+# 0.2.1
+* Improve typespecs to allow for integers as a valid value to encode in RLP.
 # 0.2.0
 * Breaking: added option to encode RLP to either hex strings (`"8055FF"`) or binaries (`<<0x80, 0x55, 0xFF>`). The default is now `:binary`.
 * Added typespecs and additional test coverage through doctests.
