tern vs USAboundaries: at a glance
What is tern?
tern is migrating its entire analysis-function catalogue off make_afun(), one release at a time.
tern builds the clinical-trial tables, listings, and graphs layer on top of rtables — occurrence counts, survival summaries, ANCOVA, incidence rates, subgroup and biomarker tabulations. The visible work across the window is a systematic refactor: dozens of analysis functions rewritten to drop make_afun() and adopt a common analysis-function style driven by rtables' additional_fun_params. Feature additions ride along with it.
What is USAboundaries?
Seven years dormant, then two releases dragging every census boundary from 2020 to 2024
USAboundaries supplies contemporary and historical US boundary data — states, counties, congressional districts, cities, ZIP code tabulation areas — as sf objects, with the bulk data held in a companion USAboundariesData package. After a gap running from 2018 to late 2025, two releases a month apart refreshed the contemporary census vintage from 2020 to 2024: 0.5.0 covered everything except states, and 0.5.1 finished the job.

◆ Current state
tern builds the clinical-trial tables, listings, and graphs layer on top of rtables — occurrence counts, survival summaries, ANCOVA, incidence rates, subgroup and biomarker tabulations. The visible work across the window is a systematic refactor: dozens of analysis functions rewritten to drop make_afun() and adopt a common analysis-function style driven by rtables' additional_fun_params. Feature additions ride along with it.
◆ Where it's heading
This is a multi-release architectural migration, not incremental polish. Each release converts another batch of functions, and the count is large — roughly two dozen in the most recent entry alone, after a comparable batch the release before. Alongside it, the denom parameter is being threaded through counting functions and g_lineplot is accumulating layout control, both patterns of standardising arguments that previously varied per function.
◆ Prediction
The refactor should continue until the make_afun() dependency is gone entirely, with the remaining tabulate_* and biomarker functions the likely next batch; the entries give no date for completion.

Seven years dormant, then two releases dragging every census boundary from 2020 to 2024
◆ Current state
USAboundaries supplies contemporary and historical US boundary data — states, counties, congressional districts, cities, ZIP code tabulation areas — as sf objects, with the bulk data held in a companion USAboundariesData package. After a gap running from 2018 to late 2025, two releases a month apart refreshed the contemporary census vintage from 2020 to 2024: 0.5.0 covered everything except states, and 0.5.1 finished the job.
◆ Where it's heading
For a data package the release cycle is the data vintage, and the 0.3.0 split into a separate data package was designed precisely so those refreshes would not require a code release. That the 2024 update still arrived as two package versions seven years later says the mechanism is being used sparingly. Nothing in the feed shows work on the API itself since us_cities() gained an sf return type and a states argument in 2018.
◆ Prediction
The next release is most likely another vintage refresh when the census data moves again, rather than new geographies or functions. The split of 0.5.0 and 0.5.1 suggests state boundaries are handled on a separate path from the rest and may lag again.
