 New Features
 ^^^^^^^^^^^^
 
+- Added SDSS-V file format readers. [#1107]

 Bug Fixes
 ^^^^^^^^^
 
+- SDSS reader now properly exposes the ``spPlate_identify`` and ``spPlate_loader`` functions. [#1097]
+
+- Masks now round-trip through tabular-fits reader/write. [#1104]
+
 - ``template_correlate`` no longer errors when used on a ``Spectrum1D`` that lacks an
   ``uncertainty`` array. [#1118]
 
 - ``with_spectral_unit`` has been changed to ``with_spectral_axis_unit`` and actually works
   now. [#1119]
 
+- Template correlation functions now truncate to overlapping region to avoid NaNs in normalization
+  when spectrum and template have non-overlapping regions. [#1121]
+
 - Fixed numpy error when printing a ``Spectrum1D`` object. [#1123]
