+# v0.278.1 Breaking Changes
+
+This release removes `strawberry.http.exceptions`. HTTP-related exceptions can
+now be imported directly from the `lia` package.
+
+For example, instead of:
+
+```python
+from strawberry.http.exceptions import HTTPException
+```
+
+Now you need to do:
+
+```python
+from lia import HTTPException
+```
