[TRON Releases java-tron v4.8.1 Pre-Release Version and Initiates Mandatory Upgrade on Nile Testnet] On November 28, TRON officially announced that the java-tron v4.8.1 pre-release version has been officially launched on the Nile Testnet as a mandatory upgrade version, requiring all Nile nodes to complete the update as soon as possible. This upgrade covers modules such as consensus core, virtual machine, network, event service, and API, aiming to enhance the performance, security, and cross-architecture compatibility of the TRON network. According to the Nile Testnet official website, this upgrade introduces support for the ARM architecture, incorporates TIP-6780 to adjust the SELFDESTRUCT instruction, optimizes P2P communication and event queries, expands block receipt and SR vote query interfaces, and upgrades the toolchain to improve system performance and maintainability. Additionally, the GreatVoyage-v4.8.1 version introduces proposals that require on-chain governance voting to determine whether they take effect on the testnet. Whether these upgrades will be applied to the mainnet will depend on the progress of the upgrade and the governance results.
