elrond-wasm 0.32.0, mandos 0.14.0

• VM new functionality added as part of the environment interface 1.2:
  • Fully managed functionality for elliptic curves (no allocator);
  • Fully managed cryptographic functions (no allocator);
  • More efficient printing of big ints and hex;
  • Functionality available by adding the ei-1-2 flag to contracts.
• BigFloat functionality. Since the functionality is not yet deployed on mainnet, use flag big-float to use.
• Major refactoring of the call value mechanism:
  • TokenIdentifier now only refers to ESDT, for mixed EGLD+ESDT we have EgldOrEsdtTokenIdentifier.
  • EsdtTokenPayment now only refers to ESDT, for mixed EGLD+ESDT we have EgldOrEsdtTokenPayment.
  • Compact version for multi-transfer: let [payment_a, payment_b, payment_c] = self.call_value().multi_esdt();.
  • Explicit single_esdt vs. single_fungible_esdt vs. egld_or_single_esdt vs. egld_or_single_fungible_esdt.
  • Payment arguments are still supported, although discouraged. They always assume the EGLD+ESDT scenario.
• ManagedOption provides some minor optimization for specific use-cases. Mostly for use in the framework.
• Cleanup in the callback mechanism and in the SendApi.
• SparseArray implementation.
• UniqueIdMapper - efficient storage mapper for holding unique values.
• The ABI also contains events.
• New standard module: StakingModule.

elrond-wasm 0.31.1, mandos 0.13.1

• Bugfix - formatter single char issue.

elrond-wasm 0.31.0, elrond-codec 0.11.0, mandos 0.13.0

• Improved formatter. Strings can be formatted similarly to the standard Rust ones, but without allocator, using managed buffers. Macros require!, sc_panic!, sc_format!, sc_print! use it.
• Removed build flag ei-1-1, following mainnet updated and new VM endpoints being available. Among others, managed sha256 and keccak256 APIs can be used freely.
• CodecFrom and CodecInto traits to define equivalent encodings and conversions via codec.
• Generated smart contract proxies use the CodecFrom/CodecInto traits to accept a wider range of types.
• Mandos Rust testing framework v2, which uses contract proxies for composing calls and is capable of building and exporting mandos scenarios.
• Managed type handle management system in the contract, to reduce the number of API calls to the VM. General VM API refactor.
• Eliminated #[var_args] annotation. The framework can now distinguish between single-values and multi-values solely based on type.
• Contract cleans up return data after performing synchronous calls. Getting return data by range is no longer needed and the respective methods have been removed.
• Fixed behavior of blockchain API get_esdt_token_data.
• Git tag/commit info in ABI (fixed & reintroduced).

elrond-wasm 0.30.0, elrond-codec 0.10.0

• Feature flags in elrond-wasm:
  • alloc allows contracts to use the heap allocator. It is not a hard restriction, there is still access to the implementations of the heap-allocated types, but they are not imported. Some methods are only available with this flag.
  • ei-1-1 allows contracts to use VM endpoints that are not yet available on the mainnet.
• Fixes with async calls, smart contract deploy & upgrade.
• Refactoring regarding small number types in the API.
• Rust testing framework: Allow checking NFT balance without also checking attributes.
• View for MapMapper.

elrond-wasm 0.29.3

• ManagedVec backwards compatible implementation for set.
• Implemented ManagedVecItem for Option<T>.

elrond-wasm 0.29.2

• Disabled git tag/commit info in ABI due to issue in standard modules.

elrond-wasm 0.29.0

• Cleaned up allocator from modules: DnsModule, EsdtModule, FeaturesModule, PauseModule, UsersModule.
• Crypto API managed wrapper over legacy VM endpoints.
• Managed multi-value types refactor and rename.
• ManagedVec - remove, contains, find.
• ManagedVecItem derive for simple enums.
• Feature cb_closure_managed_deser replaced by cb_closure_unmanaged_deser, managed implementation is now the default.
• Git tag/commit info in ABI.

elrond-wasm 0.28.0, elrond-codec 0.9.0, mandos 0.12.0

• Major elrond-codec refactor:
  • Redesigned the error handling for single value encoding
  • Introduced multi-value encoding, which replaces the previous endpoint argument and result mechanisms
• Mandos improvements:
  • Multi-values: out, topics, ESDT uri
  • Logs "+" wildcard
• Builtin function mocks: ESDTNFTUpdateAttributes, ESDTNFTAddURI
• New storage mappers: FungibleTokenMapper, NonFungibleTokenMapper, WhitelistMapper
• Call value wrapper avoids using invalid token index in requests

elrond-wasm 0.27.4, elrond-codec 0.8.5

• Backwards compatibility fix.

elrond-wasm 0.27.3

• Backwards compatibility fix.
• Trailing commas are allowed in sc_panic!, require! and sc_print!.
• EsdtTokenData decode_attributes_or_exit for easier error handling.
