sc 0.64.0, codec 0.24.0, chain 0.21.0, sdk 0.14.0, scenario-format 0.25.0

• Switched to Rust edition 2024, minimum compiler version becomes 1.85.
• New payments API:
  • New objects: TokenId and Payment. Besides them having shorter names, they treat EGLD the same as all other ESDTs, making their handling easier. EGLD is always serialized as EGLD-000000.
  • Payment amounts are NonZeroBigUint, a new refinement type that prevents the value from being zero. This prevents at compile time zero-value payments from occurring.
  • New call_value methods:
    • all() - all payments, EGLD and ESDT;
    • single() - expect precisely one payment, and retrieve that payment. Crash for no payments, or for multiple payments;
    • single_optional() - expect either zero or one payments. Returns an Option of Payment reference;
    • array() - expect the exact number of payments and retrieve them as array.
  • MultiTransfer marker for forcing an ESDT multi transfer, even when not strictly necessary.
  • Deprecated EgldOrMultiEsdtPayment and call_value``any_payment.
  • ManagedVecRef renamed to Ref.
  • Token identifier display fix.
• NonZeroBigUint implementation, including all common operators. Additional fixes for the BigInt and BigUint operators.
• SDK - fixed an issue with parsing transactions with large values in SCRs.
• Upgraded all dependencies.

sc 0.63.3

• Reverted the EsdtTokenIdentifier ABI name to TokenIdentifier.

sc 0.63.2

• Legacy whitebox test block timestamp APIs renamed and made type-safe.

sc 0.63.1

• Blockchain API renames: epoch_start_block_* -> get_epoch_start_block_*, for consistency.
• Set block timestamp methods renamed to block_timestamp_seconds and block_timestamp_millis, respectively, also for consistency.

sc 0.63.0, chain 0.20.0, sdk 0.13.0, scenario-format 0.24.0

• New block info API, which returns timestamps as either TimestampSeconds or TimestampMillis, instead of just u64:
  • New types for measuring time, not only timestamps, but also durations (DurationSeconds and DurationMillis);
  • Previous functions deprecated in favor of the new ones as follows:
    • get_block_timestamp -> get_block_timestamp_seconds
    • get_block_timestamp_ms -> get_block_timestamp_millis
    • same for previous block and epoch start block
    • get_block_round_time_ms -> get_block_round_time_millis;
  • Support for TimestampSeconds and TimestampMillis when setting up blackbox tests;
  • Mandos support for millisecond timestamps, in both mandos-go and mandos-rs.
• Rust VM support for fallible sync calls. Adjusted event logs to match the Go VM.
• Contract build improvements:
  • The Rust version is now sent to the wasm build command via CLI, always. This overrides all other settings, giving the framework full control over the Rust version used.
  • The Rust version can be configured in sc-config.toml. This overrides all other settings. If missing, the current config will be detected and used explicitly.
  • The wasm-opt version can be specified in sc-config.toml. While sc-meta cannot install or change this version, it will crash if there is a version mismatch, signalling problems with reproducible builds.
  • The sc-meta standalone tool signals version incompatibilities when building contracts. Most importantly it writes a warning to console if multiversx-sc version < v0.58 and rustc ≥ v1.87.
  • Added a deprecated VM hooks checker mechanism. Currently only checks for legacy call value getters.
  • ABI build info improvements:
    • Added host;
    • Added LLVM version;
    • Rustc version guaranteed to match the one used for building the wasm binary;
    • Ensured historical backwards compatibility, back to the first version of the ABI format.
• TokenIdentifier renamed to EsdtTokenIdentifier, since the old name was misleading. Old name kept as alias, for backwards compatibility.
• Fixed proxy imports in snippets.

sc 0.62.0, chain 0.19.0, sdk 0.12.0

• BLS signing support in tests.
• Gas simulations available in the interactor:
  • Simulation only;
  • Auto-simulate to find gas estimation.
• sc-meta post-build validation improvements:
  • Fixed opcode checker to support call_indirect.
  • Opcode versioning in sc-config.toml and opcodde checker.
  • Post-build VM hook signature validation.
• Proxy generator fix for enums with explicit discriminants.
• Removed legacy typed mandos scenario and interactor syntax.

sc 0.61.0, chain 0.18.0, sdk 0.11.3

• BLS crypto function support in the Rust VM. Functionality is guarded by the bls feature flag.
• Managed buffer slices out of bounds handled in the framework.
• Interactor - fixed log management.

sc 0.60.0, chain 0.17.0, sdk 0.11.2

• Block info hooks:
  • Rust VM support for the new block/round info hooks: getBlockTimestampMs, getPrevBlockTimestampMs, getBlockRoundTimeMs, epochStartBlockTimestampMs, epochStartBlockNonce, epochStartBlockRound;
  • Blackbox test syntax for setting all block info.
• Cleanup after Barnard:
  • Removed the barnard feature. All functionality is routed to the new Barnard hooks, where appropriate.
  • Reverted routing non-fallible transfer execute through the fallible vm hook. This preserves pre-Barnard behavior for most cases.
• sc-meta install mx-scenario-go retries several times in case of connection issues.

sc 0.59.1, codec 0.23.1, chain 0.16.1, sdk 0.11.1

• Governance proxy improvements.
• Codec: added support for using u128.
• SDK/interactors:
  • Added logging for http requests and responses;
  • Fixed an issue with retrieving results from transactions with multi-transfer ESDT.
  • Fixed a VM query error handling issue.

sc 0.59.0, codec 0.23.0, chain 0.16.0, sdk 0.11.0

• Support for Barnard features
  • barnard feature for smart contracts, can be enabled in the contract's Cargo.toml or sc-config.toml;
  • Blockchain API new features:
    • Code hash API;
    • Block info:
      • Timstamps in milliseconds: get_block_timestamp_ms, get_prev_block_timestamp_ms, epoch_start_block_timestamp_ms;
      • Block round time: get_block_round_time_ms;
      • Epoch start info: epoch_start_block_timestamp_ms, epoch_start_block_nonce, epoch_start_block_round.
    • ESDT info:
      • Token type API supplied by the protocol (get_esdt_token_type);
      • get_esdt_token_data provides the token type supplied by the protocol;
      • EsdtTokenType updated with new ESDT types (meta & dynamic tokens).
  • New transaction mechanisms:
    • Fallible synchronous call;
    • Fallible transfer-execute;
    • Both are integrated in the unified syntax;
    • Simplified several scenarios by routing all through the fallible tx VM hooks.
  • Optimisations:
    • Multi-transfer call value including the direct EGLD is now provided by the VM directly.
    • Direct conversion between ManagedBuffer and i64 (small integer) now provided directly by the VM.
• Back transfers now support multi-transfers with EGLD properly
  • New BackTransfer structure contains back-transfers as a multi-transfer list;
  • It contains methods to filter and extract EGLD or single ESDT values;
  • New implementation of ReturnsBackTransfers and ReturnsBackTransfersReset, which work with this payment list;
  • ReturnsBackTransfersEGLD now supports multi-transfer;
  • Old implementations renamed to *Legacy.
• New proxies for system smart contracts:
  • Governance system SC;
  • Delegation system SC.
• Core crate updates:
  • Bech32Address:
    • Deduplicated and moved to the core crate, guarded by a std feature;
    • Support for custom HRP;
  • BLSKey and BLSSignature types, to help the interaction with the delegation contract.
• sc-meta:
  • Support for building contracts with std library;
  • test-gen support for #[should_panic] annotation.
• Validator processing in the SDK, including parsing from pem.
• Event log name can now be empty or missing in declaration, the method name will be used in this case.
• Fixed a bug in mandos-rs, it was not handling a failing scQuery properly.
• Codec: improved multi-value length handling.
