 - Added a `check_surface_based_positions` positions method for verifying antenna
 positions are near surface of whatever celestial body their positions are referenced to
 (either the Earth or Moon, currently).
+- Added a switch to `UVData.write_ms` called `flip_conj`, which allows a user to write
+out data with the baseline conjugation scheme flipped from the standard `UVData`
+convention.
+- Added the `utils.determine_pol_order` method for determining polarization
+order based on a specified scheme ("AIPS" or "CASA").
 
 ### Changed
 - Increased the tolerance to 75 mas (equivalent to 5 ms time error) for a warning about

 - Changed the behavior of checking of telescope location to look at the combination of
 `antenna_positions` and `telescope_location` together for `UVData`, `UVCal`, and `UVFlag`.
 Additionally, failing this check results in a warning (was an error).
+- Changed `UVData.write_ms` to sort polarizations based on CASA-preferred ordering.
+- Added some functionality to the `utils._convert_to_slices` method to enable quick
+assessment of whether an indexing array can be replaced by a single slice.
