+## Unreleased

+#### Bug fixes
+
+- Import sorting now ignores side effect imports ([#817](https://github.com/biomejs/biome/issues/817)).
+
+  A side effect import consists now in its own group.
+  This ensures that side effect imports are not reordered.
+
+  Here is an example of how imports are now sorted:
+
+  ```diff
+    import "z"
+    - import { D } from "d";
+    import { C } from "c";
+    + import { D } from "d";
+    import "y"
+    import "x"
+    - import { B } from "b";
+    import { A } from "a";
+    + import { B } from "b";
+    import "w"
+  ```
