+# dbt_sage_intacct_source v0.5.0
+
+[PR #23](https://github.com/fivetran/dbt_sage_intacct_source/pull/23) includes the following updates:
+
+## Breaking Change for dbt Core < 1.9.6
+
+> *Note: This is not relevant to Fivetran Quickstart users.*
+
+Migrated `freshness` from a top-level source property to a source `config` in alignment with [recent updates](https://github.com/dbt-labs/dbt-core/issues/11506) from dbt Core. This will resolve the following deprecation warning that users running dbt >= 1.9.6 may have received:
+
+```
+[WARNING]: Deprecated functionality
+Found `freshness` as a top-level property of `tiktok_ads` in file
+`models/src_tiktok_ads.yml`. The `freshness` top-level property should be moved
+into the `config` of `tiktok_ads`.
+```
+
+**IMPORTANT:** Users running dbt Core < 1.9.6 will not be able to utilize freshness tests in this release or any subsequent releases, as older versions of dbt will not recognize freshness as a source `config` and therefore not run the tests.
+
+If you are using dbt Core < 1.9.6 and want to continue running Sage Intacct freshness tests, please elect **one** of the following options:
+  1. (Recommended) Upgrade to dbt Core >= 1.9.6
+  2. Do not upgrade your installed version of the `sage_intacct_source` package. Pin your dependency on v0.4.1 in your `packages.yml` file.
+  3. Utilize a dbt [override](https://docs.getdbt.com/reference/resource-properties/overrides) to overwrite the package's `sage_intacct` source and apply freshness via the previous release top-level property route. This will require you to copy and paste the entirety of the previous release `src_sage_intacct.yml` file and add an `overrides: sage_intacct_source` property.

+## Under the Hood
+- Updates to ensure integration tests use latest version of dbt.

 - Materializes [Sage Intacct staging tables](https://fivetran.github.io/dbt_sage_intacct_source/#!/overview/sage_intacct_source/models/?g_v=1&g_e=seeds) which leverage data in the format described by [this ERD](https://fivetran.com/docs/applications/sage-intacct#schemainformation). These staging tables clean, test, and prepare your Sage Intacct data from [Fivetran's connector](https://fivetran.com/docs/applications/sage-intacct) for analysis by doing the following:
   - Names columns for consistency across all packages and for easier analysis
   - Adds freshness tests to source data
+    - dbt Core >= 1.9.6 is required to run freshness tests out of the box.
   - Adds column-level testing where applicable. For example, all primary keys are tested for uniqueness and non-null values.
 - Generates a comprehensive data dictionary of your sage_intacct data through the [dbt docs site](https://fivetran.github.io/dbt_sage_intacct_source/).
 - These tables are designed to work simultaneously with our [Sage Intacct transformation package](https://github.com/fivetran/dbt_sage_intacct).
