More visibility into commits
Sentry can automatically retrieve commit data each time you deploy a new version of your app in Heroku. With commit data for each release, you can see which files have changed most recently and who pushed code, which helps debug new errors as they occur.
Releases also enable deploy emails so that team members are alerted when their code goes out.
Connect your Heroku repository
Connect your repository to your Sentry org. Enable the Heroku integration in your project settings. Configure the plugin to specify which repository and deploy environment. Copy the deploy hook command to your Heroku config from your release tracking settings.
