Scheduled

We are upgrading our Flow Testnet EVM Gateway infrastructure to v1.5.7.

This release finalizes the fix for a transaction handling issue and transitions the infrastructure to batch-mode transaction processing as the long-term standard.

The Go toolchain has been bumped to 1.26 and flow-go dependencies have been updated.

During the maintenance window, brief interruptions to RPC availability may occur.
