Blender 2.80 compatibility, a new face-alignment option (and default behavior!) for "Align Planes" and a NEW INSTALL PROCESS are the big headlines with this version of Mesh Align Plus (free and open source as always!). The addon has now moved to the 3D View > N panel as well.
For the unfamiliar: Mesh Align Plus helps you align, move, measure and match things precisely in your 3D scenes. It's designed to provide precision modeling capabilities, especially for hard surface modelers, mechanical, architectural and CAD/CAM users. Check the links below for more info.
