sc 0.56.1, chain 0.13.1, sdk 0.8.2

• Bugfix: pretty representation for ManagedAddress when debugging.
• Upgrade dependency: ruplacer.

sc 0.56.0, chain 0.13.0, sdk 0.8.1

• Rust VM support for readonly sync calls.
• ManagedMapEncoded, a map type that can use any key or value types that are serializable.
• ManagedDecimal implements ManagedVecItem.
• Bugfixes, improvements:
  • Fixed a bug regarding the ESDT roles VM hook;
  • Pretty representation for ManagedBuffer and other string-like types when debugging;

  • Snippets generator fixes involving the crate path and the upgrade result handler.

sc 0.55.0, codec 0.21.2, chain 0.12.0, sdk 0.8.0

• Integrating Spica changes into the framework:
  • EGLD+ESDT multi-transfers are now possible:
    • changed the handling of call values: EGLD is treated almost the same as an ESDT in all_transfers and multi_egld_or_esdt, old ESDT methods are given some protection against unexpected scenarios
    • changed the tx unified syntax for sending EGLD+ESDT from contracts, interactors and tests;
    • support in the Rust VM.
  • New built-in functions in the ESDTSystemSCProxy: ESDTModifyRoyalties, SDTSetNewURIs, ESDTModifyCreator, ESDTMetaDataRecreate, ESDTMetaDataUpdate.
• Interactor support for "set state" on the chain simulator.
• Fixed ownership for ManagedVec iterators, specifically reference iterators only produce references to the items.
• Syntax cleanup:
  • #[payable] now allowed instead of #[payable("*")];
  • register_promise allows callback, without calling a function on destination.
• Refactoring and optimizations:
  • Simplified the callback selector;
  • Performance improvements in ManagedVec iterators;
  • Removed some unnecessary bound checks in multi_esdt.

sc 0.54.5

• ManagedVec - deprecated sort and guarded it by the alloc feature, since it uses the allocator.
• sc-meta
  • versioning fix;
  • interactor generator fix.
• Interactors - fixed code metadata on deploy.

sc 0.54.4

• sc-meta
  • install debugger CLI that prepares VSCode extension for debugging;
  • fixed a crash involving templates and installers.
• Deprecated #[derive(TypeAbi)] and added an additional warning in the macro.

sc 0.54.3

• #[storage_mapper_from_address] fixes for: FungibleTokenMapper, NonFungibleTokenMapper, TokenAttributesMapper, UniqueIdMapper, UserMapper, AddressToIdMapper.

sc 0.54.2, codec 0.21.1, chain 0.11.1, sdk 0.7.1

• Codec improvements:
  • MultiValueX - TopDecodeMultiLength implementation fix;
  • ManagedVecItem implented for MultiValue2 and MultiValue3.
• sc-meta snippets improvements.

sc 0.54.1

• sc-meta cs - ChainSimulator CLI, which provides handy functionality to:
  • install the chain simulator image in Docker;
  • start/stop the chain simulator;
  • quick testing using the chain-simulator-tests feature flag.
• Adder interactor cleanup, including in template.
• Interactor - use_chain_simulator builder method, for improved backwards compatibility.
• MultiValueEncodedCounted - a lazy multi-value encoding, but with known number of elements.

sc 0.54.0, sdk 0.7.0, chain 0.11.0

• New crate, multiversx-chain-core, to be used in both framework and Rust VM. It contains common types, flags, and constants that refer to the protocol.
• Major SDK/interactor refactor:
  • Added support for Chain Simulator in interactors:
    • Added chain-simulator-specific endpoints: feed account, advance blocks
    • Added a system to set up accounts in the chain simulator from the interactor;
    • Support for advancing blocks in the interactor;
  • Split SDK crate into:
    • multiversx-sdk - only contains the specifications of the gateway API, without a mechanism to call the API;
    • multiversx-sdk-http - functionality to call the gateway via reqwest;
    • multiversx-sdk-dapp - functionality to call the gateway via wasm-bindgen, to be used in WebAssembly front-ends;
  • Major improvements in the retrieving of transactions and other blockchain data fron the API, many bugs fixed;
  • Support for writing integration tests for interactors, using the Chain Simulator;
    • Also added support for test-related chain-simulator-tests feature flag in sc-meta;
  • Interactors on the front-end:
    • Interactor type made generic over the gateway API implementation, so that it can be used in both front-end and back-end, with no change in the code base;
    • Support for custom random number generation for the front-end;
  • Mechanism for fixing file paths in the interactor context;
  • Fixed an issue with the account tool;
  • Adjusted sc-meta snippets for the new syntax and the chain simulator support;
• Unified syntax:
  • ReturnsHandledOrError result handler, which can gracefully deal with failed transactions;
  • ReturnsGasUsed result handler;
  • PassValue result handler for providing a closure-like context for multi-transaction call/deploy;
  • More specific back transfer result handlers: ReturnsBackTransfersEGLD, ReturnsBackTransfersMultiESDT, ReturnsBackTransfersSingleESDT;
  • Fixed an issue with the update functionality not being general enough;
  • Deprecated prepare_async(), developers can now call run() directly, asynchronously;
• sc-meta improvements:
  • New mechanism for detecting and warning about storage writes in readonly endpoints, integrated into the build system;
  • Support for referencing the framework via git commit, branch, or tag, to make it easier to try out unreleased versions;
  • Support for default-features;
  • Better representation in console of the contract/lib folders, as well as better error messages.
  • Refactoring of the dependency handling logic.
• Fixed the debugger, following changes in the Rust debug tooling.
• ManagedVec set always consumes ownership. Preparations for a profound memory management cleanup.
• ABI:
  • title field and annotation;
  • Refactoring.

sc 0.53.2

• StakingModule fix.
