Changelog.md

@@ -33,7 +33,9 @@ AST Changes:
 
 Language Features:
  * Code generator: Support copying dynamically encoded structs from calldata to memory.
+ * Code generator: Support copying of nested arrays from calldata to memory.
  * The fallback function can now also have a single ``calldata`` argument (equaling ``msg.data``) and return ``bytes memory`` (which will not be ABI-encoded but returned as-is).
+ * Wasm backend: Add ``i32.select`` and ``i64.select`` instructions.
 
 Compiler Features:
  * Code Generator: Avoid memory allocation for default value if it is not used.

 Of course, you can also directly access the members of the struct without
 assigning it to a local variable, as in
 ``campaigns[campaignID].amount = 0``.
+
+.. note::
+    Until Solidity 0.7.0, memory-structs containing members of storage-only types (e.g. mappings)
+    were allowed and assignments like ``campaigns[campaignID] = Campaign(beneficiary, goal, 0, 0)``
+    in the example above would work and just silently skip those members.
