| - Added: [8b54a80f](https://github.com/datafuselabs/openraft/commit/8b54a80f6e5b06a181f12f55179e0928a470e21b) `Raft::config()` returns a ref to Config this raft node uses; by 张炎泼; 2024-03-14 | ||

| - Added: [7d5326ce](https://github.com/datafuselabs/openraft/commit/7d5326ce7b5534c93300eabbcefa0c4d3d45284e) add `RaftMetrics::millis_since_quorum_ack`; by 张炎泼; 2024-03-15 | ||
|
|
||
| `RaftMetrics::millis_since_quorum_ack` is the interval in milliseconds | ||
| since the last timestamp a quorum acknowledged. | ||
|
|
||
| This duration is used by the application to assess the likelihood that | ||
| the leader has lost synchronization with the cluster. | ||
| A longer duration without acknowledgment may suggest a higher | ||
| probability of the leader being partitioned from the cluster. | ||
|

|
||
| - Improved: [d4a3053f](https://github.com/datafuselabs/openraft/commit/d4a3053fa7b77fbe7db4fc7e598785b8f4d78676) Update example network err implementation; by Jonah Nestrick; 2024-03-15 | ||
|
|
||
| Update the example to return unreachable error for connection errors to | ||
| prevent immediate retries. | ||

|
|
||
| - Fixed: [17795e7f](https://github.com/datafuselabs/openraft/commit/17795e7f08bedc3417438aff2486fad261465225) Ensure heartbeat results are returned to `RaftCore`; by 张炎泼; 2024-03-17 | ||
|
|
||
| Previously, the heartbeat results were not sent back to | ||
| `RaftCore`, which requires these results to calculate the **last | ||
| timestamp acknowledged by a quorum**. | ||
|
|
||
| This commit resolves the issue by ensuring that the heartbeat RPC | ||
| results are sent back to `RaftCore`, allowing it to correctly update the | ||
| **last timestamp acknowledged by a quorum**. | ||

|
|
||
| This commit addresses an issue where `RaftMetrics` could be sent before | ||
| `RaftDataMetrics` and `RaftServerMetrics`. Since `Wait` relies solely on | ||
| `RaftMetrics` to reflect the latest state, it is crucial that | ||
| `RaftMetrics` are dispatched only after the other two metrics have been | ||
| updated. This change guarantees that once a change in `RaftMetrics` is | ||
| detected, it accurately represents the most recent changes from both | ||
| `RaftDataMetrics` and `RaftServerMetrics`. |
