🐛 Bug fixes
- 🛠 Fixed ImportSnapshot.
🆕 New features
- ➕ Added NodeHostConfig.RaftEventListener to allow user applications to be notified for certain Raft events.
👌 Improvements

- Immediately return ErrClusterNotReady when requests are dropped for not having a leader.
💥 Breaking changes
- ⬆️ When upgrading to v3.1.x from v3.0.x, dragonboat requires all streamed or imported snapshots to have been applied. github.com/lni/dragonboat/tools/upgrade310 is provided to check that. See the godoc in github.com/lni/dragonboat/tools/upgrade310 for more details. For users who use NodeHost.RequestSnapshot to export snapshots for backup purposes, we recommend to re-generate all exported snapshots once upgraded to v3.1.
