<Aside type="caution" title="Upgrade Time-Based Upkeep Recommended">
  The Automation “Time-based” upkeep contract has been updated so that only the unique forwarder for your upkeep can call it. If your upkeep was deployed before 11 December 2025, we recommend you replace your existing “Time-based” upkeeps using the new “Time-based” upkeep.

To upgrade, simply follow the [Automation UI](https://automation.chain.link/) to register a new “Time-based” upkeep with the same details as your previous upkeep. Once registered, you can delete the previous upkeep.

Upgrading to the latest “Time-based” upkeep removes i) the ability of 3rd parties to trigger your upkeep, and ii) the possibility that a call with insufficient gas ticks the Timer forward but fails to execute your desired function.
