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.

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.

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.

2.5

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.
