Features
Add EIP 2930 support to EthTXData (#7696)
Previously only legacy and type 2 Ethereum transactions were supported. The EIP-2930 transactions can be sent either directly to HAPI via an EthereumTransaction or via the JSON-RPC Relay. The transaction type is used by a few tools such as web3 and etherjs in transaction submission flows and allows supports legacy parameters along with the accessList parameter. Notably, Hedera does not utilize access list logic at this point.
Modify config to support state on disk by default (#8510)
Enables the Data on Disk feature by default. Starting in this release, state will be stored on disk instead of in memory. This is an initial deployment and will enable higher entity maximums in the future.
Disable account balance exports (#8272)
Disables the creation of account balance files. This change is necessary to allow the state to scale to a larger number of entities enabled by the Data on Disk feature without compromising performance. The Hedera mirror node will now produce equivalent account balance snapshots internally.
