v0.13.1

Starknet

• Use EIP 4844 for cheaper data availability

• Time-related syscalls when called from account contract's __validate__:

  • timestamp will return the hour, rounded down
  • block_number will return the block number rounded down to the nearest multiple of 100

• Optimization: Load only the used functions in a contract into memory when generating the proof

• Add starknet-compiled-class-hash command

• API changes:

  • Starknet block:
    • New field l1_da_mode, which indicates whether EIP 4844 was used in the block
    • eth_l1_gas_price and strk_l1_gas_price were replaced, and the information now contains the data gas price (EIP 4844) in addition to the regular gas price
    • execution_resources in transaction receipt now contains:
      • data availability resources
      • syscall resources (which contribute to the transaction fee but were not included in the receipt until this version)
    • transaction_commitment and event_commitment are added to the block (zero is returned for old blocks)

• Infrastructure updates:

  • Support multiple L1 providers

• CairoZero:

  • Remove 128-bit limitation from search_sorted_lower
