 Deprecations
 ~~~~~~~~~~~~
+* Deprecate :py:attr:`pvlib.location.Location.pytz`.
+  Use :py:attr:`~pvlib.location.Location.tz` instead. (:issue:`2343`, :pull:`2757`)

 Bug fixes
 ~~~~~~~~~
-* 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`)

+  data type integer. Users can expect modeled cell temperature values to

+* 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`)
+* 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`)

+  parameter now has no effect and will be removed in the future. (:pull:`2781`)
 
 
 Enhancements
