 # UNRELEASED
 - chore: Auto remove local chain data when importing chain file or snapshot ([filecoin-project/lotus#11277](https://github.com/filecoin-project/lotus/pull/11277))
 - feat: metric: export Mpool message count ([filecoin-project/lotus#11361](https://github.com/filecoin-project/lotus/pull/11361))
+- feat: sealing: load SectorsSummary from sealing SectorStats instead of calling API each time ([filecoin-project/lotus#11353](https://github.com/filecoin-project/lotus/pull/11353))
 
 ## New features
 - feat: Added new tracing API (**HIGHLY EXPERIMENTAL**) supporting two RPC methods: `trace_block` and `trace_replayBlockTransactions` ([filecoin-project/lotus#11100](https://github.com/filecoin-project/lotus/pull/11100))
