13.3.3. Compatible-Versions

The Compatible-Versions element is a list of previous cartridge versions that are compatible with the current cartridge version.

Compatible-Versions: ['1.0.1']

To be compatible with a previous version, the code changes in the current cartridge version must not require a restart of the cartridge or of an application using the cartridge.

If the previous cartridge version is not in the Compatible-Versions list when you update the cartridge to a new version, OpenShift Enterprise stops the cartridge, installs the new code, runs setup, and restarts the cartridge. This process results in a short amount of downtime for applications that use the cartridge.
