• Reindexing Mode: This release introduces the Reindexing mode for the Neon Indexer. This mode streamlines the restart process of the Neon Indexer during upgrades. In Reindexing mode, the Neon Indexer initiates the indexing of new Neon EVM transactions from the Solana cluster's latest finalized slot. Simultaneously, it collects blocks with transactions executed by other operators between restarts. Consequently, the Neon Proxy can promptly process user transactions without requiring synchronization with the Solana cluster, thanks to background syncing.
• HTTP/2 Protocol: The HTTP interaction between Neon Proxy/Indexer and Solana has transitioned to the HTTP/2 protocol. This protocol offers numerous advantages, notably significantly increased data transfer speed between server and client. The most notable performance improvement is observed in the indexing of blocks by the Neon Indexer, where indexing speed is enhanced by a factor of three.
• Optimized Transaction Processing: This release improves the speed of processing Neon transactions with high nonces while waiting for the transaction counter in the Solana state. This situation typically arises when users dispatch transactions with differing nonces to the mempools of various operators.
