The scalingo-20 stack, based on the Ubuntu 20.04 LTS operating system, is now deprecated.
Applications using scalingo-20 will continue to work. However, to ensure the security, performance, and reliability of both your applications and our platform, we strongly encourage you to plan their migration to scalingo-22, based on Ubuntu 22.04 LTS, as soon as possible.
The scalingo-22 stack, based on Ubuntu 22.04 LTS, will be supported until April 2027. This makes it a secure and sustainable choice for ensuring the continued functionality of your applications.
Deprecation Plan
- May 1, 2025: Usage exemption for legacy apps. Ubuntu 20.04 LTS and scalingo-20 officially reach end-of-life and will no longer receive updates. From this date, it is no longer possible to select this stack to create new applications. Existing applications using the scalingo-20 stack will continue to work normally, with the ability to create new deployments or Review Apps on this version.
- January 1, 2026: End of usage exemption. From this date, no new deployments are allowed on the scalingo-20 stack. Deployments made before this date continue to work, but all new deployments will be done using a supported stack.
Plan today
To ensure the security, performance, and reliability of your applications, we encourage you to migrate to scalingo-22 as soon as possible.
