I tested this link and the page returned Error: DOI Not Found. I am guessing it takes a little while for doi.org to populate with the latest release?

Ah no, that will only go live once we publish the release. We need the tagged version before we can actually publish on Zenodo so we have to reserve the DOI, release, and then upload the code archive.

Ah, that makes sense. Good to know!


Bug fixes:

* **Profile distances are now returned in projected (Cartesian) coordinates by
the** ``profile`` **method of gridders if a projection is given.** The method
has the option to apply a projection to the coordinates before predicting so
we can pass geographic coordinates to Cartesian gridders. In these cases, the
distance along the profile is calculated by the ``profile_coordinates``
function with the unprojected coordinates (in the geographic case it would be
degrees). The profile point calculation is also done assuming that
coordinates are Cartesian, which is clearly wrong if inputs are longitude and
latitude. To fix this, we now project the input points prior to passing them
to ``profile_coordinates``. This means that the distances are Cartesian and
generation of profile points is also Cartesian (as is assumed by the
function). The generated coordinates are projected back so that the user gets
longitude and latitude but distances are still projected Cartesian meters.
(`#231 <https://github.com/fatiando/verde/pull/231>`__)
* **Function** ``verde.grid_to_table`` **now sets the correct order for
coordinates.** We were relying on the order of the ``coords`` attribute of
the ``xarray.Dataset`` for the order of the coordinates. This is wrong
because xarray takes the coordinate order from the ``dims`` attribute
instead, which is what we should also have been doing.
(`#229 <https://github.com/fatiando/verde/pull/229>`__)

Documentation:

* Generalize coordinate system specifications in ``verde.base.BaseGridder``
docstrings. Most methods don't really depend on the coordinate system so use
a more generic language to allow derived classes to specify their coordinate
systems without having to overload the base methods just to rewrite the
docstrings.
(`#240 <https://github.com/fatiando/verde/pull/240>`__)

New features:

* New function ``verde.convexhul_mask`` to mask points in a grid that fall
outside the convex hull defined by data points.
(`#237 <https://github.com/fatiando/verde/pull/237>`__)
* New function ``verde.project_grid`` that transforms 2D gridded data using a
given projection. It re-samples the data using ``ScipyGridder`` (by default)
and runs a blocked mean (optional) to avoid aliasing when the points aren't
evenly distributed in the projected coordinates (like in polar projections).
Finally, it applies a ``convexhul_mask`` to the grid to avoid extrapolation
to points that had no original data.
(`#246 <https://github.com/fatiando/verde/pull/246>`__)
* New function ``verde.expanding_window`` for selecting data that falls inside
of an expanding window around a central point.
(`#238 <https://github.com/fatiando/verde/pull/238>`__)
* New function ``verde.rolling_window`` for rolling window selections of
irregularly sampled data.
(`#236 <https://github.com/fatiando/verde/pull/236>`__)

Improvements:

* Allow ``verde.grid_to_table`` to take ``xarray.DataArray`` as input.
(`#235 <https://github.com/fatiando/verde/pull/235>`__)

Maintenance:

* Use newer MacOS images on Azure Pipelines.
(`#234 <https://github.com/fatiando/verde/pull/234>`__)
