 - Expose APIs to list the miner IDs that are currently participating in F3 via node. ([filecoin-project/lotus#12608](https://github.com/filecoin-project/lotus/pull/12608))
 - Implement new `lotus f3` CLI commands to list F3 participants, dump manifest, get/list finality certificates and check the F3 status. ([filecoin-project/lotus#12617](https://github.com/filecoin-project/lotus/pull/12617), [filecoin-project/lotus#12627](https://github.com/filecoin-project/lotus/pull/12627))
 - Return a `"data"` field on the `"error"` returned from RPC when `eth_call` and `eth_estimateGas` APIs encounter `execution reverted` errors. ([filecoin-project/lotus#12553](https://github.com/filecoin-project/lotus/pull/12553))
+- Implement `EthGetTransactionByBlockNumberAndIndex` (`eth_getTransactionByBlockNumberAndIndex`) and `EthGetTransactionByBlockHashAndIndex` (`eth_getTransactionByBlockHashAndIndex`) methods. ([filecoin-project/lotus#12618](https://github.com/filecoin-project/lotus/pull/12618))
 
 ## Bug Fixes
 - Fix a bug in the `lotus-shed indexes backfill-events` command that may result in either duplicate events being backfilled where there are existing events (such an operation *should* be idempotent) or events erroneously having duplicate `logIndex` values when queried via ETH APIs. ([filecoin-project/lotus#12567](https://github.com/filecoin-project/lotus/pull/12567))
