The Build Config Validation feature is now in beta, and available for you to activate.
When active, the build config validation feature will validate and normalize any incoming build config sources, your
.travis.yml file and configs from build requests created via API.
You can enable this feature using the repository setting “Build config validation” in the Travis CI UI, or by specifying the version in your
version: ~> 1.0
Read more about this feature on our blog.
You can find the new build config reference documentation here.
