 ## [Unreleased]
 
 ### Added
+- Added a `uvw_track_generator` method within `utils` for calculating the expected
+uvws (and a few other values) without needing to instantiate a whole `UVData` object.
+- Added a convenience function called `compare_value` in `UVParameter` that enables
+one to do value checking with tolerances accounted for.
 - Support for recarrays in `UVParameter` objects and in `UVBase`, needed for pyradiosky.
 - Support for setting the astrometry library for various object methods including `set_lsts_from_time_array`, file read methods and others.
 - Properly round-trip the telescope frame through UVH5, UVFITS and MS files.
