-Upcoming release (To be determined)
-===================================
+5.3.0 (Tuesday 8 October 2024)
+==============================
+
+This release primarily adds support for Python 3.13 and Numpy 2.0.
+
+NiBabel 6.0 will drop support for Numpy 1.x.
 
 New features
 ------------
+* Update NIfTI extension protocol to include ``.content : bytes``, ``.text : str`` and ``.json : dict``
+  properties for accessing extension contents. Exceptions will be raised on ``.text`` and ``.json`` if
+  conversion fails. (pr/1336) (CM)
 
 Enhancements
 ------------
- * Ability to read data from many multiframe DICOM files that previously generated errors
+* Ability to read data from many multiframe DICOM files that previously generated errors (pr/1340)
+  (Brendan Moloney, reviewed by CM)
+* ``nib-nifti-dx`` now supports NIfTI-2 files with a ``--nifti2`` flag (pr/1323) (CM)
+* Update :mod:`nibabel.streamlines.tractogram` to support ragged arrays. (pr/1291)
+  (Serge Koudoro, reviewed by CM)
+* Filter numpy ``UserWarning`` on ``np.finfo(np.longdouble)``. This can occur on
+  Windows systems, but it's done in the context of checking for the problem that
+  is being warned against, so there's no need to be noisy. (pr/1310)
+  (Joshua Newton, reviewed by CM)
+* Improve error message for for dicomwrapper errors in shape calculation (pr/1302)
+  (YOH, reviewed by CM)
+* Support "flat" ASCII-encoded GIFTI DataArrays (pr/1298) (PM, reviewed by CM)
 
 Bug fixes
 ---------
- * Fixed multiframe DICOM issue where data could be flipped along slice dimension relative to the
-   affine
- * Fixed multiframe DICOM issue where ``image_position`` and the translation component in the
-   ``affine`` could be incorrect
-
-Documentation
--------------
+* Fix location initialization/update in OrthoSlicer3D for permuted axes (pr/1319, pr/1350)
+  (Guillaume Becq, reviewed by CM)
+* Fix DICOM scaling, making frame filtering explicit (pr/1342) (Brendan Moloney, reviewed by CM)
+* Fixed multiframe DICOM issue where data could be flipped along slice dimension relative to the
+  affine (pr/1340) (Brendan Moloney, reviewed by CM)
+* Fixed multiframe DICOM issue where ``image_position`` and the translation component in the
+  ``affine`` could be incorrect (pr/1340) (Brendan Moloney, reviewed by CM)
 
 Maintenance
 -----------
+* Numpy 2.0 compatibility and addressing deprecations in numpy API
+  (pr/1304, pr/1330, pr/1331, pr/1334, pr/1337) (Jon Haitz Legarreta Gorroño, CM)
+* Python 3.13 compatibility (pr/1315) (Sandro from the Fedora Project, reviewed by CM)
+* Testing on Python 3.13 with free-threading (pr/1339) (CM)
+* Testing on ARM64 Mac OS runners (pr/1320) (CM)
+* Proactively address deprecations in coming Python versions (pr/1329, pr/1332, pr/1333)
+  (Jon Haitz Legarreta Gorroño, reviewed by CM)
+* Replace nose-era ``setup()`` and ``teardown()`` functions with pytest equivalents
+  (pr/1325) (Sandro from the Fedora Project, reviewed by Étienne Mollier and CM)
+* Transitioned from blue/isort/flake8 to `ruff <https://docs.astral.sh/ruff/>`__. (pr/1289)
+  (Dimitri Papadopoulos, reviewed by CM)
+* Vetted and added various rules to the ruff configuration for auto-formatting and style
+  guide enforcement. (pr/1321, pr/1351, pr/1352, pr/1353, pr/1354, pr/1355, pr/1357, pr/1358,
+  pr/1359, pr/1360, pr/1361, pr/1362, pr/1363, pr/1364, pr/1368, pr/1369)
+  (Dimitri Papadopoulos, reviewed by CM)
+* Fixing typos when found. (pr/1313, pr/1370) (MB, Dimitri Papadopoulos)
+* Applied Repo-Review suggestions (Dimitri Papadopoulos, reviewed by CM)
 
 API changes and deprecations
 ----------------------------
+* Raise :class:`~nibabel.spatialimages.HeaderDataError` from
+  :func:`~nibabel.nifti1.Nifti1Header.set_qform` if the affine fails to decompose.
+  This would previously result in :class:`numpy.linalg.LinAlgError`. (pr/1227) (CM)
+* The :func:`nibabel.onetime.auto_attr` module can be replaced by :func:`functools.cached_property`
+  in all supported versions of Python. This alias may be removed in future versions. (pr/1341) (CM)
+* Removed the deprecated ``nisext`` (setuptools extensions) package. (pr/1290) (CM, reviewed by MB)
