Octez version 16.1 has just been released.
This version fixes an implementation bug in the new Mumbai baker binary that could lead to bakers occasionally failing to endorse blocks correctly, and could result in deterioration in network liveness.
Hence, we strongly recommend bakers to upgrade to v16.1. before the activation of Mumbai on block #3,268,609.
Notice that this new release ships the same PtMumbai2 protocol than Octez v16.0.
Full changelog and update instructions are available in the version 16 release page:
Version 16.1 — Tezos (master branch, 2023/03/23 20:05) documentation
