 ## 🐛 Bug Fix Highlights
 - Add logic to check if the miner's owner address is delegated (f4 address). If it is delegated, the `lotus-shed sectors termination-estimate` command now sends the termination state call using the worker ID. This fix resolves the issue where termination-estimate did not function correctly for miners with delegated owner addresses. ([filecoin-project/lotus#12569](https://github.com/filecoin-project/lotus/pull/12569))
 - The Lotus Miner will now always mine on the latest chain head returned by lotus, even if that head has less "weight" than the previously seen head. This is necessary because F3 may end up finalizing a tipset with a lower weight, although this situation should be rare on the Filecoin mainnet. ([filecoin-project/lotus#12659](https://github.com/filecoin-project/lotus/pull/12659)) and ([filecoin-project/lotus#12690](https://github.com/filecoin-project/lotus/pull/12690))
