 ## Update Fullnode With New Releases
 
+:::info ✨ Devnet New Address Format ✨
+Aptos addresses are now 32-bytes instead of 16-bytes. If you added seed peers before, make sure you update them to the new 32-bytes format. <br/>
+For people who are using static identity, you can regenerate your identity following the same instruction [Create a static identity for a FullNode](#create-a-static-identity-for-a-fullnode) above.
+:::info

 When `devnet` is wiped and updated with newer versions, you will need to update your FullNode as well. If you don't,
 it will not continue to synchronize with the network. To do this, follow these steps:
 1. Shutdown your fullnode.
