**Starknet**
* Use [EIP 4844](https://eips.ethereum.org/EIPS/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`
