 - Return a "data" field on the "error" returned from RPC when `eth_call` and `eth_estimateGas` APIs encounter `execution reverted` errors. This is a standard expectation of Ethereum RPC tooling and may improve compatibility in some cases. ([filecoin-project/lotus#12553](https://github.com/filecoin-project/lotus/pull/12553))

 - Implement F3 utility CLIs to list the power table for a given instance and sum the proportional power of a set of actors that participate in a given instance. ([filecoin-project/lotus#12698](https://github.com/filecoin-project/lotus/pull/12698))

 ## 🐛 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.
