Scheduled

We are updating our Sei Atlantic Testnet nodes to v6.4.0, as part of Testnet Proposal #245, with upgrade height of 239866529 (ETA ~2026-04-06 16:00:00 UTC).

RPC / API Changes
- eth_getLogs modified Performance improved with early rejection and backpressure (PR #2591). No interface change, but behavior under load is different.
- All RPC HTTP endpoints modified RPC HTTP requests now use POST instead of GET (PR #2675). Clients using GET will break.
- debug_traceBlock / profiled block tracing modified Profiled block tracing is now opt-in by default (PR #3189). Previously it may have been enabled by default.
