 ## 7.1.0
 
 IPykernel 7.1.0 fixes an issue where display outputs such as Matplotlib plots were not included when using `%notebook` magic to save sessions as `.ipynb` files (#1435). 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.

 ## 7.1.0
 
 IPykernel 7.1.0 fixes an issue where display outputs such as Matplotlib plots were not included when using `%notebook` magic to save sessions as `.ipynb` files (#1435). 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.
