Release Notes - v0.204.4

v0.204.4

Title: Normalize script-visible transaction data

Version: v0.204.4

This release normalizes datum and redeemer data before scripts receive it, aligning serialiseData output with cardano-ledger canonical encoding. The correction prevents execution failures when scripts encounter definite and indefinite length encoding mismatches while keeping DatumHash keys based on the original bytes.

🐛 Bug Fixes

• Fixed script-visible datum and redeemer encoding: Scripts now receive canonical encoding from common script contexts and script purpose data.

• Refined inline datum rendering: V1 and V2 resolved inputs and Babbage inline datum payloads now expose normalized data.

• Improved Conway script evaluation: Evaluation paths and ScriptContextV3 redeemers now use canonical script-visible encoding.

• Normalized Dijkstra script data handling: V4 inline and guard datums and evaluation paths now normalize data before script execution.

• Preserved datum hash identity: DatumHash keys continue to use the original datum bytes, even when script-visible data is normalized.

• Updated script data dependency: gOuroboros and its example modules now use plutigo v0.6.1 to provide the canonical normalization behavior.

• Expanded normalization coverage: Tests and the Voting CBOR fixture now verify canonical script-visible data handling.
