v0.9.0

Highlights

Added protostar multicall command

Multicall executes multiple calls as a single transaction. If one call fails, the entire operation is aborted. Use it to prevent leaving your system in an inconsistent state.

Changed protostar deploy to use Universal Deployer Contract

protostar deploy invokes a Universal Deployer Contract, which deploys the contract with the given class hash and constructor arguments.

Removed deprecated protostar migrate

The migrations functionality has been removed in favor of using JSON outputs of the commands, and creating the deployment scripts in a language of your choice.
