+Version 5.4.2
+-------------
+
+Released on December 13, 2024.
+
+### Backward-incompatible API changes
+
+ -  Removed `ContextTimeoutOption` class. Instead, added `ContextOption` class.
+    The unit of the time-related options in `ContextOption` is millisecond,
+    whereas `ContextTimeoutOption` was second.  [[#4007]]
+ -  Removed `ConsensusReactorOption.ContextTimeoutOptions` property.
+    Instead, added `ConsensusReactorOption.ContextOption` property.  [[#4007]]
+ -  `ConsensusReactor` constructor requires `ContextOption` parameter
+    instead of the `ContextTimeoutOption` parameter.  [[#4007]]
+
+### Behavioral changes
+
+ -  `Gossip.RebuildTableAsync()` now bootstrap peers from the seed peers.
