Reminder of action required for node operators:
Ensure your node is running Base Node v0.11.8 (released March 17) or higher to remain compatible with the upgrade. This is required to properly handle new events emitted from the SystemConfig contract.

Latest release: v0.12.2
https://github.com/base/node/releases

This reminder notice only applies to Base Node operators on mainnet. If you're not operating a Base Node on mainnet, no action is needed. Base will continue to operate as usual without issue during the upgrade.

Apr 14, 15:30 UTC
Scheduled - On April 14th, for approximately one hour at 15:30 UTC, the Optimism Collective will be conducting a canonical bridge withdrawal pause on testnets across the Superchain, including Base Sepolia testnet. Base mainnet, including canonical bridges on Base mainnet, will remain fully operational and completely unaffected during this pause. There is also no risk to user funds.

Testnet users will be completely unaffected unless actively attempting to withdraw using the canonical bridge on Base Sepolia testnet during the pause window. All other testnet activity will continue as usual.
