Optimism announced that it will stop supporting op-geth and op-program on May 31
According to official news, Optimism announced that it will stop supporting op-geth and op-program on May 31, 2026. During this period, security patches and critical bug fixes will still be released, but new feature development, including the next Karst hard fork, will only take place on op-reth. The fault proof program of op-program will also be migrated to kona-client, and the current deployment is expected to continue to be usable before the Karst hard fork.
Chain operators must complete the migration by the time of the Karst hard fork; otherwise, chains still running op-geth will not be able to follow the main chain. cannon-kona can run in the existing op-node environment without the need to use kona-node, which is an optional component. Node operators should migrate to op-reth as soon as possible to maintain network compatibility and receive support for new features.
