that some Home Assistant unique_ids change and that encrypted BLE devices are skipped until a key is set.
◆ Where it's heading
Earlier releases made the gateway independent of controllers and external brokers. The return release is about safety and a modern ESP32 base rather than new features, which suggests the project is resetting its foundation before resuming feature work.
◆ Prediction
Expect the promised security advisory for the Theengs Decoder flaw and 1.9.x fixes for the Home Assistant entity changes; whether regular cadence resumes is not yet clear from the entries.
