+### 1.3.0
+
+- Support the `Expression#around` hook, which executes code around both `interpret` and `add_content`
+
 ## 1.2.0
 
 - Alter `Engine`/`Expression`/`ParentExpression` API to pass `keyword` and `args` to `#add_content` method. This enables consumers to vary behavior based on `keyword` and `args`, not just `parent` and presence of `block`.
 
 ## 1.1.2
