+0.16
     - fixed handling colors when 'termguicolors' is set

     - set b:current_syntax in syntax/shelloutput.vim which fixes rendering
       shelloutput in Neovim via the treesitter fallback

-      rewritten in this version of Neovim in a non-compatible way
-    - vimhl 0.3.0.0 - 0.3.2.0: many improvements (see release notes at github)
-    - update the sample .vimrc.pandoc to use with Neovim
