+=============
+
+**July 2025**
+
+:mod:`sklearn.base`
+-------------------
+
+- |Fix| Fix regression in HTML representation when detecting the non-default parameters
+  that where of array-like types.
+  By :user:`Dea María Léon <deamarialeon>` :pr:`31528`
+
+:mod:`sklearn.compose`
+----------------------
+

+  By :user:`Nicolas Bolle <nicolas-bolle>`. :pr:`31079`
+
+:mod:`sklearn.datasets`
+-----------------------
+
+- |Fix| Fixed a regression preventing to extract the downloaded dataset in
+  :func:`datasets.fetch_20newsgroups`, :func:`datasets.fetch_20newsgroups_vectorized`,
+  :func:`datasets.fetch_lfw_people` and :func:`datasets.fetch_lfw_pairs`. This
+  only affects Python versions `>=3.10.0,<=3.10.11` and `>=3.11.0,<=3.11.3`.

+
+:mod:`sklearn.inspection`
+-------------------------

+  By :user:`Olivier Grisel <ogrisel>` :pr:`31556`
+
+:mod:`sklearn.utils`
+--------------------
+
+- |Fix| Fixed a spurious warning (about the number of unique classes being
+  greater than 50% of the number of samples) that could occur when
+  passing `classes` :func:`utils.multiclass.type_of_target`.
+  By :user:`Sascha D. Krauss <saskra>`. :pr:`31584`
