Changelog
Keep yourself informed about the most recent additions and improvements
we’ve made to Sevalla.
Nixpacks version selection is here
You can now select your preferred Nixpacks version for your apps on Sevalla. This gives you more flexibility and control over your deployments, and helps ensure smooth upgrades.
Starting today, all newly created apps will use Nixpacks version 1.39 by default (previously 1.29). If you need to use a different version, simply choose the version that best fits your project.
System environment variables available in applications
We're introducing automatic injection of several system environment variables into your apps during both build and runtime. This makes it easier to automate tasks and access important deployment details directly from your application.
The following environment variables will be available:
- SVL_COMPANY_ID
- SVL_APP_ID
- SVL_APP_NAME
- SVL_DEPLOYMENT_ID
- SVL_DEPLOYMENT_INITIATED_BY
- SVL_DEPLOYMENT_TRIGGER
- SVL_DEPLOYMENT_COMMIT_SHA
- SVL_DEPLOYMENT_BRANCH
- SVL_DEPLOYMENT_DOCKER_IMAGE
Use these variables for enhanced automation and more flexible app behavior!
