- [PR #620](https://github.com/rqlite/rqlite/pull/620): Log level can be specified for Raft module.

## 5.0.0 (December 30th 2019)
This release uses a new Raft consensus version, with the move to Hashicorp Raft v1. As a result **the Raft system in 5.0 is not compatible with the 4.0 series**. To upgrade from an earlier version to this release you should backup your 4.0 leader node, and restore the database dump into a new 5.0 cluster.

The rqlite server also supports explicitly setting the node ID. While it's not required to set this, it's recommended for production clusters. See the [cluster documentation](https://github.com/rqlite/rqlite/blob/master/DOC/CLUSTER_MGMT.md) for more details.

The HTTP Query and Insert API remains unchanged in the 5.0 series relative to the 4.0 series.
