 ## Swift 5.7
 
+* [SE-0347][]:
+
+  It's now possible to use a default value expression with a generic parameter type
+  to default the argument and its type:
+
+  ```
+  func compute<C: Collection>(_ values: C = [0, 1, 2]) {
+    ...
+  }
+  ```
+
+  `compute` is now accepted by compiler and `[Int]` is going to be inferred
+  for `C` at call sites that do not provide the argument explicitly.
+
 * [SE-0326][]:
 
   It's now possible to infer parameter and result types from the body of a multi-statement
