## Executive Summary (TL;DR)
dbt Core v1.11.13. Source highlight: dbt-core 1.11.13 - August 12, 2026

## New Features
- Warn users if they are using a deprecated dbt version (#15964)

## Bug Fixes
- Fix intermittent "references a model that does not exist" parsing error when unit testing versioned models, caused by non-deterministic filesystem parse order (#11139)
- Fix partial parsing ghost-duplicate that raised a false "found two data_tests" error by cleaning up disabled generic and singular test nodes on schema re-parse (#)
- 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)
- Bump ca-certificates, libpq-dev, and openssh-client in Docker image to current bullseye versions to fix Docker release build failure caused by superseded package versions (#NA)
