poppr vs varnish: at a glance
What is poppr?
A population-genetics workhorse in long-term maintenance, shipping only what CRAN demands.
poppr analyses populations with mixed clonal and sexual reproduction, and its recent history is almost entirely upkeep. Four of the last six releases state outright that they contain no user-visible changes — CRAN nit-picks, URL formatting, a clang13 build failure. The last release with real content was 2.9.0, which added bruvo.between() for comparing a query dataset against a reference database and began deprecating the blacklist argument in favour of exclude.
What is varnish?
The Carpentries' lesson skin, rebuilt on Bootstrap 5 with dark mode and a wider reach.
varnish supplies the HTML and CSS styling for Carpentries lessons. The defining release in this window is 1.0.3, which moved the theme to Bootstrap 5.3.2, implemented dark mode, made analytics configurable and taught the all-in-one search to distinguish learner from instructor views. Since then the work has been consolidation: dark-mode bugs, Sass variables for fonts, per-carpentry favicons, and fonts that render Ukrainian lessons.

poppr
0.0ANALYTICS
A population-genetics workhorse in long-term maintenance, shipping only what CRAN demands.
◆ Current state
poppr analyses populations with mixed clonal and sexual reproduction, and its recent history is almost entirely upkeep. Four of the last six releases state outright that they contain no user-visible changes — CRAN nit-picks, URL formatting, a clang13 build failure. The last release with real content was 2.9.0, which added bruvo.between() for comparing a query dataset against a reference database and began deprecating the blacklist argument in favour of exclude.
◆ Where it's heading
This is a mature package being kept installable rather than developed. The deprecation promised in 2.9.0 — removing blacklist in 2.10 — has not arrived across three years and four releases, which is the clearest sign that no feature line is currently active. What movement exists comes from outside contributors and from the toolchain moving underneath the package.
◆ Prediction
The next release is most likely another CRAN or compiler-compatibility fix; the promised 2.10 removal of blacklist would be the first sign of active development resuming, but nothing in these entries indicates it is being prepared.
varnish
0.0ANALYTICS
The Carpentries' lesson skin, rebuilt on Bootstrap 5 with dark mode and a wider reach.
◆ Current state
varnish supplies the HTML and CSS styling for Carpentries lessons. The defining release in this window is 1.0.3, which moved the theme to Bootstrap 5.3.2, implemented dark mode, made analytics configurable and taught the all-in-one search to distinguish learner from instructor views. Since then the work has been consolidation: dark-mode bugs, Sass variables for fonts, per-carpentry favicons, and fonts that render Ukrainian lessons.
◆ Where it's heading
The package is finishing a platform upgrade rather than starting something new — the Bootstrap 5 move created the dark-mode and CSS follow-ups that fill 1.0.4 and 1.0.5. It advances in lockstep with pegboard, the lesson parser: tabset panel support landed in both within a minute of each other, and the caution callout arrived the same way months later, so a new lesson element requires the pair to ship together. Contributors are numerous and largely first-time, so features track who shows up.
◆ Prediction
Expect further internationalisation and theming work — font and locale support is the one thread still opening rather than closing — most likely paired with a matching pegboard release if it touches lesson syntax.
