What is quarto?

Quarto's VS Code extension moved to MIT and now ships fixes for Positron and citations.

Quarto's VS Code extension ships roughly monthly with a focus on cell editing and Positron integration. After the MIT relicense in 1.137.0, 1.138.0 fixed how Python cells run in knitr documents in Positron, a language-server crash on bad YAML options, and Zotero failing to appear as a citation source. 1.139.0 in October raised the minimum VS Code version and fixed citation and YAML handling.

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.

Quarto's VS Code extension moved to MIT and now ships fixes for Positron and citations.

◆ Current state

Quarto's VS Code extension ships roughly monthly with a focus on cell editing and Positron integration. After the MIT relicense in 1.137.0, 1.138.0 fixed how Python cells run in knitr documents in Positron, a language-server crash on bad YAML options, and Zotero failing to appear as a citation source. 1.139.0 in October raised the minimum VS Code version and fixed citation and YAML handling.

◆ Where it's heading

Since the relicense, releases have been fixes rather than features, mostly around Positron and the visual editor's citation support. The extension increasingly defers language features to Positron when it provides them.

◆ Prediction

Expect a 1.140 release within about a month with more Positron integration fixes; no new feature area is signalled.

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.
