What is dbt Core?

dbt keeps three maintenance branches alive while Fusion 2.0 crosses into beta.

dbt-core is running two lines at once: a Python 1.x maintenance train across 1.10, 1.11 and 1.12, and the Rust Fusion 2.0 rewrite now in its first beta. The August 12 batch pushed the same deprecated-version warning into all three maintenance branches on one day, with the substantive work isolated to 1.12.1 (OpenTelemetry spans for node and hook execution) and 1.11.13 (deterministic unit-test resolution). Fusion is where the capability surface is actually widening.

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.

dbt keeps three maintenance branches alive while Fusion 2.0 crosses into beta.

◆ Current state

dbt-core is running two lines at once: a Python 1.x maintenance train across 1.10, 1.11 and 1.12, and the Rust Fusion 2.0 rewrite now in its first beta. The August 12 batch pushed the same deprecated-version warning into all three maintenance branches on one day, with the substantive work isolated to 1.12.1 (OpenTelemetry spans for node and hook execution) and 1.11.13 (deterministic unit-test resolution). Fusion is where the capability surface is actually widening.

◆ Where it's heading

The 1.x branches are converging on housekeeping — deprecation warnings, jsonschema definitions synced down from Fusion, parse-order determinism, adapter config recognition. That is the signature of a codebase being held stable rather than extended. Fusion 2.0 is absorbing the new work: catalog-free binding, a lint rule engine, node selection for lint and format, a self-hostable docs server.

◆ Prediction

Expect the maintenance branches to keep taking cross-branch warnings and adapter-config fixes while Fusion moves through further betas. The OpenTelemetry work in 1.12.1 is flag-gated behind --snowflake-projects-otel, which suggests tracing arrives unflagged in a later release.

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.
