0.63.0

Forge

Added

• declare! macro for declaring contracts using Cairo paths. Read more here.
• Debugging traces now display the class hash for forked contracts.
• declare_from_file function for declaring contracts from Sierra contract class JSON files. Read more here.

Changed

• Actual and Expected panic data in the #[should_panic] mismatch message now labels rendered values inline, making it clear whether each value is a ByteArray or a felt252.
• Minimal recommended Scarb version is now 2.18.0 (updated from 2.17.0)
• Re-enabled the add-types-debug-info = true requirement for --launch-debugger on Scarb >= 2.20.0

Fixed

• Malformed byte array panic data (e.g. an untrusted words length) no longer causes a crash when matching #[should_panic] expected data. Additionally, invalid byte array serializations (e.g. bad pending_word_len) are now rejected instead of rendered as a corrupted string.

Cast

Added

• --contract-address flag to get balance command, allowing to check balance for any contract, not only accounts
• get state-update command that fetches the state update for a given block
• Optional --private-key and --private-key-file in account create command to allow specifying a private key for the newly created account

Changed

• sncast show-config now displays network URL overrides specified under [sncast.<profile>.networks].

Fixed

• Re-enabled StarkScan as a supported block-explorer option (currently available only for mainnet).
• get balance command for undeployed accounts

Removed

• Cairo deployment scripts (sncast script command and sncast_std library).
• Deprecated top-level sncast tx-status and sncast balance commands. Use sncast get tx-status and sncast get balance instead.
