Maintenance policy¶

Our goal is to ensure that InvenioRDM Long-Term Support releases are supported with bug and security fixes for minimum one year after the release date and possibly longer. We aim at having new major releases every 3-months, especially in the early life of InvenioRDM. We strive our best to ensure that upgrades between major versions are fairly straight-forward to ensure users follow our latest releases.

The maintenance policy is striving to strike a balance between maintaining a rock solid secure product while ensuring that users migrate to latest releases and ensuring that we have enough resources to actually support the maintenance policy.

Policy¶

Long-Term Support (LTS) releases: A major version release may be designated as an LTS release. Only LTS releases should be used for production services. LTS releases are supported with bug and security fixes for a minimum of 1 year and possibly longer. An LTS release is supported for 6 months after the next LTS release. Only the latest minor-level release for the major version is supported. Example, if v6.0 is designated an LTS release, then only the latest v6.X release is maintained, as minor and patch-level releases

Major release: Major versions such as v3 allow us to introduce new features and make backward incompatible changes and remove deprecated features in a progressive manner. Only the latest minor-level release for each major version is supported. A major version release is supported until the next major version release (except for LTS designated releases).

Minor releases: Minor versions such as v3.1 allow us to introduce backward compatible changes in a manner that allow users to easily upgrade.

Patch releases: Patch versions such as v3.0.1 allow us to fix bugs and security issues in a manner that allows users to upgrade immediately without breaking backward compatibility.

We may make exceptions to this policy for serious security bugs.
