According to official sources, $Neo has released the $Neo X $Gamma version of its testnet. This version introduces a strategy-based transaction fee burning mechanism, replacing the dynamic base fee estimation of EIP-1559. The update also includes compatible protocol extensions, enhanced system contract functionality, improvements to cross-chain bridges, and documentation updates. Additionally, after security audits, this version has made enhancements and stability fixes to system contracts and the dBFT protocol. The $Neo X nodes in this version are based on v1.13.11 Geth and support the Shanghai fork as the latest Ethereum-compatible fork. $Neo X plans for the $Gamma version to be a long-term TestNet solution.
