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 pkgdown?

pkgdown now generates llms.txt and a markdown copy of every documentation page

pkgdown builds the documentation sites for most R packages. The 2.1 line was about format and appearance - Quarto vignettes, a light and dark switch, self-hosted assets instead of CDN fetches. The 2.2 line changed audience: build_llm_docs() emits an llms.txt at the site root and a markdown version of every page, on by default.

chromote turned the browser itself into a pinned, downloadable dependency.

◆ 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.

pkgdown now generates llms.txt and a markdown copy of every documentation page

◆ Current state

pkgdown builds the documentation sites for most R packages. The 2.1 line was about format and appearance - Quarto vignettes, a light and dark switch, self-hosted assets instead of CDN fetches. The 2.2 line changed audience: build_llm_docs() emits an llms.txt at the site root and a markdown version of every page, on by default.

◆ Where it's heading

Two audiences are now being served from one build. Human-facing work continues in small increments - dark-mode plot filtering, new translations, a local http server so search works in preview - while the new machine-facing output is opt-out rather than opt-in. The default matters more than the feature: thousands of package sites will start emitting llms.txt without their maintainers choosing to.

◆ Prediction

Expect the markdown output to gain the same configuration surface the HTML has, and the llms.txt contents to get more selective as maintainers discover what ends up in it; a way to exclude individual pages is the obvious next request.
