// Record history of protocol version allocations here:
//
// Version 1: Original version.
// Version 2: Framework changes, including advancing epoch_start_time in safemode.
// Version 3: gas model v2, including all sui conservation fixes. Fix for loaded child object
//            changes, enable package upgrades, add limits on `max_size_written_objects`,
//            `max_size_written_objects_system_tx`
// Version 4: New reward slashing rate. Framework changes to skip stake susbidy when the epoch
//            length is short.
// Version 5: Package upgrade compatibility error fix. New gas cost table. New scoring decision
//            mechanism that includes up to f scoring authorities.
// Version 6: Change to how bytes are charged in the gas meter, increase buffer stake to 0.5f
// Version 7: Disallow adding new abilities to types during package upgrades,
//            disable_invariant_violation_check_in_swap_loc,
//            disable init functions becoming entry,
//            hash module bytes individually before computing package digest.
// Version 8: Disallow changing abilities and type constraints for type parameters in structs
//            during upgrades.
// Version 9: Limit the length of Move idenfitiers to 128.
//            Disallow extraneous module bytes,
//            advance_to_highest_supported_protocol_version,
// Version 10:increase bytecode verifier `max_verifier_meter_ticks_per_function` and
//            `max_meter_ticks_per_module` limits each from 6_000_000 to 16_000_000. sui-system
//            framework changes.
// Version 11: Introduce `std::type_name::get_with_original_ids` to the system frameworks. Bound max depth of values within the VM.

//             `0xdee9::clob_v2` and `0xdee9::custodian_v2`.
// Version 14: Introduce a config variable to allow charging of computation to be either
//             bucket base or rounding up. The presence of `gas_rounding_step` (or `None`)
//             decides whether rounding is applied or not.
// Version 15: Add reordering of user transactions by gas price after consensus.
//             Add `sui::table_vec::drop` to the framework via a system package upgrade.

//             to no longer consult the object store when generating unwrapped_then_deleted in the
//             effects; this also allows us to stop including wrapped tombstones in accumulator.

// Version 17: Enable upgraded multisig support.
// Version 18: Introduce execution layer versioning, preserve all existing behaviour in v0.
//             Gas minimum charges moved to be a multiplier over the reference gas price. In this
//             protocol version the multiplier is the same as the lowest bucket of computation
//             such that the minimum transaction cost is the same as the minimum computation
//             bucket.
//             Add a feature flag to indicate the changes semantics of `base_tx_cost_fixed`.
// Version 19: Changes to sui-system package to enable liquid staking.
