Reviving the existing news thread to make an announcement:
New v0.5.0 release is out! Install notes are here. Check out the in-depth discussion thread for more info in the released scripts subforum here.
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.
