Latest Protocol Releases

Calling all Validators!

We're rolling out a new upgrade for your nodes! This release introduces:

• An important fix for nodes starting an epoch in a new shard without recent DB info. This is necessary for shuffled-out validator nodes.

This enhancement ensures smooth state synchronization, even when a setGuardian transaction occurs at the epoch change. As always, ensure you're using the right Go compiler version (v1.20.7). Happy upgrading, and don't forget to join our Discord community for discussions, support, and sharing innovative ideas.

Hello xWorld!

• Fixed a rustc compatibility issue when building contracts. The meta crate looks at the rustc version when generating the wasm crate code.
• Initial version of the contract template tool in multiversx-sc-meta.
• The Rust debugger is now thread safe.
• Removed the `big-float` feature of multiversx-sc, because the functionality is already available on mainnet.
• CLI fixes in multiversx-sc-meta: arguments `--target-dir-wasm`, `--target-dir-meta`, and `--target-dir-all` in the `multiversx-sc-meta`
• Fixed an issue with contract calls and ESDT transfers in the `StaticApi` environment.
