What is projoint?

projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.

projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.

What is Quay?

Quay ships nothing but CVE remediation, mirrored across two supported branches

Every entry in Quay's recent history is a security maintenance release, and they arrive as coordinated pairs — a 3.10.x and a 3.12.x tag cut hours apart carrying the same fixes cherry-picked to each branch. The content is dependency remediation against tracked advisories plus two SSRF hardening fixes, one in proxy cache upstream registry configuration and one in repository mirroring sources. No feature work appears in the window.

projoint spent a year on CRAN paperwork, then shipped a correctness fix it flagged itself.

◆ Current state

projoint is an R package for analysing conjoint survey experiments, covering Qualtrics import, reshaping, and quantity-of-interest estimation with inter-rater reliability correction. Most of its release history is CRAN admission work — citation formats, DESCRIPTION fields, \value{} tags, vignette cleanups — with four tags backfilled within ninety seconds of each other on 15 July in non-monotonic version order, so neither tag order nor timestamps in this feed track the real sequence. The substantive releases are the ones fixing data-preparation bugs that silently corrupt estimates.

◆ Where it's heading

The maintainer is hardening the path from raw Qualtrics export to estimate, which is where conjoint analysis quietly goes wrong. Three separate releases fix that path: dropped respondent-level weights in organize_data(), repeated-task reshaping in reshape_projoint(), and choice-to-profile mapping in 1.1.3. Each fix now arrives with regression tests and stricter validation rather than just a patch, and 1.1.3 adds an explicit .choice_map so the mapping is auditable instead of inferred.

◆ Prediction

Expect the validation-and-regression-test pattern to keep extending across the import path, with releases continuing to arrive in bursts around CRAN submission rather than on a cadence.

Quay ships nothing but CVE remediation, mirrored across two supported branches

◆ Current state

Every entry in Quay's recent history is a security maintenance release, and they arrive as coordinated pairs — a 3.10.x and a 3.12.x tag cut hours apart carrying the same fixes cherry-picked to each branch. The content is dependency remediation against tracked advisories plus two SSRF hardening fixes, one in proxy cache upstream registry configuration and one in repository mirroring sources. No feature work appears in the window.

◆ Where it's heading

This is a registry in pure maintenance posture on its long-lived branches, with the release process itself automated down to changelog-bump commits. The recurring SSRF fixes across proxy cache and mirroring suggest a deliberate sweep through the code paths that fetch from upstream registries rather than isolated reports. Feature development, if it is happening, is landing on a branch this feed does not cover.

◆ Prediction

Expect the paired-branch cadence to continue at roughly the rate advisories land against the bundled Python and npm dependencies. The SSRF sweep looks close to complete, having now covered both proxy cache and mirroring.
