What is OpenMQTTGateway?

OpenMQTTGateway follows its 22-month comeback with a quick reboot-loop fix.

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.

What is Clair?

Clair 4.10 RC can read SBOMs to match Java vulnerabilities.

Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.

OpenMQTTGateway follows its 22-month comeback with a quick reboot-loop fix.

◆ 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.

Clair 4.10 RC can read SBOMs to match Java vulnerabilities.

◆ Current state

Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.

◆ Where it's heading

Since 4.8 Clair has moved from Red Hat's older OVAL data to VEX, and each release follows Red Hat's security data more closely. 4.10 adds SBOMs as an input, so Clair can match what an image's own manifest declares, not only what it finds on disk.

◆ Prediction

More 4.10 release candidates and then a final are likely; the long gap between releases suggests that could take weeks.
