 # CHANGELOG
 
+## 3.4.1 Aug 31, 2020
+
+- Allow for WASM-as-available `mnemonicToBip39` call (used for Ethereum-compatible keypairs)
+- Add `isWasm` utility to check for valid WASM headers
+- `@polkadot/wasm-crypto` 1.4.1
+
+## 3.3.1 Aug 24, 2020
+
+- Add `addressRaw` to Keyring interface (if address encoding is different to publicKey)
+- Allow for Ethereum pair signing and verification
+
+## 3.2.1 Aug 17, 2020
+
+- Allow for (optional, default blake2) hasher to secp256k1 sign/verify functions
+- Utilities for secp256k1 publicKey expansion and compression
+- Add basic Ethereum address utils (encode with checksum & checksum verification)
+- Add Ethereum-compatible `mnemonicToBip39` seed creation function
+
+## 3.1.1 Aug 10, 2020
+
+- Add `deriveAddress(<address>, '/<soft>/<soft-b>')` via sr25519 soft
+- Use `scrypt` from WASM as available (JS fallback in place)
+- Add `base32{Encode, Decode}` utilities (IPFS-compatible alphabet)
+- Support IPFS compatibility flag in base58 encoding/decoding
+- Update to `@polkadot/wasm-crypto` 1.3.1
+
+## 3.0.1 Jul 27, 2020
+
+- Add Katal ss58Format (Thanks to https://github.com/retotrinkler)
+- Adjust JSON pair output with scrypt kdf (version 3 output)
+
+## 2.18.1 Jul 13, 2020
+
+- Add `base64{Decode, Encode, Validate}` as crypto utils
+- Extract `base58Validate` from base58 decode checks
+- Add `isAscii` to allow detection of printable ASCII sequences (including tab, newline)
+- Add `isUtf8` to allow detection of valid Utf8 sequences
+
+## 2.17.1 Jul 6, 2020
+
+- Add `encode{Derived, Multi}Address` to encode derived/multi addresses
+- Correctly handle 0 inputs in `numberToU8a`
+- Simplify and flatten base58 dependencies
+
+## 2.16.1 Jun 29, 2020
+
+- Adjust `addressCheck` and `encodeAddress` function to check for valid base58 alphabets (better error reporting)
+- Rename `createKeySub` to `createKeyDerived` based on changed in Substrate (sub keys now named derived)
+
+## 2.15.1 Jun 22, 2020
+
+- Adjust keyring to no override 0-prefix (Polkadot live) settings with keychain default
+
+## 2.14.1 Jun 16, 2020
+
+- Add `extractTime` utility conversion (Thanks to https://github.com/kwingram25)
+
+## 2.13.1 Jun 8, 2020
+
+- Fix JS blake2 fallback (non-wasm) to correctly deal with hex inputs
+- Align `bnToHex` signature with `bnToU8a` (with old/new style)
