poissonreg vs USAboundaries: at a glance
What is poissonreg?
poissonreg gave its models away to parsnip and kept the glue — now it just keeps glmnet honest.
poissonreg is a tidymodels extension that wires Poisson and zero-inflated count regression into the parsnip interface. Its defining event was giving up ownership: the model definition functions moved into parsnip itself, leaving this package as engine bindings and prediction plumbing. The current dev release is entirely correctness and hygiene work — glmnet predictions now default to mean counts rather than the linear predictor, and single-observation prediction works at last.
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
poissonreg is a tidymodels extension that wires Poisson and zero-inflated count regression into the parsnip interface. Its defining event was giving up ownership: the model definition functions moved into parsnip itself, leaving this package as engine bindings and prediction plumbing. The current dev release is entirely correctness and hygiene work — glmnet predictions now default to mean counts rather than the linear predictor, and single-observation prediction works at last.
◆ Where it's heading
Release cadence has collapsed from yearly to a four-year gap between 1.0.1 and the current development version, and the content has shifted from features to deduplication against parsnip — copied helper functions replaced by the upstream originals, obsolete generic registrations removed, tests migrated to the shared extension-package pattern. This is what a stabilized tidymodels satellite looks like: the interface lives upstream, and the package's job is to not drift from it.
◆ Prediction
The dev version's accumulated fixes point to a CRAN release of 1.0.2 as the next move, with content limited to the glmnet prediction corrections rather than any new engine or model type.

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.
