   * Let papersizes `a0`, `a1`, `a2`, ... be case-insensitive by
     converting the case as needed in LaTeX and ConTeXt writers.
 
+  * Change `fixDisplayMath` from `Text.Pandoc.Writers.Shared`
+    so that it no longer produces empty `Para`'s as an artifact.

   * revealjs template:  add `tex2jax` configuration for the
     math plugin.  With the next release of reveal.js, this will
