What is Weblate?

Weblate 2026.11.2 speeds up stats and moves minor security issues into the open.

Weblate ships a monthly feature release and point releases after it. 2026.11 made built-in roles editable and widened Workspaces, and 2026.11.1 added account security findings with leaked-password checks. 2026.11.2 on November 12 adds a setting for default workspace translation-memory use, faster category statistics and translation propagation, and changes the security policy so low and medium issues are handled in public on GitHub.

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

Weblate 2026.11.2 speeds up stats and moves minor security issues into the open.

◆ Current state

Weblate ships a monthly feature release and point releases after it. 2026.11 made built-in roles editable and widened Workspaces, and 2026.11.1 added account security findings with leaked-password checks. 2026.11.2 on November 12 adds a setting for default workspace translation-memory use, faster category statistics and translation propagation, and changes the security policy so low and medium issues are handled in public on GitHub.

◆ Where it's heading

Recent releases have pushed Weblate toward large hosted and enterprise installs: workspaces, identity-provider team sync, editable roles and now admin security tooling. Performance work targets installations with many users and projects.

◆ Prediction

2026.12 is likely to extend Workspaces and Automation further, with a point release about a week later.

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.
