OctoPrint vs Clair: at a glance
What is OctoPrint?
OctoPrint 2.0 is on its seventh release candidate, still with no final date.
OctoPrint 2.0 makes serial one connector among several, including Moonraker and Bambu, and removes deprecated plugin APIs. Release candidates have arrived every few weeks since April: rc5 in August fixed config and schema regressions, and rc6 and rc7 in October carried only the standard warning that a candidate may need a manual downgrade.
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.
OctoPrint vs Clair: editorial side-by-side
OctoPrint
5.0INFRA · APIS
OctoPrint 2.0 is on its seventh release candidate, still with no final date.
◆ Current state
OctoPrint 2.0 makes serial one connector among several, including Moonraker and Bambu, and removes deprecated plugin APIs. Release candidates have arrived every few weeks since April: rc5 in August fixed config and schema regressions, and rc6 and rc7 in October carried only the standard warning that a candidate may need a manual downgrade.
◆ Where it's heading
The 2.0 line is in a long stabilisation, with each candidate fixing regressions and asking testers to cover the new connectors. The thin notes on rc6 and rc7 suggest the remaining changes are small.
◆ Prediction
A 2.0.0 final is likely within a few candidates; the exact date is unclear from the entries.
Clair
2.5INFRA · APIS
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.
