 - Add TeX Gyre Heros as Helvetica-alternative (:pr:`95`). This is the new open-source default font.
 - Add `xlinewidth`, `ylinewidth`, `xgridcolor`, `ygridcolor` keyword
   args to `~proplot.axes.XYAxes.format` (:pr:`95`).
+- Add getters and setters for various `~proplot.subplots.Figure` settings like ``share[x|y]``,
+  ``span[x|y]``, and ``align[x|y]`` (:pr:`99`).
 - Add `~proplot.subplots.Figure` ``fallback_to_cm`` kwarg. This is used by
   `~proplot.styletools.show_fonts` to show dummy glyphs to clearly illustrate when fonts are
   missing characters, but preserve graceful fallback for end user.
