flightsbr vs varnish: at a glance
What is flightsbr?
Brazil's flight-data package keeps working around what ANAC publishes and when.
flightsbr downloads Brazilian civil aviation data — flights, airport movements, aircraft registrations, air fares — straight from ANAC into R. Its read_ functions now default to the latest available date rather than requiring one, and read_aircrafts() has been renamed to read_aircraft(). The published feed jumps from 0.1.2 to 0.3.0 to 1.1.0, so intermediate releases are not visible here.
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.

Brazil's flight-data package keeps working around what ANAC publishes and when.
◆ Current state
flightsbr downloads Brazilian civil aviation data — flights, airport movements, aircraft registrations, air fares — straight from ANAC into R. Its read_ functions now default to the latest available date rather than requiring one, and read_aircrafts() has been renamed to read_aircraft(). The published feed jumps from 0.1.2 to 0.3.0 to 1.1.0, so intermediate releases are not visible here.
◆ Where it's heading
This is a package defined by its upstream. Its releases are mostly reactions to how ANAC serves data: a download path that broke on 2022 data, URLs with inconsistent .CSV casing that hid available dates, a broken data dictionary link, and an air fares reader that had to be pulled entirely when the source became unworkable. The 2025 release is the first that reads like product design rather than repair — defaulting to the latest data and fixing a typo in a function name at the cost of a deprecation. Availability of the source, not developer intent, sets the release cadence.
◆ Prediction
The most likely next move is another adjustment to a changed ANAC endpoint or the return of the suspended air fares reader, since upstream availability has driven every release visible here.
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.
