Travis-CI has or will shortly make in early December 2018 a number of beneficial changes to their Linux continuous integration testing infrastructure . An accompanying benefit of this change is that Ubuntu Xenial (16.04 LTS) is now supported.
The benefits for piglit are primarily:
- Testing against a more modern, supported Ubuntu Xenial (16.04 LTS). 
- Removal of a corner-case for Python 3.7, making testing more consistent.
- Modest speed improvements from Travis-CI's move to Linux infrastructure combined into one (virtualized), from two previously (virtualized and container-based).
