 ## New features
 - New ChainIndexer subsystem to index Filecoin chain state such as tipsets, messages, events and ETH transactions for accurate and faster RPC responses. The `ChainIndexer` replaces the existing `MsgIndex`, `EthTxHashLookup` and `EventIndex` implementations in Lotus, which [suffer from a multitude of known problems](https://github.com/filecoin-project/lotus/issues/12293).  If you are an RPC provider or a node operator who uses or exposes Ethereum and/or events APIs, please refer to the [ChainIndexer documentation for operators](./documentation/en/chain-indexer-overview-for-operators.md) for information on how to enable, configure and use the new Indexer.  While there is no automated data migration and one can upgrade and downgrade without backups, there are manual steps that need to be taken to backfill data when upgrading to this Lotus version, or downgrading to the previous version without ChainIndexer. Please be aware that that this feature removes some options in the Lotus configuration file, if these have been set, Lotus will report an error when starting. See the documentation for more information.
-- Update `EthGetBlockByNumber` to return a pointer to ethtypes.EthBlock or nil for null rounds. ([filecoin-project/lotus#12529](https://github.com/filecoin-project/lotus/pull/12529))
 - Reduce size of embedded genesis CAR files by removing WASM actor blocks and compressing with zstd. This reduces the `lotus` binary size by approximately 10 MiB. ([filecoin-project/lotus#12439](https://github.com/filecoin-project/lotus/pull/12439))
 - Add ChainSafe operated Calibration archival node to the bootstrap list ([filecoin-project/lotus#12517](https://github.com/filecoin-project/lotus/pull/12517))
 - `lotus chain head` now supports a `--height` flag to print just the epoch number of the current chain head ([filecoin-project/lotus#12609](https://github.com/filecoin-project/lotus/pull/12609))
