+### P2P and Network Changes
+
+Support for the legacy ElGamal (type 0) encryption type when creating I2P
+sessions is being sunset by the I2P network and will be removed from bitcoind on
+or before v34. Nodes using I2P with versions of Bitcoin Core earlier than v26.1
+(PRs #29200, #29209) will soon only be able to connect to other legacy ElGamal
+I2P peers and will be increasingly isolated from the rest of the network, with a
+reduced anonymity set. See #35696 for details.
