Version 1.4.0

This version has some major changes including:

• Use the new pyuvdata analytic beams and remove all analytic beam specifications in pyuvsim.
• BeamLists now contain BeamInterface objects (but are still initialized with lists of UVBeam and/or Analytic Beam objects)
• Significant refactoring of BeamLists, removing the string/object mode and replacing it with a shared memory approach similar to what is done for SkyModel objects.
• Setting the select.bls property in the obsparams file now selects baselines before creating the UVData object, rather than down-selecting afterwards, saving memory and time.

The following dependency requirements were updated:

• Updated minimum dependency versions: pyuvdata>=3.1.0
• Updated minimum optional dependency versions: lunarsky>=0.2.5

Version 1.2.4

This release includes support for turning off a check during UVBeam interpolation that checks if the location being interpolated to is covered by the beam. With this release, that check is turned off by default if the beam covers the full sky horizon-to-horizon, and allows users to turn the check off by hand. Turning off this check can speed things up significantly.

Full details are in our changelog and in the automatically generated details below.
