You can find out the highlights of the Ubuntu 16.04 by reviewing the release notes.

The biggest change to be aware of is Ubuntu 16.04 has moved to Python 3; if you are using this project for Python development or just using Python scripts/apps you may encounter breaking changes. You can review the Python 3 changes in the what’s new documentation.
