Pi Network has issued an official notice to node operators, requiring them to complete the mandatory upgrade to protocol version 22.1 (v22.1) by April 27, 2026; otherwise, they face the risk of their nodes being disconnected from the network.

Currently, the system is running on version 21.2; the next step is to upgrade to v22.1, without skipping any version.

According to an official notice from Pi Network, the v22.1 upgrade for this release is a mandatory operation, with the deadline being April 27, 2026. Version upgrades must be performed step by step in order, from the current v21.2 to v22.1, without skipping any version, because each version is built on top of the previous one.
Pi Network states that this upgrade is intended to improve system stability and performance, and to lay the infrastructure groundwork for the next stage of protocol version 23.0 (v23.0); v23.0 is expected to introduce smart contract functionality.
Upgrade Operation Guidelines and Expected Downtime
According to the official notice from Pi Network, the v22.1 upgrade for most nodes is expected to take no more than 15 minutes. Pi Network recommends that operators gradually shift node traffic during the upgrade process, avoiding upgrading all nodes at the same time to ensure service continuity. Pi Network has also released tools to help automate future upgrade workflows, which are suitable for advanced users.
Consequences of Not Upgrading
According to the official notice from Pi Network, nodes that fail to complete the upgrade before the April 27, 2026 deadline will face the risk of being disconnected from the network, will be unable to continue participating in the active network, and may miss subsequent version updates and smart contract functionality.
