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 Rhino?

Rhino's release line runs on release candidates, and 1.12 makes room for coding agents.

Rhino publishes only release candidates to this feed — every entry back to 1.9 is an -rc tag, with no final release ever appearing. The 1.12.0 candidate is the first in the window with user-visible substance: a `use` function that scaffolds an AGENTS.md file carrying Rhino-specific instructions, plus a `use` function for the CI template. The rest is maintenance: covr-based test coverage, e2e tests, Node dependency updates, and a maintainer handover.

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.

Rhino's release line runs on release candidates, and 1.12 makes room for coding agents.

◆ Current state

Rhino publishes only release candidates to this feed — every entry back to 1.9 is an -rc tag, with no final release ever appearing. The 1.12.0 candidate is the first in the window with user-visible substance: a `use` function that scaffolds an AGENTS.md file carrying Rhino-specific instructions, plus a `use` function for the CI template. The rest is maintenance: covr-based test coverage, e2e tests, Node dependency updates, and a maintainer handover.

◆ Where it's heading

Rhino is converging on scaffolding as its main surface — the framework's value is increasingly in what it generates for you rather than what it does at runtime, and 1.12 extends that generation to instructions meant for AI coding agents rather than humans. The maintainer change and the CI/coverage work in the same release read as consolidation after a long gap: 1.11 shipped in April 2025, 1.12 not until June 2026.

◆ Prediction

More `use_*` scaffolding functions are the obvious next increment, since two arrived in a single release. Whether the AGENTS.md instructions grow into deeper agent tooling is not something these entries settle.
