SimPEG 0.14.3 Release Notes
===========================

November 19th, 2020

This release mostly contains bug fixes and/or smaller additions to the code base
that add additional functionality. We apologize for the delay caused by testing
difficulties.

New Things
==========
There is now a file reader for UBC formatted gravity gradient data files.

The  class ``SimPEG.electromagnetics.frequency_domain.sources.LineCurrent`` now accepts
a keyword argument option ``current`` to set the strength of the ``LineCurrent``.
This is similar behavoir to ```SimPEG.electromagnetics.frequency_domain.sources.CircularLoop``.

There are now a few more default options that are setting for the plotting routines
in ``SimPEG.utils.plot_utils.plot2Ddata``. We also now specifically overriding these default
options for ``norm``, ``levels``, and ``zorder`` for the ``contourOpts`` dictionary
input. There is also now a ``streamplotOpts`` dictionary input as well to handle
keyword arguments to the stream plot.

This release will also be compatible with upcoming changes to the ``discretize``
package.

Bugs Squashed
=============

The sign convention when reading in the UBC gravity files has been adjusted to match
SimPEG's coordinate system convention. SimPEG uses a right handed coordinate system,
with z being positive upwards, whereas in the UBC file, gravity was defined as positive
downwards.

The user provided mapping for ``SimPEG.simulation.LinearSimulation`` was not being
properly taken into account, and has now been fixed.

We have re-anabled the mu inverse testing of ``SimPEG.electromagnetics.frequency_domain``
classes, ensuring those tests also pass.
