+# dbt_fivetran_log v1.6.0
+
+## Bug Fixes
+- It was observed that the `fivetran_platform__audit_table` model could potentially introduce duplicates for database like connectors. To address this issue, the join logic in the end model was adjusted to no longer be determined by date ranges and instead be defined via model generated indexes. This ensures true uniqueness in the end model.
+
+## Testing Updates
+- Addition of the `tests/` folder which includes various custom validation tests to ensure the the output of the end models are matching our expectations.
+  - These tests are disabled by default as they are not necessary to run after every execution of the models. If you would like to enabled these tests you may activate them by defining the `fivetran_validation_tests_enabled` variable as `true`.
+
+## Documentation Updates
+- Updated the incremental strategy documentation in the README to be more accurate.

 ### Database Incremental Strategies 
-Some of the end models in this package are materialized incrementally. We have chosen `insert_overwrite` as the default strategy for **BigQuery** and **Databricks** databases, as it is only available for these dbt adapters. For **Snowflake**, **Redshift**, and **Postgres** databases, we have chosen `delete+insert` as the default strategy.
+Many of the end models in this package are materialized incrementally, so we have configured our models to work with the different strategies available to each supported warehouse.
 
-`insert_overwrite` is our preferred incremental strategy because it will be able to properly handle updates to records that exist outside the immediate incremental window. That is, because it leverages partitions, `insert_overwrite` will appropriately update existing rows that have been changed upstream instead of inserting duplicates of them--all without requiring a full table scan.
+For **BigQuery** and **Databricks** destinations, we have chosen `insert_overwrite` as the default strategy, which benefits from the partitioning capability. 
 
-`delete+insert` is our second-choice as it resembles `insert_overwrite` but lacks partitions. This strategy works most of the time and appropriately handles incremental loads that do not contain changes to past records. However, if a past record has been updated and is outside of the incremental window, `delete+insert` will insert a duplicate record. 😱
-> Because of this, we highly recommend that **Snowflake**, **Redshift**, and **Postgres** users periodically run a `--full-refresh` to ensure a high level of data quality and remove any possible duplicates.

+## (Optional) Step 6: Run Model Validation Tests
+All end models in this package include a suite of singular validation tests located within the `tests/` folder of this project. These validation tests are designed to ensure the end models are matching the expected outcomes. By default these singular tests are not necessary to be executed after every `dbt run`; therefore, these tests are disabled by default. If you would like to run these tests as part of your own validation efforts you may define the `fivetran_validation_tests_enabled` variable as `true`.
+
+Further, all these singular validation tests utilize the `validations` tag. Therefore, if you would like to run these validation tests one-off you may run the following command to run **only** these validation tests and not the other generic schema tests already included in the base package.
+```zsh
+dbt test --select tag:validations --vars '{fivetran_validation_tests_enabled: true}'
+```
