 Besu <> Orion node pairs, when upgrading Besu to v1.5, it is required that Orion is upgraded to 
 v1.6. Older versions of Orion will no longer work with Besu v1.5.  
 
+## 1.5 Features 
+
+Features added between from 1.4 to 1.5 include: 
+* Mining Support 
+  Besu supports `eth_hashrate` and `eth_submitHashrate` to obtain the hashrate when we mine with a GPU mining worker. 
+* Tracing 
+  The [Tracing API](https://besu.hyperledger.org/en/latest/Reference/API-Methods/#trace-methods) is no longer an Early Access feature and now has full support for `trace_replayBlockTransactions`, `trace_Block` and `trace_transaction`.  
+* Plugin API Block Events 
+  `BlockAdded` and `BlockReorg` are now exposed via the [Plugin API](https://javadoc.io/doc/org.hyperledger.besu/plugin-api/latest/org/hyperledger/besu/plugin/services/BesuEvents.html). 
+* [Filters](https://besu.hyperledger.org/en/stable/HowTo/Interact/Filters/Accessing-Logs-Using-JSON-RPC/) and 
+  [subscriptions](https://besu.hyperledger.org/en/stable/HowTo/Interact/APIs/RPC-PubSub/) for private contracts.  
+* [SecurityModule Plugin API](https://javadoc.io/doc/org.hyperledger.besu/plugin-api/latest/org/hyperledger/besu/plugin/services/SecurityModuleService.html)
+  This allows use of a different [security module](https://besu.hyperledger.org/en/stable/Reference/CLI/CLI-Syntax/#security-module) 
+  as a plugin to provide cryptographic function that can be used by NodeKey (such as sign, ECDHKeyAgreement etc.). 
+* [Onchain privacy groups](https://besu.hyperledger.org/en/latest/Concepts/Privacy/Onchain-PrivacyGroups/)
+  with add and remove members. This is an early access feature. Early access features are not recommended
+  for production networks and may have unstable interfaces.

 ### Additions and Improvements

 * Public Networks Default to Fast Sync: The default sync mode for named permissionless networks, such as the Ethereum mainnet and testnets, is now `FAST`.
   * The default is unchanged for private networks. That is, the sync mode defaults to `FULL` for private networks. 
   * Use the [`--sync-mode` command line option](https://besu.hyperledger.org/Reference/CLI/CLI-Syntax/#sync-mode) to change the sync mode. [\#384](https://github.com/hyperledger/besu/pull/384)
-* Proper Mining Support: Added full support for `eth_hashrate` and `eth_submitHashrate`. It is now possible to have the hahsrate when we mine with a GPU mining worker [\#1063](https://github.com/hyperledger/besu/pull/1063)

 * Performance Improvements: The addition of native libraries ([\#775](https://github.com/hyperledger/besu/pull/775)) and changes to data structures in the EVM ([\#1089](https://github.com/hyperledger/besu/pull/1089)) have improved Besu sync and EVM execution times.

+* Added experimental CLI option `--Xnat-kube-pod-name` to specify the name of the loadbalancer used by the Kubernetes nat manager [\#1078](https://github.com/hyperledger/besu/pull/1078)
+- Local permissioning TOML config now supports additional keys (`nodes-allowlist` and `accounts-allowlist`). 
+Support for `nodes-whitelist` and `accounts-whitelist` will be removed in a future release. 
+- Add missing `mixHash` field for `eth_getBlockBy*` JSON RPC endpoints. [\#1098](https://github.com/hyperledger/besu/pull/1098)
 * Besu now has a strict check on private transactions to ensure the privateFrom in the transaction
 matches the sender Orion key that has distributed the payload. Besu 1.5+ requires Orion 1.6+ to work.
