pegboard vs varnish: at a glance
What is pegboard?
The Carpentries' lesson parser spends its releases keeping pace with tinkr underneath it.
pegboard reads and validates Carpentries lesson source, and its recent releases are dominated by tracking changes in tinkr, the Markdown layer it sits on. The 0.7.8 switch from yaml to frontmatter handling needed a hotfix three days later in 0.7.9; 0.7.6 was similarly a compatibility fix for a tinkr show argument change. The genuinely additive work — tabset panel support in 0.7.5, caution divs in 0.7.7 — is smaller and less frequent.
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.

The Carpentries' lesson parser spends its releases keeping pace with tinkr underneath it.
◆ Current state
pegboard reads and validates Carpentries lesson source, and its recent releases are dominated by tracking changes in tinkr, the Markdown layer it sits on. The 0.7.8 switch from yaml to frontmatter handling needed a hotfix three days later in 0.7.9; 0.7.6 was similarly a compatibility fix for a tinkr show argument change. The genuinely additive work — tabset panel support in 0.7.5, caution divs in 0.7.7 — is smaller and less frequent.
◆ Where it's heading
This is infrastructure whose roadmap is largely set by its dependency. Contributor churn is visible in the release notes, with several first-time contributors and the release role passing between maintainers, which suggests a community project maintained in bursts rather than to a plan. New lesson-authoring features arrive when someone contributes one, not on a cadence.
◆ Prediction
The next release will most likely be another tinkr compatibility pass or a small addition to the set of recognised div types, following the pattern of every release in this window.
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.
