Transaction Changes

FeeParameters::native_asset_id was renamed to fee_faucet_id and FeeParameters::new is now infallible. The transaction-script root is now a typed TransactionScriptRoot rather than a raw Word. These changes affect anyone constructing fee parameters, reading transaction-script roots, or building batches by hand.

fee_faucet_id replaces native_asset_id on FeeParameters​

Summary​

FeeParameters::native_asset_id (field, getter, and new parameter) was renamed to fee_faucet_id. Because account IDs no longer encode faucet‑ness, FeeParameters::new no longer validates that the ID is a fungible faucet and is now infallible (returns Self, not Result).

Migration Steps​

  1. Rename native_asset_id → fee_faucet_id at the constructor, field, and getter.
  2. Drop the ? / FeeError handling on FeeParameters::new.

TransactionScript::root() returns TransactionScriptRoot​

Summary​

(v0.15.2) TransactionScript::root() now returns a typed TransactionScriptRoot newtype instead of a raw Word (convert with .into()). A new TransactionScript::from_package(&Package) builds a script from a compiled miden-mast-package package, and the new tx::get_tx_script_root kernel proc returns the executed tx‑script root (empty word if none).

Migration Steps​

  1. Update the binding type of tx_script.root() to TransactionScriptRoot.
  2. Insert .into() / Word::from(root) where a Word is required.

ProvenBatch::new → new_unchecked; NoteConsumptionInfo fields private​

Summary​

Batch/transaction housekeeping changes that affect anyone constructing these types by hand:

  • ProvenBatch::new was renamed ProvenBatch::new_unchecked to signal it skips validation.
  • NoteConsumptionInfo (and related types) gained cycle counts and had their fields made private; use the accessor methods successful() / failed().

Migration Steps​

  1. Rename ProvenBatch::new → ProvenBatch::new_unchecked.
  2. Replace direct field access on NoteConsumptionInfo with the accessor methods.
