Changes in version 0.1.8.9000                      

  - Fix issue with default arguments in aw_interpolate causing
    unnecessary errors

                 Changes in version 0.1.7 (2020-07-23)                  

  - Address situations where the geometry column has a different name.
    In prior versions, it was renamed. Now, we use an approach that does
    not require a specific geometry column name but should work
    regardless of what its name is.
  - Address CRAN warning with vignette rendering.

                        Changes in version 0.1.4                        

  - Fix issue where mixed interpolations with multiple extensive and
    intensive variables would get incorrect output containing two copies
    of the extensive results.

  - Patch fix to Issue 6 so that data not requiring the geometry
    collection fix do not get processed through that code, improving
    performance for those interpolations.

  - Updated draft of JOSS paper manuscript along with appendix code and
    response to reviewers added in paper/.

    collection

  - Fix Issue 7 - interpolation returns NA values when tid and sid are
    the same variable name (e.g. both are GEOID)

  - Fix Issue 14 - interpolation fails when the sf geometry column is
    not named geometry - now renamed on the fly if this is not the case

  - Fix Issue 16 - tibble output missing other output variables

  - Full draft of JOSS paper manuscript added in paper/
