Overview

Note

This is a recommended release that includes security updates and one breaking RPC field removal.

cross_unsafe_l2 removed from optimism_syncStatus (#22555). The cross-unsafe head byte-for-byte mirrored the unsafe head and is gone from the RPC response and from eth.SyncStatus. Dashboards, alerts, and tooling reading cross_unsafe_l2 must switch to unsafe_l2; Go JSON clients tolerate the absent field. The message-safety level named cross-unsafe is a separate concept and is unchanged.

New World Chain Karst activation times (#22624). The embedded superchain registry gains:
- sepolia/worldchain — karst_time = 1788868800 (Tue 8 Sep 2026 12:00:00 UTC)
- mainnet/worldchain — karst_time = 1789992000 (Mon 21 Sep 2026 12:00:00 UTC)
An op-supernode managing World Chain from the embedded registry on an earlier release will not activate Karst and will diverge from the chain. No other chain's activation times change in this release.

Security updates cover the Go 1.26.6 toolchain, golang.org/x/crypto v0.56.0, golang.org/x/mod v0.40.0, and the Pion STUN/DTLS dependency transition, including the op-geth bump that moves its NAT/STUN path to Pion v3 (#22424, #22750, #22425, #22180, #22181, #22069, #22694)
