 - 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. ([filecoin-project/lotus#12570](https://github.com/filecoin-project/lotus/pull/12570))
 - 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))

 - Make the ordering of event output for `eth_` APIs and `GetActorEventsRaw` consistent, sorting ascending on: epoch, message index, event index and original event entry order. ([filecoin-project/lotus#12623](https://github.com/filecoin-project/lotus/pull/12623))
 - Event APIs (Eth events and actor events) should only return reverted events if client queries by specific block hash / tipset. Eth and actor event subscription APIs should always return reverted events to enable accurate observation of real-time changes. ([filecoin-project/lotus#12585](https://github.com/filecoin-project/lotus/pull/12585))
 - 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))
+- Correct erroneous sector QAP-calculation upon sector extension in lotus-miner cli. ([filecoin-project/lotus#12698](https://github.com/filecoin-project/lotus/pull/12720))
