Changelog
Keep yourself informed about the most recent additions and improvements
we’ve made to Sevalla.
Faster app hibernation wake-up
Hibernated apps now wake up much faster, so your app becomes responsive more quickly after a period of inactivity. Previously, apps could take 60–90 seconds to start up after being idle, but now they’re ready in just 8–20 seconds.
Keep in mind that your app needs a redeploy to activate the new hibernation settings.
UPDATE #1:
In our excitement to bring you significantly faster wake-up times, it seems we shared this update a bit too early. We've since discovered that the changes introduced unforeseen problems for some of our customers.
To ensure stability for everyone, we have temporarily reverted this feature. We are working hard to address the issues and will keep you updated on our progress.
In the meantime, we advise every customer with a hibernation-enabled application to please perform a manual deployment of your app again. This will ensure it reverts to the previous, stable hibernation settings.
Thank you for your patience and understanding. 🙇♂️
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!
