+
+- Fix `isFunction` signature to assert `Function`
+
+## 2.12.1 Jun 1, 2020
+
+- **Important** Removed `mnemonicToSeed`, it is only for bip39, use `mnemonicToMiniSecret` for the Substrate variant
+- Added `u8aEq` to compare two Uint8Array or hex values for an exact match
+- Added `addressEq` to compare two addresses (ss58, Uint8array or hex) for an exact match
+- Throw error on `{nacl,schnorrkel}Verify` on invalid input lengths
+- Performance optimizations in `u8aToHex` & `u8aConcat`
+
+## 2.11.1 May 26, 2020
