 Bug fixes
 ~~~~~~~~~
-* Added test coverage for :py:func:`pvlib.irradiance.dirint` with
-  ``np.array`` and ``pd.Series`` inputs. 
-  (:issue:`2751`, :pull:`2752`)
-* Corrects a bug in :py:func:`pvlib.temperature.fuentes`. If inputs were
-  data type integer, users can expect modeled cell temperature values to
-  increase slightly.
-  (:issue:`2608`, :pull:`2745`)
-* Fixes a regression in :py:func:`pvlib.tracking.calc_surface_orientation`
+* Fix :py:func:`pvlib.temperature.fuentes` truncating the output if `poa_global` input was
+  data type integer. Users can expect modeled cell temperature values to
+  increase slightly. (:issue:`2608`, :pull:`2745`)
+* Fix a regression in :py:func:`pvlib.tracking.calc_surface_orientation`
   introduced in v0.15.1 (:pull:`2702`) that caused a broadcasting
   ``ValueError`` when ``tracker_theta`` was a 2-D (or higher rank) array.
   (:issue:`2747`, :pull:`2749`)
 * Document that timestamps returned by :py:func:`~pvlib.iotools.get_era5`
   represent the end of the averaging interval, consistent with ERA5
   conventions. (:issue:`2772`, :pull:`2773`)
-
-* :py:func:`pvlib.iotools.read_nsrdb_psm4` now parses the file header with the
-  :py:mod:`csv` module instead of a naive ``str.split(',')``, so quoted column
-  names containing commas (e.g. the material names in spectral-on-demand files)
-  are no longer split into spurious columns. (:issue:`2736`, :pull:`2771`)
+* Fix header parsing in :py:func:`pvlib.iotools.read_nsrdb_psm4` with quoted
+  commas in column names. This allows spectral-on-demand files to be read. (:issue:`2736`, :pull:`2771`)
 * Update :py:func:`~pvlib.iotools.get_meteonorm_tmy` to comply
   with the updated Meteonorm API.  As part of this, the ``data_version``
   parameter now has no effect and will be removed in the future. (:pull:`2781`)
 
+
 Enhancements
 ~~~~~~~~~~~~
+* Add the ``front_side_fraction`` parameter to
+  :py:func:`pvlib.snow.loss_townsend` to support Townsend snow-loss
+  workflows for bifacial systems. (:issue:`2755`, :pull:`2756`)
 * Add the following parameters to :py:func:`~pvlib.iotools.get_nasa_power`
   when ``map_variables=True``: ``temp_dew``, ``precipitable_water``,
   ``relative_humidity``, ``ghi_extra``, ``dhi_clear``, ``longwave_down``,
-  and ``albedo``.
-  (:issue:`2731`, :pull:`2753`, :pull:`2762`)
+  and ``albedo``. (:issue:`2731`, :pull:`2753`, :pull:`2762`)
 
 
 Documentation
 ~~~~~~~~~~~~~
-* Clarifies that :py:func:`pvlib.soiling.hsu` has an implicit minimum
+* Clarify that :py:func:`pvlib.soiling.hsu` has an implicit minimum
   soiling ratio of approximately 0.6563 due to the mathematical form
   of the model. (:issue:`2534`, :pull:`2743`)
-* Clarifies how Linke turbidity values can be provided to
- :py:func:`pvlib.clearsky.ineichen` via
- :py:func:`pvlib.clearsky.lookup_linke_turbidity` (:issue:`2598`, :pull:`2746`)
+* Clarify how Linke turbidity values can be provided to
