 # UNRELEASED
 
+# 1.7.0 (June 5th, 2024)
+
+CHANGES
+
+* Raft multi version testing [GH-559](https://github.com/hashicorp/raft/pull/559)
+
+IMPROVEMENTS
+
+* Raft pre-vote extension implementation, activated by default. [GH-530](https://github.com/hashicorp/raft/pull/530)
+
+BUG FIXES
+
+* Fix serialize NetworkTransport data race on ServerAddr(). [GH-591](https://github.com/hashicorp/raft/pull/591)
+
+# 1.6.1 (January 8th, 2024)
+
+CHANGES
+
+* Add reference use of Hashicorp Raft. [GH-584](https://github.com/hashicorp/raft/pull/584)
+* [COMPLIANCE] Add Copyright and License Headers. [GH-580](https://github.com/hashicorp/raft/pull/580)
+
+IMPROVEMENTS
+
+* Bump github.com/hashicorp/go-hclog from 1.5.0 to 1.6.2. [GH-583](https://github.com/hashicorp/raft/pull/583)
+
+BUG FIXES
+
+* Fix rare leadership transfer failures when writes happen during transfer. [GH-581](https://github.com/hashicorp/raft/pull/581)
+
+# 1.6.0 (November 15th, 2023)
+
+CHANGES
+
+* Upgrade hashicorp/go-msgpack to v2, with go.mod upgraded from v0.5.5 to v2.1.1. [GH-577](https://github.com/hashicorp/raft/pull/577)
+
+  go-msgpack v2.1.1 is by default binary compatible with v0.5.5 ("non-builtin" encoding of `time.Time`), but can decode messages produced by v1.1.5 as well ("builtin" encoding of `time.Time`).
+
+  However, if users of this libary overrode the version of go-msgpack (especially to v1), this **could break** compatibility if raft nodes are running a mix of versions.
+
+  This compatibility can be configured at runtime in Raft using `NetworkTransportConfig.MsgpackUseNewTimeFormat` -- the default is `false`, which maintains compatibility with `go-msgpack` v0.5.5, but if set to `true`, will be compatible with `go-msgpack` v1.1.5.
+
+IMPROVEMENTS
+
+* Push to notify channel when shutting down. [GH-567](https://github.com/hashicorp/raft/pull/567)
+* Add CommitIndex API [GH-560](https://github.com/hashicorp/raft/pull/560)
+* Document some Apply error cases better [GH-561](https://github.com/hashicorp/raft/pull/561)
+
+BUG FIXES
+
+* Race with `candidateFromLeadershipTransfer` [GH-570](https://github.com/hashicorp/raft/pull/570)
+
+
+# 1.5.0 (April 21st, 2023)
+
+IMPROVEMENTS
+* Fixed a performance anomaly related to pipelining RPCs that caused large increases in commit latency under high write throughput. Default behavior has changed. For more information see #541.
+
+# 1.4.0 (March 17th, 2023)
+
+FEATURES
+* Support log stores with a monotonically increasing index.  Implementing a log store with the `MonotonicLogStore` interface where `IsMonotonic()` returns true will allow Raft to clear all previous logs on user restores of Raft snapshots.
+
+BUG FIXES
+* Restoring a snapshot with the raft-wal log store caused a panic due to index gap that is created during snapshot restores.
+
