Latest API Releases

Hello xBuilders!
This is the major rebranding release for the smart contract framework and all adjacent tools. It is not merely a rebranding; it also comes with a major reorganization of the crates and some new functionality.
These release notes also cover hotfix updates 0.39.1 to 0.39.5, which mostly added more smart contract tooling and fixes to those tools.

• All crates renamed and reorganized;
• The meta crate;
• The scenario testing facade;
• The Rust SDK crate;
• Twiggy post-processing;
• ManagedVec supports sorting and de-duplication;
• migrateUserName builtin function mock;

Hello xWorld!
You better not cry
You better not pout
I'm telling you why

elrond-wasm 0.38.0 is coming to town. And it brings:

• ContractCall refactor. Building a contract call comes with harder compile-time constraints. This also reduces compiled code size.
• ContractBase supertrait can be now stated explicitly for contract and module traits.
• As per debugger: callback payment is now set correctly and function names are represented internally as strings instead of bytes, which aids debugging.
• Removed the ei-1-2 feature, which was guarding the newer VM functions. These functions are in the mainnet, so this feature is no longer needed.
• New utility functions: self.send().esdt_local_burn_multi(...), self.blockchain().get_token_attributes(...).
• Updated all crates to Rust 2021.

Hello xWorld! Lots of efforts are invested in the migration to xExchange and MEX2.0, but results of accumulated hard work over months, on a separate pillar of MultiversX ecosystem, begin to bloom. We are releasing new features as:

• New multi-contract build system for contracts - starting now, you can configure a so-called “multi contract build”;
• Support for promises;

and improvements as:

• Refactor on elrond-codec;
• Improvements on the System SC Proxy - (kudos for community);
• Updates on several modules;
• Improvements on storage mapper;

Good news everyone!

If you encountered issues while decoding EsdtTokenPayment, you may want to read this:

• EsdtTokenPayment legacy decode: objects encoded by older versions of the framework can now also be decoded, if flag esdt-token-payment-legacy-decode is active;
• Codec NestedDecodeInput new peek_into method;
• FungibleTokenMapper caches the token identifier.

Nothing groundbreaking, just a sum of smaller features that had accumulated:

• Rust interactor snippet generator.
• Added some missing substitution rules in the contract preprocessor.
• Allow single zero byte when top-decoding Option::None.
• Ongoing operations module.
• Claim developer rewards module.
• FromIterator trait for ManagedVec .
• Mandos \"id\" accepted as synonym to \"txId\".
