Xenial as the default build environment is coming

Ubuntu Xenial as the default Travis CI build environment is coming up next week, starting incrementally on Tuesday April 23rd, 2019 and aiming to be completed by the beginning of May, 2019.

During this time:

  • Repositories without an explicit dist: YAML key in their .travis.yml file will be routed to Xenial instead of Trusty.

  • Repositories without an explicit operating system os: key in their travis.yml file will use Linux Ubuntu Xenial 16.04.

If you'd like your builds to continue using Ubuntu Trusty 14.04, please make sure to specify dist: trusty in your .travis.yml file.
