+## 6.31.0
+
+IPykernel 6.31.0 fixes an issue where display outputs such as Matplotlib plots were not included when using `%notebook` magic to save sessions as `.ipynb` files. This is enabled using the traitlet `ZMQDisplayPublisher.store_display_history` which defaults to the previous behaviour of `False`. This is a minor release rather than a patch release due to the addition of the new traitlet.

 ## 6.30.0
 
 This release fixes three bugs but is primarily a maintenance release bringing support for Python 3.13 and updating dependencies. It does not include subshells which will be in the upcoming 7.0.0 release. Users and downstream libraries that wish to avoid subshells should pin to `ipykernel < 7`.
