Release Policy
Rucio follows a release policy, based on semantic versioning, with major (named) releases. Approximately every 4 months we produce a major release with a version number like x.0.0 (with x > 0). A major release marks the start of a release line. This release line is maintained with bi-weekly minor/patch releases, containing bug fixes or minor enhancements, with version numbers like 32.y.z (with y ≥ 0, z ≥ 0). Versions within one release line are always backwards compatible, thus they do not include database schema changes, API modifications, or other backward-compatibility breaking changes.
Previous to the 32 release line, Rucio used a different versioning theme.
Support period
A release line is only maintained with patch releases until the start of the next release line, thus approximately 4 months. Typically once a year we will designate a release line a Long-term Support (LTS) release line. This release line will be supported with security and critical patches for approximately two years. It is foreseen to have an overlap of at least 12 months between two LTS release lines, to give communities a comfortable time window to deploy the new LTS release.
Client ↔ Server compatibility
For differences between the versions of a Rucio client and a Rucio server we guarantee compatibility of an older client up until the oldest supported LTS release line. For example, with 1.29 LTS being the oldest supported release line, a 34 Rucio server guarantees support of clients of the 1.29, 1.30, 1.31, 32, 33 and 34 release line. Most likely older clients will work, without problems, as well, however, the release policy does not guarantee it.
Please be aware that we can not guarantee compatibility of a newer client with an older server.
