  8.x Series
 ============
 
+.. _version 8.8.0:
+
+IPython 8.8.0
+-------------
+
+First release of IPython in 2023 as there was no release at the end of
+December.
+
+This is an unusually big release (relatively speaking) with more than 15 Pull
+Requests merge.
+
+Of particular interest are:
+
+ - :ghpull:`13852` that replace the greedy completer and improve
+   completion, in particular for dictionary keys.
+ - :ghpull:`13858` that adds ``py.typed`` to ``setup.cfg`` to make sure it is
+   bundled in wheels.
+ - :ghpull:`13869` that implements tab completions for IPython options in the
+   shell when using `argcomplete <https://github.com/kislyuk/argcomplete>`. I
+   believe this also needs a recent version of Traitlets.
+ - :ghpull:`13865` makes the ``inspector`` class of `InteractiveShell`
+   configurable.
+ - :ghpull:`13880` that remove minor-version entrypoints as the minor version
+   entry points that would be included in the wheel would be the one of the
+   Python version that was used to build the ``whl`` file.
+
+In no particular order, the rest of the changes update the test suite to be
+compatible with Pygments 2.14, various docfixes, testing on more recent python
+versions and various updates.
+
+As usual you can find the full list of PRs on GitHub under `the 8.8 milestone
+<https://github.com/ipython/ipython/milestone/110>`__.
+
+Many thanks to @krassowski for the many PRs and @jasongrout for reviewing and
+merging contributions.

+work on IPython and related libraries.
