+title: Transact without having to specify weight
+
+doc:
+  - audience: [Runtime User, Runtime Dev]
+    description: |
+      In XCMv5, it's no longer required to pass in the expected weight when using
+      `Transact`.
+      This was made to remove a whole class of bugs where the weight specified
+      was not enough.
