+
+## ☢️ Upgrade Warnings ☢️
+
+This feature release requires a minimum Go version of v1.20.7 or higher to successfully build Lotus. Go version 1.21.x is not supported yet.
+
+## v12 Builtin Actor Bundles
+
+[Builtin actor v12.0.0](https://github.com/filecoin-project/builtin-actors/releases/tag/v12.0.0) is used for supporting this upgrade.
+Make sure that your lotus actor bundle matches the v12 actors manifest by running the following cli after upgrading:
+
+```

+
+## Migration  
+
+We are expecting a heavier than normal state migration for this upgrade due to the amount of state changes introduced for miner sector info. (This is a similar migration as the Shark upgrade, however, we have introduced a couple of migration performance optimizations since then for a smoother upgrade experience.)
+
+All node operators, including storage providers, should be aware that ONE pre-migration is being scheduled 180 epochs before the upgrade, around 2023-12-12T12:00:00Z. It will take around 20-30 minutes for the pre-migration and less than 30 seconds for the final migration, depending on the amount of historical state in the node blockstore and the hardware specs the node is running on. During this time, expect slower block validation times, increased CPU and memory usage, and longer delays for API queries (during our testing, it topped out about 205 RAM(htop) on a 1TiB box).
+
+We recommend node operators (who haven't enabled splitstore `discard` mode) that do not care about historical chain states, to prune the chain blockstore by syncing from a snapshot 1-2 days before the upgrade.
+
+Note to full archival node operators: you may expect it takes some time  for the node to complete the final migration, during this period your node will fall out of sync and your chain service may have some disruption. However, you can expect the node to catch up soon after the migration completes. You can test out the migration by running the following on your node in offline mode:
+
+1. `lotus chain head | head -n1`
+2. Stop Lotus daemon
+3. `./lotus-shed migrate-state --repo=[path-to-your-lotus-repo] 21 [output-of-step-1]`
+
+You can check out the [tutorial for benchmarking the network migration here.](https://lotus.filecoin.io/kb/test-migration/)
+
+
+## BREAKING CHANGE
+
+There is a new protocol limit on how many partition could be submited in one PoSt - if you have any customized tooling for batching PoSts, please update accordingly. 
+- feat: limit PoSted partitions to 3 ([filecoin-project/lotus#11327](https://github.com/filecoin-project/lotus/pull/11327))
+
+## New features
+- Implement and support [FIP0052: Increase Max Sector Commitment to 3.5 years](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0052.md)
+   - fix: docs: Update SectorLifetime to be in line with FIP-0052 ([filecoin-project/lotus#11314](https://github.com/filecoin-project/lotus/pull/11314))
+- Implement and support [FIP0059: Synthetic PoRep](https://github.com/filecoin-project/FIPs/blob/master/FIPS/fip-0059.md) - Check out the [Lotus documentation for Synthetic PoRep](https://lotus.filecoin.io/storage-providers/advanced-configurations/sealing/#synthetic-porep).
+   - feat: implement Synthetic PoRep ([filecoin-project/lotus#11258](https://github.com/filecoin-project/lotus/pull/11258))
+   - chore: config: Update todo in UseSyntheticPoRep ([filecoin-project/lotus#11297](https://github.com/filecoin-project/lotus/pull/11297))
+   
+## Improvements
+- Backport: feat: sealing: Switch to calling PreCommitSectorBatch2 ([filecoin-project/lotus#11215](https://github.com/filecoin-project/lotus/pull/11215))
+- updated the boostrap nodes 
+
+## Dependencies
+- github.com/filecoin-project/go-amt-ipld/v4 (v4.0.0 -> v4.2.0)
+- chore: deps: update FFI, FVM, and actors ([filecoin-project/lotus#11310](https://github.com/filecoin-project/lotus/pull/11310))
+- chore: deps: update to final actors ([filecoin-project/lotus#11330](https://github.com/filecoin-project/lotus/pull/11440))
+- chore: deps: update to go-state-types v0.12.8 ([filecoin-project/lotus#11339](https://github.com/filecoin-project/lotus/pull/11437))
+- chore: deps: update libp2p to v0.30.0 #11434
+
+
+## Snapshots 
+
+The [Forest team](https://filecoinproject.slack.com/archives/C029LPZ5N73) at Chainsafe has launched a brand new lightweight snapshot service that is backed up by forest nodes! This is a great alternative service along with the fil-infra one, and it is compatible with lotus! We recommend lotus users to check it out [here](https://docs.filecoin.io/networks/mainnet#resources)!
