 This feature release of Lotus includes numerous improvements and enhancements for node operators, ETH RPC-providers and storage providers.
 
 ## Highlights
 
+- [Lotus now includes a Slasher tool](https://github.com/filecoin-project/lotus/pull/10928) to monitor the network for Consensus Faults, and report them as appropriate
+  - The Slasher investigates all incoming blocks, and assesses whether they trigger any of the three Consensus Faults defined in the Filecoin protocol
+  - If any faults are detected, the Slasher sends a `ReportConsensusFault` message to the faulty miner
+  - For more information on the Slasher, including how to run it, please see LINK
 - The Ethereum-like RPC exposed by Lotus is now compatible with EIP-1898: https://github.com/filecoin-project/lotus/pull/10815
 - The lotus-miner PieceReader now supports parallel reads: https://github.com/filecoin-project/lotus/pull/10913
