Latest Protocol Releases

Calling All Validators!

We're rolling out a new upgrade for your nodes! This release maintains full backward compatibility with version 1.6.7.0 previously announced and introduces two key fixes:

• Performance Enhancement: We've addressed a potential performance degradation issue that could occur during the transition epoch when upgrading nodes from version 1.5.x to 1.6.x.
• Node Stability Improvement: A fix has been implemented for a previously identified malfunction in the single-key redundancy node, a critical update to reduce the likelihood of increased Validator/Leader Failures.

For support, queries, or further clarifications, reach out to us on Telegram, Discord, or your preferred communication channel.

Greetings, MultiversX Builders! The Sirius Release (rc/v1.6.7) is officially live, marking a significant milestone in our roadmap. This release introduces over 18 new features, several critical breaking changes, and numerous fixes and improvements. It sets the stage for the upcoming Vega Release and paves the way for our goal of reducing finality time to 3 seconds.

🔧 Key Highlights:

• Multikey Support (#4741): Enhances node functionality by allowing them to sign with multiple keys, boosting security and flexibility in operations.
• Consensus Signature Check Optimization (#4467): Major CPU efficiency improvements in block signature verification during consensus, reducing processing time significantly.
• Governance v3 Contract (#4879): Introduction of a new governance contract in Go, running alongside existing system SCs, offering refined proposal and voting mechanisms.
• DNS v2 (#5045): An update to the DNS functionality, allowing multiple and deletable user names, managed through specialized smart contracts.
• Balance Data Tries (#4636): In the data trie, values are now saved at the hash of the key instead of the original key, ensuring a balanced structure by randomizing the keys. A 'Version' field is added for backward compatibility, and a new API endpoint confirms if an account's data trie is fully migrated.
• VM1.5 (#4789): Integration of the new smart contract processor with features like Multi-async, ManagedBigFloats, ManagedMap, BackTransfers, and updated to Wasmer 2.2.
• Transaction Execution Ordering Refactor (#4918): Redesigns the grouping and execution order of transactions for improved efficiency and reliability in cross-shard interactions.
• Dynamic Gas Cost Introduction(#749): This change addresses a previously unnoticed imbalance—the time consumed for accessing the trie wasn't reflected in transaction consumed gas.

We've covered these updates in our recent developer sessions on Discord. To ensure a seamless transition, we encourage all developers to review the changes outlined below and prepare accordingly before January 16th.

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.
