-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. This upgrade delivers user-programmablity to the Filecoin network for the first time!

-Note that this release candidate does NOT set the epoch at which mainnet will upgrade; that detail will be finalized in the 1.20.0 release.
+The Filecoin mainnet is scheduled to upgrade to nv18 at epoch 2683348, on March 14th at 2023-03-14T15:14:00Z. All node operators, including storage providers, must upgrade to this release before that time. Storage providers must update their daemons, miners, market and worker(s)/boost.
+At the upgrade, a short migration will run that converts code actors v9 code CIDs to v10 CIDs, and installs the new Ethereum Address Manager singleton (see below). This is expected to be a lightweight migration that causes no service disruption.
 
-The Hygge upgrade introduces the following Filecoin Improvement Proposals (FIPs), delivered in FVM3 (see FVM [v3.0.0-rc.1](https://github.com/filecoin-project/ref-fvm/pull/1664)) and builtin-actors v10 (see actors [v1.10.0-rc.1](https://github.com/filecoin-project/builtin-actors/releases/tag/v10.0.0-rc.1)):

 The creation of EVM actors is managed by **the new** [Ethereum Address Manager actor (EAM)](https://github.com/filecoin-project/builtin-actors/tree/master/actors/eam), a singleton that is invoked in order to deploy EVM actors. In order to make usage of the FEVM as seamless as possible for users familiar with the Ethereum ecosystem, this upgrades also introduces **a dedicated actor to serve as “[Ethereum Accounts](https://github.com/filecoin-project/builtin-actors/tree/master/actors/ethaccount)”**. This actor exists to allow for secp keys to be used in the Ethereum addressing scheme. **The last new built-in actor introduced is [the Placeholder actor](https://github.com/filecoin-project/builtin-actors/tree/master/actors/placeholder)**, a thin “shell” of an actor that can transform into either EVM or EthAccount actors. For more on the EAM, EthAccount, and Placeholder actors, please see [FIP-0055](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0055.md).

-This release candidate sets the calibration-net nv18 Hygge upgrade at epoch 322354, 22023-02-21T16:30:00Z. The bundle the network will be using is [v10.0.0 actors](https://github.com/filecoin-project/builtin-actors/releases/tag/v10.0.0-rc.1)

+### v10 Built-in actor bundles
+
+Bundles for all networks (mainnet, calibnet, etc.) are included in the lotus source tree (`build/actors/`) and embedded on build, for v10 actors you can find it [here](https://github.com/filecoin-project/lotus/blob/master/build/actors/v10.tar.zst). 
+Reminder: Lotus verifies that the bundle CIDs are the right ones upon build & upgrade against the values in `build/builtin_actors_gen.go`, according to the network you are building. You may also check the bundle manifest CID matches the bundle gen-ed values by running `lotus state actor-cids --network-version 18`.

 ## Node Operators
 
 FVM has been running in lotus since v1.16.0 and up, and the new FEVM does not increase any node hardware spec requirement.
 
-With FEVM on Filecoin, we aim to provide full compatibility with the existing EVM ecosystem and its tooling out of box and thus, lotus now provides a full set of [Ethereum-styled APIs](https://github.com/filecoin-project/lotus/blob/release/v1.20.0/node/impl/full/eth.go) for developers and token holders to interact with the Filecoin network as well.

+For full documentation on this new tooling, please see the [Lotus docs website](https://lotus.filecoin.io/lotus/configure/ethereum-rpc/).
 
-**Enable Ethereum JSON RPC API**
+**Enabling Ethereum JSON RPC API**
 
 Note that Ethereum APIs are only supported in the lotus v1 API, meaning that any node operator who wants to enable Eth API services must be using the v1 API, instead of the v0 API. To enable Eth RPC, simply set `EnableEthRPC` to `true` in your node config.toml file; or set env var `LOTUS_FEVM_ENABLEETHRPC` to `1` before starting your lotus node.
 
 **Eth tx hash and Filecoin message CID**
 
 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.
