What is contagionchannels?

Three releases in ten days, every one of them a CRAN reviewer's correction rather than a code change.

contagionchannels reached CRAN on 2026-05-08 with a methodology preprint behind it and a cross-quantilogram lineage visible in its citations. What the release feed does not contain is any description of what the package computes: all three entries document the submission process — a licence field reduced from GPL-3 plus file to plain GPL-3, an arXiv reference rewritten in canonical DOI form, and a base-graphics fallback adjusted on a reviewer's request.

What is q2?

After two releases pulling ahead, q2 spends v0.23.0 back on parity: light/dark theming.

q2 is the Quarto team's Rust reimplementation of the publishing toolchain, shipping as a statically linked single binary with minisign-signed archives and a bundled Quarto Hub MCP server, still marked experimental and not production-ready. The cadence holds at roughly a release a day through mid-August, with raw commit logs standing in for curated notes. v0.22.0 was the break in the pattern — llms.txt site output and a live-share preview, the first capability the original toolchain does not have. v0.23.0 goes straight back to closing the parity gap, and does it at epic scale.

Three releases in ten days, every one of them a CRAN reviewer's correction rather than a code change.

◆ Current state

contagionchannels reached CRAN on 2026-05-08 with a methodology preprint behind it and a cross-quantilogram lineage visible in its citations. What the release feed does not contain is any description of what the package computes: all three entries document the submission process — a licence field reduced from GPL-3 plus file to plain GPL-3, an arXiv reference rewritten in canonical DOI form, and a base-graphics fallback adjusted on a reviewer's request.

◆ Where it's heading

There is no product trajectory to read here yet, only a submission one, and it is unusually well documented — each entry names the reviewer or check that prompted it and quotes the feedback verbatim. That transparency is the one signal available: the maintainer treats review rounds as releases worth publishing rather than squashing. Any judgement about direction will have to wait for a release that changes the package rather than its metadata.

◆ Prediction

With CRAN acceptance secured, the next release should be the first to carry actual methodological content; until one appears, there is not enough in these entries to say where the package is heading.

6.3

After two releases pulling ahead, q2 spends v0.23.0 back on parity: light/dark theming.

◆ Current state

q2 is the Quarto team's Rust reimplementation of the publishing toolchain, shipping as a statically linked single binary with minisign-signed archives and a bundled Quarto Hub MCP server, still marked experimental and not production-ready. The cadence holds at roughly a release a day through mid-August, with raw commit logs standing in for curated notes. v0.22.0 was the break in the pattern — llms.txt site output and a live-share preview, the first capability the original toolchain does not have. v0.23.0 goes straight back to closing the parity gap, and does it at epic scale.

◆ Where it's heading

The light-dark epic is the shape of how this team retires a Quarto 1 feature: a design doc, then ThemeConfig growing a parsed dark variant, dual theme compilation with color-scheme emission, attributed stylesheet links, a color-mode toggle runtime, an accessibility-aware highlight-style reader, a brand light/dark seam, and an end-to-end verification pass against quarto-web before the docs land. One phase (D) was deferred with its options recorded rather than dropped. Around it, panel-tabset support lands, format.html.css is finally copied and rebased per page, and the llms companion output gains a link-format attribute so authors control where companion links point — the one thread tying this release back to the v0.22.0 work.

◆ Prediction

Expect the remaining Q1 parity items to keep setting the release agenda, with the deferred light-dark phase D and the freshly opened panel-tabset plan the two named strands most likely to fill the next few tags. npx distribution for the standalone Quarto Hub MCP bundle is still the only distribution item the notes explicitly call planned.
