-- **BREAKING** `hydra-node` `/commit` enpoint now also accepts a _blueprint/draft_
-  transaction together with the `UTxO` which is spent in this transaction. `hydra-node` can
-  still be used like before if the provided `UTxO` is at public key address. In order to spend
-  from a script `UTxO`, and also unlock more involved use-cases, users need to provide additional
-  unsigned transaction that correctly specifies required data (like redeemers, validity ranges etc.)

+- **BREAKING** Change `hydra-node` API `/commit` endpoint for committing from scripts:o
+  - Instead of the custom `witness` extension of `UTxO`, the endpoint now accepts a _blueprint_ transaction together with the `UTxO` which is spent in this transaction.
+  - Usage is still the same for commiting "normal" `UTxO` owned by public key addresses.
+  - Spending from a script `UTxO` now needs the `blueprintTx` request type, which also unlocks more involved use-cases, where the commit transaction should also satisfy script spending constraints (like additional signers, validity ranges etc.)
