+Wallet
+------
+
+- Wallet loading has changed in this release. Wallets with some corrupted records that could be
+  previously loaded (with warnings) may no longer load. For example, wallets with corrupted
+  address book entries may no longer load. If this happens, it is recommended
+  load the wallet in a previous version of Bitcoin Core and import the data into a new wallet.
+  Please also report an issue to help improve the software and make wallet loading more robust
+  in these cases.
