Release of IPython 7.12

Hi all,

IPython 7.12 was released a couple of minutes ago, and is now available on PyPI, soon on conda-forge.

As usual monthly releases on the last friday of each month. Thanks to all the contributors !

pip install ipython --upgrade

And if you are using conda, once available on conda-forge:

conda upgrade ipython

Still a lot of cleanup going on, and some compatibility with a couple of new version of some packages so look at the full changelog to see if it affects you. Still trying to find some time to work on larger changes and awesome features.
