 ## [9164206ef1fcf3e577820442b5afbad92d03ffa4] - 2020-02-09
 ### Changed
 - Mutation of variables inside lambdas passed to list_iter do not have effect anymore. Side-effects used to survive iterations of list_iter via a quirk in the Michelson list_iter. Now, either use a list_fold and explicitly pass through the updated variables (e.g. storage) to the next iteration, or use a `for` loop which automatically detects mutations within the loop body and lifts the affected variables to a record that is passed from iteration to iteration.

+## Origination of a contract
+
+`Tezos.create_contract` allows you to originate a contract given its code, delegate (if any), initial balance and initial storage.
+The return value is a pair of type `(operation * address)`.
+
+> ⚠️ Due to limitations in Michelson, `Tezos.create_contract` first argument
+> must be inlined and must not contain references to free variables
