v7.1.0

Compare Source

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.

Output from threads is restored to the pre-6.29 behavior by default (route to latest cell, unless get_ipython().set_parent() is called explicitly from the thread. If it is called, output from that thread will continue to be routed to the same cell). This behavior is now opt-in, instead of unconditional (#​1451).

This release also fixes bugs that were introduced into the 7.x branch relating to Matplotlib plots in separate windows not being displayed correctly (#​1458), kernels launched in new threads failing asserts (#​1455), and ContextVars persisting between cells (#​1462). There is also a fix for keyboard interrupts on Windows (#​1434).

v7.0.0

Compare Source

IPykernel 7.0.0 is a major release containing experimental support for kernel subshells.

If not using subshells it is intended to be backward compatible with the 6.x branch, but there are some architectural changes which may break assumptions made in downstream libraries and hence this is identified as a major releases as it is potentially backwards incompatible. If you experience problems then please report them, and you can pin ipykernel < 7 if necessary.

For further information and to report problems please see ipykernel 7.0.0 release with subshells (issue 1438).
