v0.9.1

StarkNet:

• API changes:
  • Add get_block_traces API - returns all the transaction traces of a given block
  • Add a list of declared contracts in get_state_update
  • Add a 0x prefix for class hash in the API
  • Add starknet_version field for blocks (only applies to new blocks)
• StarkNet CLI:
  • Change the default block number to pending
  • Using a wallet is the default, --no_wallet must be specified explicitly to override this
  • Deploying contracts:
    • Add deploy_contract function to the account contract created by starknet deploy_account
    • Use this function to deploy contract (unless using --no_wallet). In particular, deploy should be used after declaring the contract (it expects the contract class hash)
  • Support --dry_run to get the transaction information without signing or sending it
• Support deploy_from_zero in the deploy syscall to deploy a contract to an address that does not depend on the deployer

Cairo:

• Support and in if statements (if x == y and z == w). Note that at the moment other boolean combinations are not supported
