High-level summary​

Ledger 8.0.3 is a patch release that fixes transcript partitioning and transaction construction for flows that combine unshielded and/or shielded transfers with contract calls. It corrects transfer fee accounting, tightens fee approximation during transaction construction, and fixes a Zswap proof issue in specific construction paths.

This release does not affect node or indexer-side processing. It is limited to transaction construction logic.

Audience​

This release note is relevant for developers who construct transactions using the ledger APIs through JS or Rust bindings.
