+dxtbx 3.16.0 (2023-08-14)
+=========================
+
+Features
+--------
+
+- Add new Beam class ``dxtbx.model.PolychromaticBeam``, for polychromatic/multi-wavelength/wide bandpass experiments. (`#621 <https://github.com/cctbx/dxtbx/issues/621>`_)
+- Formats: Reflect move of Eiger detector from PETRA P14 to P13. (`#626 <https://github.com/cctbx/dxtbx/issues/626>`_)
+- The ``model.Beam`` object now has a ``probe`` value to keep track of the type of radiation. (`#647 <https://github.com/cctbx/dxtbx/issues/647>`_)
+- Formats: CBFMini support for the EIGER2 16M detector at CHESS beamline ID7B2, which has an inverted rotation axis. (`#649 <https://github.com/cctbx/dxtbx/issues/649>`_)
+- Formats: Support for Eiger 9M on ESRF ID23-2, which has an undeclared vertical goniometer. (`#651 <https://github.com/cctbx/dxtbx/issues/651>`_)
+- Formats: Partial support for the Rigaku Oxford Diffraction file format, including support for multi-axis goniometers and faster decompression. (`#645 <https://github.com/cctbx/dxtbx/issues/645>`_) (`#653 <https://github.com/cctbx/dxtbx/issues/653>`_)
+
+
+Bugfixes
+--------
+
+- Panel geometry definitions in PHIL are merged by panel id *before* constructing panels. (`#299 <https://github.com/cctbx/dxtbx/issues/299>`_)
+- ``flumpy``: Fix case where incorrect ``flex.vec2``, ``flex.vec3`` could be generated. (`#439 <https://github.com/cctbx/dxtbx/issues/439>`_)
+- NXmx files with multidimensional arrays (images, modules, or both) are now handled. (`#612 <https://github.com/cctbx/dxtbx/issues/612>`_)
+- Slicing of imageset objects is now consistently 0-based, including for the sliced data accessor. Previously, the data accessor had to be accessed with the original index offsets. (`#633 <https://github.com/cctbx/dxtbx/issues/633>`_)
+- Formats: Add fix for Eiger / NXmx data from DLS i19-2, to correctly assign the image bit depth. (`#652 <https://github.com/cctbx/dxtbx/issues/652>`_)
