dbt Core v2.0.0-dev.41-test-pypi. Source highlight: Released September 23, 2026

## New Features
- Add PyPI banner for dbt-oss mirroring the existing dbt-core banner, without the dbt-core namespace deprecation notice

## Bug Fixes
- [Lake Compute] Read AWS Databricks Unity Catalog tables using Databricks profile PAT/OAuth M2M credentials, declaration-aware validation, and `dbt debug` attach parity. Existing fs `catalogs.yml` entries continue to use `type: unity`. Existing local Unity attach options in `config.lakecompute` must move to `config.duckdb`; Lake Compute access is read-only and Unity model writes are unsupported.
- Fix modules.re functions silently dropping keyword arguments (flags=, maxsplit=, count=) (#15508)
- Emit only changed columns in Databricks column-tag alter diffs (#16246)
- Emit only changed keys in Databricks relation-tag SET TAGS diffs (#16248)
- Implement TableRepr methods index_of_value_in_column and count_occurrences_of_value_in_column to fix Fusion panic in dbt_utils.get_query_results_as_dict()
- Copy config.group onto the top-level group for source and singular tests, matching dbt-core (#15930)
