The Osaka fork (EIP-7607) includes networking changes (peerDAS), increases the gas cost while limiting the input size of the MODEXP precompile, limits the maximum gas per transaction, raises the blob base fee to always be above the execution cost, limits the RLP-encoded size of blocks, introduces a count leading zeros (CLZ) instruction, and adds a new precompile supporting the secp256r1 curve.
