Improvement1.12.1

dbt-core v1.12.1

This release includes OpenTelemetry span instrumentation for node and hook execution, fixes for inflated node counts in unit test selection, eager resolution issues, and improvements to adapter macro handling in Fusion-generated manifests.

dbt-core 1.12.1 - August 12, 2026

Features

  • Add OpenTelemetry span instrumentation for node and hook execution, gated behind the --snowflake-projects-otel flag (off by default) (#11367)

Fixes

  • Fix dbt build node count ("X of Y") being inflated when unit tests are selected, by adding the unit test count to num_nodes exactly once instead of on every dequeue while run_count is still 0 (#11185)
  • Stop resolving a unit test's tested model eagerly at parse time; resolve it only in the single deterministic post-parse pass so resolution no longer depends on filesystem parse order at all (deeper fix for (#11139)
  • Re-parse adapter macros from the installed adapter package after loading a Fusion-generated manifest, ensuring the user's installed dbt- version is used instead of Fusion's compile-time bundled copy (#15527)
  • Fix OpenTelemetry hook spans: name them by hook and transaction phase, skip calls that run no hooks, and add node context and status. (#11367)

Dependencies

  • Bump dbt-core-experimental-parser to 2.0.0b1 lowerbound (#)
