1. Close node database if erigon fails to start up
2. Compatibility fix for parity_listStorageKeys, now the last parameter needs to be specified, however, only value “latest” is currently implemented.
3. Fix the issue when header sync progress was not updated correctly in the database
4. Compatibility fix for eth_getTransactionByHash - it does not fail when transaction is not found in the database and in the tx pool. Returns nil instead.
5. Asynchronous state streaming and newHead notifications. In the past, slow receievers of state stream and notifications could slow down Erigon’s stage loop.
6. Reverted previous change for header downloaded which might have introduced regression (stuck header download)
7. Updates to pre-verified hashes for Ropsten and Mainnet, change of skip analysis optimisation parameter
