 * Added support for optional `min_value` and `max_value` parameters to all`*_between_*` tests. ([#70](https://github.com/calogica/dbt-expectations/pull/70))
 
+* Added support for `strictly` parameter to `between` tests. If set to `True`, `striclty` changes the operators `>=` and `<=` to`>` and `<`.
+
+    For example, while
+
+    ```yaml
+    dbt_expectations.expect_column_stdev_to_be_between:
+        min_value: 0
+    ```
+
+    evaluates to `>= 0`,
+
+    ```yaml
+    dbt_expectations.expect_column_stdev_to_be_between:
+        min_value: 0
+        strictly: True
+    ```
+
+    evaluates to `> 0`.

 ## Fixes
 
 * Corrected a typo in the README ([#67](https://github.com/calogica/dbt-expectations/pull/67))
