## Executive Summary (TL;DR)
dbt Core v1.12.4. Source highlight: dbt-core 1.12.4 - September 08, 2026

## New Features
- Add otel_trace_id() and otel_span_id() Jinja functions to correlate query comments and model SQL with OpenTelemetry trace/span ids (#)

## Bug Fixes
- Re-parse the built-in generic tests (test_not_null, test_unique, test_accepted_values, test_relationships) after loading a Fusion-generated manifest, so they are not permanently evicted and left undefined at test-compile time (#15914)
- Write target/manifest.json from the corrected in-memory manifest after loading a Fusion-generated manifest, so the on-disk artifact reflects the rediscovered adapter macros actually used for compilation instead of Fusion's raw bundled macros (#)
- Capture and re-emit fusion parser subprocess output through dbt-core's event system instead of letting it pass through to raw stdout/stderr, re-leveling each line by its json-compat severity when available (#15672)
- Validate that a resolved package installation path stays within the configured packages-install-path (#N/A)
