What is Dovetail?

Dovetail is becoming an always-on research agent that works inside your existing tools

Dovetail has moved past its origins as a research repository. The recent batch centers on two pillars: Channels, which pulls scattered customer signal from support tools, CRMs, and now the data warehouse into one analysis layer, and Dovetail Agents, now generally available and grounded in that data. The product now positions itself as the layer that turns raw feedback into answers wherever teams already work.

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.

Dovetail is becoming an always-on research agent that works inside your existing tools

◆ Current state

Dovetail has moved past its origins as a research repository. The recent batch centers on two pillars: Channels, which pulls scattered customer signal from support tools, CRMs, and now the data warehouse into one analysis layer, and Dovetail Agents, now generally available and grounded in that data. The product now positions itself as the layer that turns raw feedback into answers wherever teams already work.

◆ Where it's heading

The direction is unmistakably agentic and connective. Nearly every release either widens the set of sources feeding Channels (ServiceNow, HubSpot tickets, Salesforce, Snowflake) or extends where Dovetail's AI can reach — MCP tool connections in chat, a Microsoft Copilot connector, per-project context to sharpen classification. Dovetail is competing to be the system of record for customer insight rather than a place researchers file notes.

◆ Prediction

Expect the Channels 2.0 beta to reach general availability and the integration list to keep growing toward parity across major CRMs and warehouses, with Agents shifting from chat-triggered answers toward more autonomous, scheduled workflows.

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.
