What is rstanarm?

rstanarm is community-maintained now, tracking Stan and lme4 rather than adding models.

2.32.2 is entirely infrastructure and dependency work: formula machinery migrated from lme4 to reformulas, `r_eff` no longer computed for loo by default, the Stan R packages repo replaced by R-Universe, rstantools adopted to fix build and export errors, and CRAN NOTE cleanups — contributed largely by four first-time contributors. 2.32.1 and 2.26.1 follow the same pattern, tracking rstan syntax and adding `posterior::as_draws()` support. The last release with substantive modelling content is 2.21.1, which changed how default priors are determined and flipped `autoscale` to FALSE outside default priors.

What is taxize?

taxize spends its releases absorbing other people's API changes, one dead source at a time.

The most recent work is migration: 0.10.0 replaced the deprecated Global Names Resolver functions with GNA equivalents (`gna_verifier`, `gna_parse`), rewrote `scrapenames` for the new API, and updated its rredlist usage to match that package's own v4 rewrite. 0.10.1 then tuned `gna_verifier`'s batch size to 50. The older entries in the window show the same shape from a different angle: `tnrs()` made defunct because the service died, COL dropped over rate limiting, NatureServe reworked for a new API, and a package-wide parameter rename to `sci` / `com` / `id` / `sci_com` / `sci_id`.

rstanarm is community-maintained now, tracking Stan and lme4 rather than adding models.

◆ Current state

2.32.2 is entirely infrastructure and dependency work: formula machinery migrated from lme4 to reformulas, `r_eff` no longer computed for loo by default, the Stan R packages repo replaced by R-Universe, rstantools adopted to fix build and export errors, and CRAN NOTE cleanups — contributed largely by four first-time contributors. 2.32.1 and 2.26.1 follow the same pattern, tracking rstan syntax and adding `posterior::as_draws()` support. The last release with substantive modelling content is 2.21.1, which changed how default priors are determined and flipped `autoscale` to FALSE outside default priors.

◆ Where it's heading

The package has moved from feature development into ecosystem maintenance, and the contributor list shows why it survives: outside developers keep it compiling against a moving Stan, lme4 and CRAN. The `as_draws()` support and the reformulas migration both point the same way — rstanarm increasingly consumes shared infrastructure (posterior, reformulas, rstantools) instead of carrying its own.

◆ Prediction

Expect the next release to track another upstream change — rstan, reformulas or CRAN policy — rather than add model families. The pre-fit model surface looks settled.

◆ Current state

The most recent work is migration: 0.10.0 replaced the deprecated Global Names Resolver functions with GNA equivalents (`gna_verifier`, `gna_parse`), rewrote `scrapenames` for the new API, and updated its rredlist usage to match that package's own v4 rewrite. 0.10.1 then tuned `gna_verifier`'s batch size to 50.

◆ Where it's heading

taxize's job is aggregating a dozen taxonomic databases, so most of its engineering is downstream of decisions it does not control — sources go away, endpoints change, rate limits appear. The visible trend is consolidation: fewer, better-maintained backends rather than broader coverage. Release cadence has thinned to roughly one a year, and the rredlist coupling means it now inherits that package's breaking changes too.

◆ Prediction

Expect the next release to track another upstream source change rather than add new databases; the deprecated-parameter aliases from the 0.9.97 rename are also overdue for removal.
