+
+    As a leader, the replication progress to itself should be restored upon
+    startup.
+
+    And if this leader is the only node in a cluster, it should re-apply all
+    of the logs to state machine at once.

+
+    Before this commit `RaftMetrics.snapshot` contains the last log id of a
+    snapshot that is **going** to install. Therefore there is chance the
+    metrics is updated but the store does not.
+
+    In this commit, `RaftMetrics.snapshot` will only be updated when a
+    snapshot is finished building or installing, by adding a new field
+    `snpashot` to `IOState` for tracking persisted snapshot meta data.
+
+    - Fix: #912

+
+    When streaming a snapshot chunk, it should repeatly `read_buf()` until
+    `snapshot_max_chunk_size` is full or read EOF.
+
+-   Fixed: [2c715d6e](https://github.com/datafuselabs/openraft/commit/2c715d6e6673a11e96ea157509aefc42e1438330) End `tick_loop()` when the receiver is gone.; by Ivan Schréter; 2023-11-13
+
+    Currently, `tick_loop()` would keep printing the trace message every
+    tick even when the receiver (Raft main loop) is gone in this form:
+
+    `INFO openraft::core::tick: .../tick.rs:70: Tick fails to send, receiving end quit: channel closed`
+
+    If the tick message fails to send, then terminate the loop, since every
+    future message will fail to send as well.
+
+    Also adjust the trace message to better describe what happened.
