Scheduled

Following guidance from the Foundation to ensure all operators are running the latest supported software versions, we will perform an urgent upgrade of Stacks Mainnet stacks-node from v3.4.0.0.0 to v3.4.0.0.2 today at 12:00 UTC.

Current deployed versions:

* Stacks Node: v3.4.0.0.0 → v3.4.0.0.2

This release contains important stability and maintenance fixes for node operators.

No downtime is expected, but brief REST API or WebSocket interruptions may occur as services restart and resynchronize with the network.
