chromote vs contagionchannels: at a glance
What is chromote?
chromote turned the browser itself into a pinned, downloadable dependency.
chromote drives headless Chrome from R over the DevTools Protocol and underpins the R screenshot and app-testing stack. The visible history is shaped almost entirely by Chrome's own changes: old headless mode removed, DevTools URLs moved, viewport APIs deprecated. Version 0.5.0 answered that by letting chromote fetch and pin specific Chrome builds itself.
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.

◆ Current state
chromote drives headless Chrome from R over the DevTools Protocol and underpins the R screenshot and app-testing stack. The visible history is shaped almost entirely by Chrome's own changes: old headless mode removed, DevTools URLs moved, viewport APIs deprecated. Version 0.5.0 answered that by letting chromote fetch and pin specific Chrome builds itself.
◆ Where it's heading
The package has moved from reacting to Chrome upgrades to controlling them. The 0.3.0 and 0.4.0 pair tracked the headless-mode transition by first adding an option and then flipping the default; 0.5.0 removed the need to track it at all by managing versioned binaries through Chrome for Testing. Alongside that, the session API keeps accumulating helpers that collapse multi-step DevTools call sequences, such as $go_to() and $set_viewport_size().
◆ Prediction
The version-management features shipped marked experimental, so the likely next step is stabilizing that API and extending the session helpers that wrap common DevTools sequences.

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.
