There were several bug fixes as well as two major features:

Material Design

Material design was integrated into the site. This can be seen several places including the new buttons, check boxes and radio buttons.

Homepage Re-Design

The homepage redesign changed the look and feel of several aspects of the homepage. These changes can really be seen on the mobile site. The mobile site is now much more user friendly and iSENSE's features can be more easily accessed from the mobile site.
