Optimism has announced that it will cease support for op-geth and op-program on May 31st.

BlockBeats News, March 5th, according to official sources, Optimism announced that it will end support for 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 occur on op-reth. The fault proof mechanism of op-program will also be migrated to kona-client, and the current deployment is expected to continue to be used before the Karst hard fork.

Chain operators should complete the migration during the Karst hard fork; otherwise, chains still running op-geth will be unable to follow the main chain. cannon-kona can run in the existing op-node environment without using kona-node, as kona-node is an optional component. Node operators should migrate to op-reth as soon as possible to maintain network compatibility and access new feature support.
