+[PR #119](https://github.com/fivetran/dbt_fivetran_log/pull/119) includes the following updates:
+
+## 🚨 Breaking Changes 🚨: Bug Fixes
+- The following fields have been deprecated (removed) as these fields proved to be problematic across warehouses due to the end size of the fields.
+  - `errors_since_last_completed_sync`
+  - `warnings_since_last_completed_sync`
+> Note: If you found these fields to be relevant, you may still reference the error/warning messages from within the underlying `log` table.
+- The `fivetran_platform_using_sync_alert_messages` variable has been removed as it is no longer necessary due to the above changes.
+
+## Feature Updates
+- The following fields have been added to display the number of error/warning messages sync last completed sync. These fields are intended to substitute the information from deprecated fields listed above.
+  - `number_errors_since_last_completed_sync`
+  - `number_warnings_since_last_completed_sync`

 # dbt_fivetran_log v1.6.0
 [PR #117](https://github.com/fivetran/dbt_fivetran_log/pull/117) includes the following updates as a result of users encountering numeric counts exceeding the limit of a standard integer. Therefore, these fields were required to be cast as `bigint` in order to avoid "integer out of range" errors:

 By default, this package will run using your target database and the `fivetran_log` schema. If this is not where your Fivetran Platform data is (perhaps your fivetran platform schema is `fivetran_platform`), add the following configuration to your root `dbt_project.yml` file:

 ## (Optional) Step 5: Additional Configurations
 
-### Configuring Fivetran Error and Warning Messages
-Some users may wish to exclude Fivetran error and warnings messages from the final `fivetran_platform__connector_status` model due to the length of the message. To disable the `errors_since_last_completed_sync` and `warnings_since_last_completed_sync` fields from the final model you may add the following variable to you to your root `dbt_project.yml` file. By default, this variable is assumed to be `true`:
-
-```yml
-vars:
-    fivetran_platform_using_sync_alert_messages: false # this will disable only the sync alert messages within the connector status model
-```
-
 ### Change the Build Schema
 By default this package will build the Fivetran staging models within a schema titled (<target_schema> + `_stg_fivetran_platform`)  and the Fivetran Platform final models within your <target_schema> + `_fivetran_platform` in your target database. If this is not where you would like you Fivetran staging and final models to be written to, add the following configuration to your root `dbt_project.yml` file:
