 The Lotus v1.31.0 release introduces the new `ChainIndexer` subsystem, enhancing the indexing of Filecoin chain state for improved RPC performance. Several bug fixes in the block production loop are also included. Please review the upgrade warnings and documentation for any important changes affecting RPC providers, node operators and storage providers.
 
 ## ⭐ New Feature Highlights:
-- 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

 - `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))
 - Implement `EthGetTransactionByBlockNumberAndIndex` (`eth_getTransactionByBlockNumberAndIndex`) and `EthGetTransactionByBlockHashAndIndex` (`eth_getTransactionByBlockHashAndIndex`) methods. ([filecoin-project/lotus#12618](https://github.com/filecoin-project/lotus/pull/12618))
 - `lotus-shed indexes inspect-indexes` now performs a comprehensive comparison of the event index data for each message by comparing the AMT root CID from the message receipt with the root of a reconstructed AMT. Previously `inspect-indexes` simply compared event counts.  Comparing AMT roots instead confirms all the event data is byte-perfect.

 # Why does Filecoin mining work best on AMD?
 Currently, Filecoin's Proof of Replication (PoRep) prefers to be run on AMD

 competitively fast on some ARM processors, like the ones in newer Samsung
 phones, but they lack the RAM to seal the larger sector sizes). The main reason
 that we see this benefit on AMD processors is due to their implementation of
