The plugin did break on upgrading to the newest version. I'm not sure what version number I had before but I think it was <3 where this is in the changelog:
Allow widgets to query by post type and/or taxonomy & term instead of just one or the other. (Props: @vernal)
Taxonomy and term should have defaulted to Ignore in my opinion, because nothing showed up.
It's a minor problem, otherwise the plugin is simple and does one thing and one thing only, which is exactly what I look for.
