+- **All mainnet node operators that are on a version lower the v1.26.x, must upgrade to this patch release before 2024-04-24T14:00:00Z.**
 
 This patch also includes fixes for node operators who want to index builtin-actor events after the nv22 upgrade. Specifically, it ensures the builtin actor event entries are ordered by insertion order when selected ([#11834](https://github.com/filecoin-project/lotus/pull/11834)). It also includes a couple Lotus-Miner patch fixes, ensuring that SnapDeals works properly and are using the new ProveReplicaUpdate3 message after the network version 22 upgrade, ensuring that DDO-sectors has the correct sector expirations, as well as DDO-sector visibility in the `lotus-miner sectors list` cmd.
