dbt Core vs timbr: at a glance
What is dbt Core?
dbt Fusion's second beta is adapter work: ClickHouse gets materializations, indexes, and catalogs
Fusion 2.0 is in its second beta, and the content has shifted from engine capability to adapter coverage. beta.2 is almost entirely ClickHouse — Dictionary materialization, index definitions, additional settings, a relation-scoped catalog macro that fixes --write-catalog, and a seed nullability fix — plus Entra bearer-token authentication for the Fabric adapter. Behind it sits the August 14 backport wave, which cut releases for 1.1 through 1.8 in a single day to deliver one deprecated-version warning.
What is timbr?
Three years dormant, timbr returns with dplyr verbs that finally respect tree structure
timbr provides a 'forest' class for nested tree data in R, letting users navigate parent/child relationships with tidyverse-style verbs. After its last release in May 2023, the package sat untouched for over three years before 0.3.0 landed in July 2026. That release is dominated by correctness work on the structural invariants that everything else depends on.

dbt Fusion's second beta is adapter work: ClickHouse gets materializations, indexes, and catalogs
◆ Current state
Fusion 2.0 is in its second beta, and the content has shifted from engine capability to adapter coverage. beta.2 is almost entirely ClickHouse — Dictionary materialization, index definitions, additional settings, a relation-scoped catalog macro that fixes --write-catalog, and a seed nullability fix — plus Entra bearer-token authentication for the Fabric adapter. Behind it sits the August 14 backport wave, which cut releases for 1.1 through 1.8 in a single day to deliver one deprecated-version warning.
◆ Where it's heading
The two ends of this project are pulling apart cleanly. Old branches are being prepared for retirement — a deprecation warning fanned across eight of them, Python 3.8 testing dropped from 1.4 through 1.6 — while Fusion accumulates the adapter breadth it needs to be a credible replacement. beta.1 proved the engine could bind without a catalog; beta.2 is the unglamorous follow-through of making a specific warehouse work properly.
◆ Prediction
Expect further beta releases filling in per-adapter gaps rather than new engine capability, and formal end-of-life notices for the branches that just took the deprecation warning.

Three years dormant, timbr returns with dplyr verbs that finally respect tree structure
◆ Current state
timbr provides a 'forest' class for nested tree data in R, letting users navigate parent/child relationships with tidyverse-style verbs. After its last release in May 2023, the package sat untouched for over three years before 0.3.0 landed in July 2026. That release is dominated by correctness work on the structural invariants that everything else depends on.
◆ Where it's heading
The arc is from a working prototype toward a class that behaves correctly under the full dplyr surface. 0.3.0 implements relocate(), rows_patch() and rows_update() for forests and makes select() always preserve the internal node column, closing the gaps where a standard verb would silently break the tree. The deprecation of map_forest() in favour of traverse(), begun in 0.2.2, is now complete.
◆ Prediction
With the verb coverage gaps closed and the long deprecation cycle finished, the next release is likely to extend dplyr method coverage further rather than change the forest model. The entries do not indicate what prompted the three-year gap, so the sustainability of this cadence is unclear.
