10 - :ghpull:`14251` Fix a memory leak in qt event loop integration by setting
11 the Loop parent to None.
12 - :ghpull:`14252` Pickleshare was made an optional dependency in 8.17, this
13 leads to warnings in some installations when using modules completions. The
14 warning has been silenced.
15 - :ghpull:`14241` Update event loop code for compatibility with more recent
16 ``prompt_toolkit`` due to deprecations in Python 3.12.
17 - :ghpull:`14245` Fix doc example on Pygments styles
18 - :ghpull:`14238` Remove dependency on app_nope, this is actually only a
19 dependency of IPykernel.
