 # CHANGELOG
 
+## 5.9.1 Feb 28, 2021
+
+Changes:
+
+- Expand `detectPackage` with optional param allowing checks for monorepo versions
+- Export logger `format` function directly as `loggerFormat`
+- Expand tests and checks for `hdValidatePath`
+- Remove `hdEthereum` class-based approach, simplify
+- Cleanup formatting on nested conditionals in the `@polkadot/x-` packages
+- All packages now export `packageInfo` from the root
+
+
+## 5.8.1 Feb 26, 2021
+
+Contributed:
+
+- Add ss58 information for HydraDX (Thanks to https://github.com/jak-pan)
+- HD derivation for Ethereum (Thanks to https://github.com/joelamouche)
+
+Changes:
+
+- Adjust base64 encoding/decoding to not rely on Buffer being available
+- Rework Ethereum derivation to only use Uint8Array internally
+- Shared HD path validation for Ledger & Ethereum
+- Additional derivation, encoding and decoding tests on keyring
+- Align networks with upstream ss58 registry
+- `@polkadot/wasm-crypto` 3.2.4
+
+
+## 5.7.1 Feb 21, 2021
+
+**Breaking change** The signature of `pair.verify` now requires the signer public key as a parameter. If using `pair.verify` pass the publicKey (hex or Uint8Array) of the signer.
+
+Changes:
+
+- The signature on the keyring for `.verify` now explicitly requires the `publicKey` of the signer. Previously it only verified against an own public key.
+- Add additional ss58 test vectors (against chains with >63 prefixes in the Substrate registry)
+
+
+## 5.6.3 Feb 16, 2021
+
+Contributed:
+
+- Add ss58 information for Aventus (Thanks to https://github.com/nahuseyoum)
+
+Changes:
+
+- Add `unlock(password)` to keypair (less confusing than only having `decodePkcs8`, equivalent to `lock()`)
+- Change use of `detectPackage` to use `packageInfo.ts`
+- Align with upstream ss58 registry
+- `@polkadot/wasm-crypto` 3.2.3
+
+
+## 5.6.2 Feb 8, 2021
+
+Changes:
+
+- `@polkadot/networks` now filters the new upstream-introduced `null` networks
+
+
+## 5.6.1 Feb 7, 2021
+
+Contributed:
+
+- Fix installation instructions in `@polkadot/x-global` (Thanks to https://github.com/raoulmillais)
+
+Changes:
+
+- Conform to new ss58 encoding with ids up to 16,383 (>= 64 as 2 bytes)
+- Use JS sqrt inside `bnSqrt` when value <= MAX_SAFE_INTEGER
+- Adjust all `Buffer.from` usages, prefer `Uint8Array` where possible
+- Expand tests for keyring with `vrf{Sign, Verify}`
+- Align `@polkadot/networks` with latest ss58 registry
+
+
