SimPEG 0.18.1 Release Notes
===========================

November 9th, 2022

This release patches a few small bugs from the previous release.

Bug Fixes
=========

Several small bugs have been squashed

* DC 2D cell centered fields now respect the boundary conditions when querying for current density and the electric field.
* For the 1D electromagnetic simulations, `LineCurrent` sources were not being correctly queried to verify they were above the surface. They now also respect the `current` attribute.
* The `alpha_phi` property was not properly hooked into the `__init__` function of `PGI` regularization.
* When determining the quasi geology model of `PGI`, we were incorrectly applying the model mappings to the reference model, (inconsistent with its definition).
* Removed dependance on ``six`` package, as we haven't supported python 2 for a while, and cleaned up leftover `future` imports.
