 ## Changes
 
+### 1.0.1
+
+- Fixed the Incremental method implementation (was buggy/incomplete)
+   - Removed the `unique_id` as it wasn't implemented
+   - Fixed when no fields were added - full table merge
+- Added testing for Incremental materialization
+  - Testing for dbt Incremental full table
+  - Testing for dbt Incremental specified merged columns
+- Added more logging to the connector to help understand why tests were failing
+- Using the official [Vertica CE 11.0.x docker image](https://hub.docker.com/r/vertica/vertica-ce) now for tests
+
 ### 1.0.0
 
-- Add support for DBT version 1.
