+# Major updates in this version
+In the time since it was initially published [@pyuvdata_v1], pyuvdata has undergone a
+significant expansion in capabilities. In addition to general performance improvements
+and restructuring, the newest version of pyuvdata includes several new major features,
+including:
+
+- The addition of the `UVCal` class, which provides a container for handling calibration
+solutions (bandpass, delays, and gains) for interferometric data. Supported data formats
+include MS, FHD, CalFITS, and CalH5.
+- The addition of the `UVBeam` class, which provides a container for handling models
+of the primary beam for antennas within an interferometric array. Supported data formats
+include BeamFITS and MWA.
+- The addition of the `UVFlag` class, which provides a container for handling flags/masking
+of bad data for visibility data.
+- Drastically improved handling of astrometry and increased speed and accuracy of algorithms
+used to ``phase-up'' data (i.e., change the sky position where the interferometer is centered
+up on).
+- Support for several new visibility data formats, including MIR, MS, UVFITS, and MWA/MWAX.
+- Support for data sets containing multiple spectral windows.
+- Support for data sets containing observations of multiple sources/phase centers.
