Neo-CLI v3.6.2 was released on November 17th, 2023, and will be deployed to T5 TestNet on November 21st,2023, and to MainNet on December 4th, 2023. Below is a list of improvements and optimizations included in this release:

• Add a new syscall “CurrentSigners” for getting current tx signers

• Add a new function in native StdLib contract name as “StrLen” for getting String length in smart contract.

• Set attribute fee for transactions with “conflict” attribute

• Add cancel command both in neo-cli and rpc for canceling transactions which haven’t been on-chain yet.

Please note: This upgrade involves changes to native contracts and the VM. When upgrading, it's essential to resynchronize data. Do not use the old version of the configuration file, config.json.
