 `getRaw`, `putRaw` and `delRaw` were deprecated in `v3.0.0` and have been removed from this release. Instead, please use `trie.db.get`, `trie.db.put`, and `trie.db.del`. If using a `SecureTrie` or `CheckpointTrie`, use `trie._maindb` to override the checkpointing mechanism and interact directly with the db.
 
+#### SecureTrie.copy
+
+`SecureTrie.copy` now includes checkpoint metadata by default. To maintain original behavior of _not_ copying checkpoint state, pass `false` to param `includeCheckpoints`.
