+SDK Core| v0.16.4 | https://www.npmjs.com/package/nem2-sdk
+Catbuffer Library| v0.0.11 | https://www.npmjs.com/package/catbuffer

+- Core 0.9.2.1 compatible. Changed hash algorithm for shared key derivation to `HKDF-HMAC-Sha256`.
+- Removed `senderPrivateKey` in `Persistent Delegation Request Transaction`. Instead, it uses an `ephemeral key pair` and the `EphemeralPublicKey` is now attached in the `PersistentDelegationMessage` payload.
+- Removed `salt` encryption and decryption functions which uses `HKDF-HMAC-Sha256` instead. This only affects the encrypted payload.
+- Added missing export in `Infrastructure` classes / interfaces.
+- Applied latest `catbuffer` builder codes for `ResolutionStatement`.
+- Updated `TransactionType` & `TransactionVersion` enum key name to match `catabuffer` schema definition.
+- Changed signature type for `Height` from `numeric string` to `UInt64` in `Block` & `Receipt` respostiories
+- Fixed a few ts lint issues.
