Release Notes

August 2026

Migrates the union_connections, apply_source_relation, and partition_by_source_relation macros to the dbt_fivetran_utils package.
Adds the fivetran_using_source_casing variable for case-sensitive destination support. When enabled, downstream transformations respect source casing to ensure consistent results. See the Additional Configurations section of the README for details.

In the quickstart.yml file:
- Adds table_variables for relevant sources to prevent missing sources from blocking downstream Quickstart models.

Union Data Functionality: This release supports running the package on multiple GitHub source connections. See the README for details on how to leverage this feature.

Removes uniqueness tests. The new unioning feature requires combination-of-column tests to consider the new source_relation column in addition to the existing primary key, but this is not supported across dbt versions.
- These tests will be reintroduced once a version-agnostic solution is available.

Removed the dependency on the fivetran/github_source package.
- All functionality from the source package has been merged into this transformation package for improved maintainability and clarity.
- If you reference fivetran/github_source in your packages.yml, you must remove this dependency to avoid conflicts.
- Any source overrides referencing the fivetran/github_source package will also need to be removed or updated to reference this package.
- Update any github_source-scoped variables to be scoped to only under this package. See the README for how to configure the build schema of staging models.
As part of the consolidation, vars are no longer used to reference staging models, and only sources are represented by vars. Staging models are now referenced directly with ref() in downstream models.

Updated package to maintain compatibility with dbt-core versions both before and after v1.10.6, which introduced a breaking change to multi-argument test syntax (e.g., unique_combination_of_columns).
Temporarily removed unsupported tests to avoid errors and ensure smoother upgrades across different dbt-core versions. These tests will be reintroduced once a safe migration path is available.
- Removed all dbt_utils.unique_combination_of_columns tests.
- Moved loaded_at_field: _fivetran_synced under the config: block in src_github.yml.
