+## Unreleased
+
+### Added
+- [`installkernel()`](@ref) now supports a `displayname` argument to customize
+  the kernel display name ([#1137]).
+
+### Fixed
+- The internal heartbeat thread will now shut down cleanly ([#1135],
+  [#1144]). This should prevent segfaults upon exit.
+- Various fixes to the messaging code to be compliant with Jupyter ([#1138]).
