ethereum.forks.cancun
The Cancun fork (EIP-7569) introduces transient storage, exposes beacon chain roots, introduces a new blob-carrying transaction type, adds a memory copying instruction, limits self-destruct to only work for contracts created in the same transaction, and adds an instruction to read the blob base fee.

ethereum.forks.prague
The Prague fork enables deploying code into externally owned accounts (EOAs)
via the SetCodeTransaction, increases the blob throughput, increases the
cost of calldata-heavy transactions, introduces general execution layer
requests (and two request types: consolidation, and withdrawal),
appends validator deposits to execution layer blocks, creates BLS12-381
precompiles, and exposes historical block hashes through a system
contract.
