Neo plans to upgrade the Neo-CLI to version 3.6.2 on December 4th
ChainCatcher message, Neo announced that it will release Neo-CLI v3.6.2 on November 17, deploy it to the T5 testnet on November 21, and deploy it to the mainnet on December 4.
It is reported that this version includes improvements and optimizations such as: adding a new system call "CurrentSigners" to obtain the current transaction signers; adding a new function "StrLen" in the native StdLib contract name to get the string length in the smart contract; setting attribute fees for transactions with the "conflict" property, and adding a cancel command in neo-cli and rpc to cancel transactions that have not yet been on-chain.
This upgrade involves changes to native contracts and the virtual machine. It is crucial to resynchronize data during the upgrade. Do not use the old version of the configuration file config.json.
