Sentry uses Travis CI for continuous integration and automation, including creating Sentry Releases with automated builds triggered by commits to the master branch. To set up this process, you need to configure a `.travis.yml` file that defines your project's language and version number, as well as environment variables such as the Sentry organization and project slugs. You then use the Sentry command line interface (CLI) to create a new release after the build phase has completed successfully, associating it with the commits from your local repository. To trigger this process, you need to push a new commit to your GitHub repository, and verify that the Sentry Releases are working by checking the Travis CI admin backend and the Sentry account's "Releases" page.
