This release has a few fixes and features in it:
a) Ability to use the address as the link text, if you are using the map link.
b) Ability to use measurements like % and px in your iframe width/height if you are using an embedded map.
c) https instead of http for all Google Maps links.
d) Update to how the information bubble works, since apparently Google Maps updated how it works.
You should not experience any problems if you upgrade to this new version. I hope. :)
