What is Displayr?

Chat is being made legible while the survey-analysis core picks up the fundamentals it lacked.

Displayr is shipping on two fronts at a steady, unhurried cadence. The AI assistant is being made auditable rather than more capable — a context pill showing exactly what a prompt will send, a change summary listing every item Chat added, edited or deleted, and an Explain This button that routes errors and warnings into Chat with context attached. Separately the document core is filling in fundamentals: controls that stay synced across pages and page masters, rolling averages computed on date-keyed tables, browser-style back and forward navigation, and templates that can be saved as folder-scoped defaults.

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.

Chat is being made legible while the survey-analysis core picks up the fundamentals it lacked.

◆ Current state

Displayr is shipping on two fronts at a steady, unhurried cadence. The AI assistant is being made auditable rather than more capable — a context pill showing exactly what a prompt will send, a change summary listing every item Chat added, edited or deleted, and an Explain This button that routes errors and warnings into Chat with context attached. Separately the document core is filling in fundamentals: controls that stay synced across pages and page masters, rolling averages computed on date-keyed tables, browser-style back and forward navigation, and templates that can be saved as folder-scoped defaults.

◆ Where it's heading

The Chat work reads as a deliberate answer to the trust problem with AI in analyst tools — every release makes what the assistant touched inspectable rather than expanding what it can do unprompted. The other track is closing gaps a long-standing survey analysis platform accumulates, with the default-template mechanic notable for scoping defaults by Cloud Drive folder, which turns a personal preference into an organizational standard. Neither track has produced a directional move in this window.

◆ Prediction

Expect the transparency pattern to extend to Chat actions that modify data rather than layout, since the change summary establishes the mechanism. Folder-scoped defaults look like the start of broader template governance.

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.
