Neo has released the Neo X Gamma version of its testnet. This version introduces a strategy-based transaction fee burning mechanism, replacing EIP-1559's dynamic evaluation base fee. This version also includes compatible protocol extensions, enhanced system contract functions, improved cross-chain bridge, and document updates. In addition, after security audit, this version has made enhancements and stability fixes to system contracts and dBFT protocols. The Neo X node of this version is based on v1.13.11 Geth and supports the Shanghai fork as the latest Ethereum-compatible fork. Neo X plans to use the Gamma version as a long-term TestNet.
