+===================================
+``discretize`` 0.12.0 Release Notes
+===================================
+
+October 8, 2025
+
+This minor release contains many bugfixes and updates related to new package builds.
+
+Python versions
+---------------
+`discretize` has bumped its minimum supported `python` version to 3.11, and is tested against versions 3.11-3.14. Minimum scipy versions
+have also been bumped to 1.12. Users on older python versions should continue to use `discretize` 0.11.x.
+
+We have also added support for (and tests against) free-threaded python builds for python 3.13 and later, which should be available through
+the normal python distribution channels (pypi, conda-forge).
+
+``TreeMesh`` updates
+--------------------
+Tree meshes now support a `refine_image` method that allows users to refine a mesh based on an image (2D or 3D numpy array). See
+:func:``discretize.TreeMesh.refine_image`` for more details.
+
+``TensorMesh`` updates
+----------------------
+A new :func:``discretize.TensorMesh.point2index`` method has been added to convert a point location to the corresponding cell index in
+a tensor mesh, similar to the existing :func:``discretize.TreeMesh.point2index`` method.
