Neo Express has been updated with a number of new features and fixes. As of the latest release, v3.6.94, developers will find new commands for contract updating, executing arbitrary scripts, and token standards validation on deploy.

Key to this update are several new commands, including an update command for contracts as a more user-friendly method for making modifications to deployed code. Other additions include an execute command, for running arbitrary scripts, and a vote command to facilitate governance participation without manual NeoToken native contract invocations.

The latest release notably includes a NEP-11/17 validator, which will run at contract deployment if the manifest declares adherence in the SupportedStandards field. Other improvements include support for WIF-encoded private keys and documentation updates.

Developers can get started using Neo Express by following the installation steps in the GitHub repo:
