+#### Trie.prove renamed to Trie.createProof
+
+To clarify the method's purpose `Trie.prove` has been renamed to `Trie.createProof`. `Trie.prove` has been deprecated but will remain as an alias for `Trie.createProof` until removed.
+
 #### Trie raw methods
 
 `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.

+This is an implementation of the modified merkle patricia tree as specified in the [Ethereum Yellow Paper](http://gavwood.com/Paper.pdf):
 
 > The modified Merkle Patricia tree (trie) provides a persistent data structure to map between arbitrary-length binary data (byte arrays). It is defined in terms of a mutable data structure to map between 256-bit binary fragments and arbitrary-length binary data. The core of the trie, and its sole requirement in terms of the protocol specification is to provide a single 32-byte value that identifies a given set of key-value pairs.
