[csyhuang]

This is a tentative list of new features/functionality in release 0.7.0. The target release date would be 2023/6/1 (it may change depending on the progress of publication in our group).

Additional functionalities to include:

• Generalize the direct inversion algorithm to handle data of arbitrary lon/lat resolution #46
• Redesign the readme.md and make it a roadmap, e.g. "What do you want to do? If (A), go to (module name)..."
• Better encapsulate the option northern_hemisphere_results_only in QGField.
• (tentative) Non-QG formalism of LWA

The following item may be left for the next release:

• Comprehensive unit tests for QGField

---

The two items below will be left for release v0.7.1 #75

• Solve Memory Issues of QGField #50
• Generalize hemisphere_to_global to be used for both numpy and xarray interface #48

Reminder for users:

• Inversion using intel's numpy and scipy is much faster
