Latest Protocol Releases

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:

Good news everyone!

A new release for Mainnet is available. This release will fix some bothersome issues discovered after v1.3.42 upgrade. That’s why:

• intercepted trie nodes are no longer saved as unmarshalled entities in cacher;
• we have a new trie syncer (v3);
• we removed unnecessary gasComputation.Reset call;
• we fixed the old NFT liquidity handling issue… (yes, you can transfer your old NFTs again);
• we fixed also the preferred peers loading.
