 This implies every contract has to be deployed before it can be tested (via `env.deploy` or `env.deploy_self`) and of course it has to be recompiled if its code was changed before TXE can use the modified bytecode.
 
+### Address is now a point
+The address now serves as someone's public key to encrypt incoming notes. An address point has a corresponding address secret, which is used to decrypt the notes encrypted with the address point.
+
+### Notes no longer store a hash of the nullifier public keys, and now store addresses
+Because of removing key rotation, we can now store addresses as the owner of a note. Because of this and the above change, we can remove registering a recipient, because now we do not need any keys of the recipient.

 ### [l1-contracts] Inbox's MessageSent event emits global tree index
 Earlier `MessageSent` event in Inbox emitted a subtree index (index of the message in the subtree of the l2Block). But the nodes and Aztec.nr expects the index in the global L1_TO_L2_MESSAGES_TREE. So to make it easier to parse this, Inbox now emits this global index.
