## New Features
- Announce dbt v2 availability as an INFO message on `dbt --version`, with a link to the v2 install docs (#)

## Bug Fixes
- Relay the v2 (Fusion) parser's log output via --log-format otel instead of json-compat, dropping span noise, keeping fusion's error/warning codes, and fixing a latent bug where a stray fusion stderr line could abort the run under --warn-error (#)
- Bare wildcard FQN selectors (e.g. `-s "f_*"`) now match nested models regardless of subfolder depth (#)
- Fix cumulative metrics with an `input_metric` and a top-level `window` field (v2 metric spec) incorrectly failing to parse with a legacy nested-`type_params` error (#N/A)
- Fix compiled_code not persisted to manifest.json when using --use-v2-parser (#)
- Include `semantic_manifest.json` in the artifact set uploaded by `--upload-to-artifacts-ingest-api`, matching other run artifacts (#N/A)
- Validate that tarball package download locations stay within the dbt downloads directory (#)
