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.

What is ESPEasy?

One release a year, each one a filesystem or networking rewrite you must plan for.

ESPEasy publishes rarely — five builds across two years — and each one accumulates hundreds of commits. The July 2026 mega build reworked how networking is handled and added support for Espressif's newer silicon: ESP32-P4, -C5 and C61. The 2025 build was the last to ship SPIFFS for ESP32, forcing a LittleFS conversion on everyone who upgrades past it. Release notes are raw commit lists grouped by contributor.

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.

One release a year, each one a filesystem or networking rewrite you must plan for.

◆ Current state

ESPEasy publishes rarely — five builds across two years — and each one accumulates hundreds of commits. The July 2026 mega build reworked how networking is handled and added support for Espressif's newer silicon: ESP32-P4, -C5 and C61. The 2025 build was the last to ship SPIFFS for ESP32, forcing a LittleFS conversion on everyone who upgrades past it. Release notes are raw commit lists grouped by contributor.

◆ Where it's heading

The project's pattern is long test cycles followed by a build that changes something foundational — filesystem, networking, MCU support — and asks users to back up settings before upgrading. Between those, only hotfixes appear. Development is heavily concentrated in one maintainer's commit stream, with the rest of the contributor list handling docs, build scripts and individual plugins.

◆ Prediction

Given the cadence, the next build is likely months out and shaped by whatever the current test-build issue accumulates; the newly added MCU families are the obvious place for follow-up plugin and peripheral work.
