-This is the first release candidate for the upcoming MANDATORY 1.20.0 release of Lotus. This release will deliver the Hygge network upgrade, introducing Filecoin network version 18. The centerpiece of the upgrade is the introduction of the [Filecoin Virtual Machine (FVM)’s Milestone 2.1](https://fvm.filecoin.io/), which will allow for EVM-compatible contracts to be deployed on the Filecoin network.

 ## Filecoin Ethereum Virtual Machine (FEVM)
 
 The Filecoin Ethereum Virtual Machine (FEVM) is built on top of the WASM-based execution environment introduced in the Skyr v16 upgrade. The chief feature introduced is the ability for anyone participating in the Filecoin network to deploy their own EVM-compatible contracts onto the blockchain, and invoke them as appropriate.

 Most of the Eth APIs take Eth accounts and tx has as an input, and they start with `0x` , and that is what Ethereum tooling support. However, in Filecoin, we have Filecoin account formats where things start with `f` (`f410` specifically for eth accounts on Filecoin) and the messages are in the format of CIDs. To enable a smooth developer experience, Lotus internally converts between Ethereum address and Filecoin account address as needed. In addition, lotus also keeps a Eth tx hash <> Filecoin message CID map and stores them in a SQLite database as node sees a FEVM messages. The database is initiated and the maps are populated  automatically in `~/<lotus_repo>/sqlite/txhash.db` for any node that as Eth RPC enabled. Node operators can configure how many historical mappings they wanna store by configuring `EthTxHashMappingLifetimeDays` .
 
-**Events***
+**Events**
 
 [FIP-0049 introduces actor events](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0049.md) that can be emitted and externally observable during message execution. An `events.db` is created automatically under `~/<lotus_repo>/sqlite` to store these events if the node has Eth RPC enabled. Node operators can configure the events support base on their needs by configuration `Events` configurations.
 
 Note: All three features are new and we welcome user feedbacks, create an issue if you have any enhancements that you’d like to see!
