highr vs RSelenium: at a glance
What is highr?
highr is finished software: one-line releases every year or two
highr does syntax highlighting for knitr output, and every release in this window is a single line of change. The most recent wraps hilight() output in xfun::raw_string() for nicer printing; before that, a rename of two LaTeX command macros and two bumps to the minimum R version. There is no feature work here at all.
What is RSelenium?
RSelenium's only release in eight years touched documentation and CI, nothing else.
1.7.10, published February 2026, contains documentation updates, a move from Travis CI to GitHub Actions, and CRAN note fixes — no functional change at all, and it is the first release since September 2018. The releases before it are equally quiet: a dummy argument in `executeScript`, `phantom()` made defunct, and credential-exposure and driver-startup fixes. The last real capability change in the window is `rsDriver()` arriving in 1.6.4, which replaced the defunct `checkForServer` and `startServer` helpers.

◆ Current state
highr does syntax highlighting for knitr output, and every release in this window is a single line of change. The most recent wraps hilight() output in xfun::raw_string() for nicer printing; before that, a rename of two LaTeX command macros and two bumps to the minimum R version. There is no feature work here at all.
◆ Where it's heading
This is a completed micro-package in the knitr ecosystem, maintained only to stay installable and consistent with its parent packages. Changes are triggered by knitr's needs or CRAN's requirements rather than by any plan of its own, and the gaps between releases run to years.
◆ Prediction
Expect the next release whenever knitr or CRAN requires one, with a similarly single-line changelog.

0.0INFRA · APIS
RSelenium's only release in eight years touched documentation and CI, nothing else.
◆ Current state
1.7.10, published February 2026, contains documentation updates, a move from Travis CI to GitHub Actions, and CRAN note fixes — no functional change at all, and it is the first release since September 2018.

The last real capability change in the window is `rsDriver()` arriving in 1.6.4, which replaced the defunct `checkForServer` and `startServer` helpers.
◆ Where it's heading
This is a package being kept installable rather than developed. The 2016-2018 era did the architectural work — moving process management out to wdman, recommending Docker for running a Selenium server, retiring PhantomJS — and nothing since has revisited it. That leaves RSelenium sitting on the older WebDriver arrangement while the browser-automation landscape has moved on.
◆ Prediction
Further releases, if any, are likely to be CRAN-compliance rather than feature work; the entries give no indication of active development resuming.
