1. More reliable classification of transactions in the txpool (into pending, basefee, and queued sub pools). Improved performance of pool reprocessing on basefee changes (~10 ms for a pool with 250k transactions).
2. Further fixes to transaction parsing and encoding - this has been an issue for a few past releases.
3. txpool_content RPC method now separates pending and basefee sub pools (previously, they were lumped into pending pool). Performance of txpool_content has been significantly improved.
4. Transactions with gas parameter larger than current block gas limit do get promoted to pending anymore and are not served to the miner / block proposer.
5. Better txpool documentation, option --txpool.trace.senders is now available when txpool(s) run in a separare process (yes, it is possible!)
6. MDBX assertion fix that allows databases grow over 4Tb without crashing.
7. MDBX produces more helpful error messages when DB corruption happens (with some recommendations about what to do).
8. Added experimental WatchTheBurn stage (disabled by default needs to be turned on with --watch-the-burn command line option). This allows tracking issuance (and burning or ETH) via erigon_issuance RPC method.
9. p2p sentry propages “peer disconnected” event to Erigon.
10. Updates to pre-verified hashes for Ropsten and Mainnet, change of skip analysis optimisation parameter
