 # Changelog
 
+## 1.4.5
+
+### Additions and Improvements
+
+ - Introduced SecurityModule plugin API. This allows use of a different security module as a plugin to 
+ provide cryptographic function that can be used by NodeKey (such as sign, ECDHKeyAgreement etc.). KeyPairSecurityModule
+  is registered and used by default. The CLI option `--security-module=<name> (defaults to localfile)` can be used 
+  to identify the security module plugin name to use instead. [\#713](https://github.com/hyperledger/besu/pull/713)
