v0.11.0

In this version we added debugging capabilities to the new Transaction Builder

This release also contains several breaking changes, please refer to the migration notes for more information.

cashc compiler

• 🐛 Fix bug where source code in --format ts artifacts used incorrect quotation marks.
• 🛠️ Remove warning for opcount and update warning for byte size to match new limits.
• 💥 BREAKING: tx.age was renamed to this.age to better reflect that it enforces a UTXO-level locktime check (not transaction-level).
• 💥 BREAKING: The entire debug object on the artifact is reworked to enable debugging the optimised contract bytecode.

CashScript SDK

• ✨ Add debugging capabilities to the TransactionBuilder.
  • transaction.debug() & transaction.bitauthUri()
  • Output BitAuth IDE URI for debugging when transaction is rejected.
  • Libauth template generation and debugging for multi-contract transactions
• ✨ Debugging now supports using the optimised contract bytecode (when compiled with cashc@0.11.0 or later).
• ✨ Add setBlockHeight() method to MockNetworkProvider
• ✨ Config-free usage of the CashScript SDK with Vite or Webpack
• 🛠️ Update debug tooling to use the new BCH_2025_05 instruction set.
• 🛠️ Deprecate the simple transaction builder. You can still use the simple transaction builder with the current SDK, but this support will be removed in a future release
• 💥 BREAKING: the Jest utilities for automated testing are now synchronous and no longer work with the deprecated simple transaction builder
  • expect(transaction).toLog(message)
  • expect(transaction).toFailRequire()
  • expect(transaction).toFailRequireWith(message)
• 💥 BREAKING: Remove support for custom Clusters from ElectrumNetworkProvider and added a configuration object to the constructor.
• 💥 BREAKING: Remove support for old contracts compiled with CashScript v0.6.x or earlier.
• 🐛 Fix bug where JestExtensions expect().toLog() would detect logs from different tests.
• 🐛 Fix bug where certain edge cases in require statements caused the FailedRequireError message to be slightly different from the original error message.

@cashscript/utils

• 💥 BREAKING: Remove importArtifact and exportArtifact helper functions. If you want to import or export artifacts, use 'fs' to read and write files directly.
